Introduction TIMKEN SPHERICAL ROLLER EARINGS Timken spherical roller bearings exceed industry standards for superior quality and performance and are designed to manage high radial loads, even when misalignment, marginal lubrication, contamination, extreme speeds, or critical application stresses are present. That s why industries such as power generation, oilfield, steel, aggregate, cement, mining and power transmission turn to Timken for a complete line of high-performance spherical roller bearings. Through expertly designed critical dimensions, such as roller and raceway contact geometry and topography, our spherical roller bearings are helping customers increase productivity by reducing downtime and extending maintenance cycles. In addition to the CJ and YM/YM designs, Timken spherical roller bearings can be ordered with several enhancements and modifications to extend life and improve performance in specific applications. For example, large-bore spherical bearings sometimes operate below the bearing s published speed rating, causing the cage to push a non-rotating roller across the raceways. This sliding action breaks down lubrication film and can ultimately damage the bearing. To help protect the bearing components, our engineered surfaces coating minimizes skidding and sliding damage, while withstanding small-particle contamination. In some cases, engineered surfaces can extend bearing life by up to five times standard designs, especially in demanding applications like paper and rolling mills. PRODUCT READTH Timken offers a complete line of spherical roller bearing designs ranging from 2 to 00 millimeter bore (0.98 to 9.06 inches). Included in this broad portfolio are two fundamental design types: the Type CJ style and Type YM/YM design. Available in 2 to 200 millimeter bore (0.98 to 7.87 inches), Type CJ-style bearings offer higher load ratings for longer life and incorporate a stamped steel window-type cage. Similar to all spherical roller bearings, the CJ design compensates for dynamic and static misalignment and allows customers to use weldments for housing frames instead of complex castings. Type YM bearings feature precision-machined, roller-riding brass cages and are designed for harsh industrial environments. These bearings offer higher load ratings for longer life. For larger bore sizes, the Type YM design incorporates an inner-ring, land-riding cage. The YM/YM design is produced in sizes ranging from 0 to 00 millimeter bore (.8 to 9.06 inches).

SPHERICAL ROLLER EARING CATALOG ROLLER EARINGS TO IDENTIFY: SPHERICAL ROLLER EARINGS The basic bearing number, plus any applicable modification code, is marked on the outer ring face (e.g., 22CJW). If the bearing has a tapered inner ring bore, the letter K is marked on the inner ring face (in addition to the above outer ring face marking). Replacement bearings, if straight bore, should be ordered by specifying bearing number plus the suffix nomenclature marked on outside face (e.g., 22CJW). Replacement bearings, if a tapered bore, should be ordered as described above, except include the suffix K following basic bearing number (e.g., 22KCJW). Note: Letter symbols marked on recessed pads on ring faces are not part of bearing nomenclature and therefore not relevant to replacement bearing number identification. For a comprehensive description of spherical roller bearing nomenclature, see page 76. CJ earing Number Locations Straight ore Letter K Tapered ore TO IDENTIFY: SPHERICAL ROLLER EARING PILLOW LOCK The end cap and/or base housing is marked with a pillow block housing number (e.g., SAF7). The pillow block assembly number is closely affiliated with the housing number (e.g., SAF227). Here, pillow block assembly uses the pillow block housing SAF7.

INTRODUCTION Timken is a leader in the advancement of bearing technology. Expert craftsmanship, well-equipped production facilities, and a continuing investment in technology programs ensure that our products are synonymous with quality and reliability. Today, our plants manufacture thousands of bearing types and sizes to handle a wide range of application requirements. ENGINEERING Anti-friction bearings inherently manage broad ranges of speed and many combinations of radial and thrust loads. Environmental conditions such as low and high temperature, dust and dirt, moisture, and unusual mounting conditions, affect bearing operation. If complex bearing applications are involved, consult your Timken representative. A ROLLER EARING SELECTION PROCESS earing selection is a process of evaluating the suitability of bearings for specific industrial applications. The quality of the available information to make these selections will play a major role in determining the success of the bearing choice. The first step in bearing selection is identifying the proper roller element type, whether it is a ball, needle, cylindrical, spherical or tapered roller bearing. Each roller bearing type has advantages and disadvantages that are design-specific and will affect such things as the loads and speeds the bearing can sustain in the application. Next, assess the size constraints of the bearing envelope or available space. This is done by considering the minimum shaft diameter, maximum housing bore and available width in the bearing application. After the bearing envelope is defined, search the catalog for bearings with bores, outer diameters and widths that will fit in the bearing envelope. There may be several bearings with different load-carrying capacities available that fit in the envelope. Of the bearings fitting the envelope, the next step is to determine which of these bearings will give the desired life in the application by performing a bearing life analysis. The bearing selection is completed once the design options are chosen. These options include cage type, cylindrical roller bearing flange arrangements, radial internal clearance or setting, and precision level and lubrication. These options are selected based on the application s speed, temperature, mounting and loading conditions, and will enable you to achieve optimum bearing performance and life. This catalog assumes that a spherical roller bearing has been selected for the application, and highlights the data and methods to use during the selection process. For a closer look, your Timken representative can provide you with expert computer analysis to give you the most detailed information for your bearing application.

ENGINEERING A A RADIAL SPHERICAL ROLLER EARINGS The principle styles of radial spherical roller bearings that Timken offers are: CJ, YM, YMD, and YM. CJ YM / YM Tapered ore earing with Adapter Sleeve Assembly Fig.. Common design styles of Timken spherical roller bearings. YM bearings offer the greatest range of sizes in all series. They combine design experience with proven performance in many industries. All of the newer styles (CJ, YM, YM and YMD) offer higher load ratings for longer life. CJ bearings include a stamped steel, window style cage and are suitable for a broad range of general service applications. For extreme conditions of use, the YM, YM and YMD styles with a machined brass cage should be considered. All styles are available in straight or tapered bores. Tapered bore bearings can be ordered by placing a K immediately after the numbers in the bearing description (e.g., 22KYM). Tapered bore bearings are available with adapter sleeve assemblies consisting of sleeve, locknut and washer. Adapter sleeve assemblies are designated SNW (e.g., SNW7). Timken spherical roller bearings have been developed to accommodate radial and axial loads. The internal geometry allows the inner ring to accommodate misalignment. This capability is unique to spherical roller bearings, allowing machine designers more tolerance and less restrictive assembly. Other data is listed. Timken spherical roller bearings are available in a ten dimensional series conforming to ISO and ANSI/AMA standards. See Fig. 2 for size range illustration. OPTIONAL FEATURES AVAILALE WITH TIMKEN SPHERICAL ROLLER EARINGS W Lubrication Groove and Oil Holes A lubrication groove and three oil holes are provided in the bearing outer ring. This eliminates the expense of machining a channel in the housing bore for introducing lubricant to the bearing. This design feature allows the lubricant to flow between the roller paths, through a single lubrication fitting. The lubricant moves laterally outward from the center of the bearing, reaching all contact surfaces and flushing the bearing. To order, add the suffix W to the bearing number (e.g., 2226CJW). W22 Selected Outside Diameter earings earings with selected outside diameters are required in some applications. Timken spherical roller bearings are available with reduced outside diameter tolerance. This allows a close control of the fit between the bearing and housing. To specify this feature, add the suffix W22 to the bearing number (e.g., 2226CJW22). Additional features are available, consult your Timken representative for more information. Fig. 2. Standard ISO/AMA series available from Timken. 8 SPHERICAL ROLLER EARING CATALOG

ENGINEERING CAGE DESIGNS Cages (sometimes referred to as rolling element separators or retainers) perform an important function in the proper operation of rolling bearings. They maintain uniform rolling element spacing in the races of the inner and outer rings of the bearings as the rolling elements pass into and out of the load zones. Timken has developed cage types to meet various service requirements. Temperature limitations are described in the temperature limitations portion of the Engineering section on page 70. A CAGE DESCRIPTIONS rass Cages YM, YM and YMD bearing cages are centrifugally cast and precision machined from brass. (Note that the brass grades used are often commercially termed bronze.) Their rugged construction provides an advantage in more severe applications. The open-end design permits lubricant to reach all surfaces easily, assuring ample lubrication and a cooler running bearing. YM and YM are both one-piece designs that are differentiated by their means of guidance within the bearing. With YM designs, the cage mass is low and the rollers are used for guidance, while YM cage designs typically have more mass and guide on the inner ring. YMD cages are similar to YM, except they have a two-piece design. Two independent cages, one for each row of rollers, are assembled into an individual bearing. This allows each row of rollers to rotate independently when required by the application, and prevents bending of the cage fingers. VCSM designs are similar to YM in that they are single piece, finger style cages. Stamped Steel Cages These cages are used in CJ design to permit extra load carrying capabilities in the bearing compared to YM and YM designs. This is accomplished through the use of a window style cage, which retains the rollers axially thus eliminating the need for ribs on the inner ring and allowing longer rollers. The window style cage is also held on both ends as opposed to finger style cages, thus allowing thinner bridge sections and often more rollers. The CJ design also has two independent cages, one for each row of rollers, assembled in an individual bearing. This feature serves to prevent cage bending when the operating environment is favorable for this to occur. Some CJ bearings utilize a cast iron floating ring to guide the cage. Use of the floating ring is based on size and mass of the cage. The VCSJ design is a finger style cage, similar to the VCSM, however it is pressed steel instead of brass. YM Cage YM Cage CJ Cage Pin Type Cages Large diameter spherical roller bearings can be supplied with these cages. The design of pin type cages permits an increased roller complement, giving the bearing enhanced load carrying ability. Consult your Timken representative for suggestions on the application of this cage. Pin Type Cage Fig.. Common cage styles for Timken spherical roller bearings. SPHERICAL ROLLER EARING CATALOG 9

SHOCK LOADS It is difficult to determine the exact effect that shock loading has on bearing life. The magnitude of the shock load depends on the masses of the colliding bodies, their velocities, and deformations at impact. The effect on the bearing depends on how much of the shock is absorbed between the point of impact and the bearings, as well as whether the shock load is great enough to cause bearing failure. It also is dependent on frequency and duration of shock loads. As a minimum, a suddenly applied load is equivalent to twice its static value. It may be considerably more than this, depending on the velocity of impact. Shock involves a number of variables that generally are not known or easily determined. Therefore, it is good practice to rely on experience. Timken has years of experience with many types of equipment under the most severe loading conditions. Your Timken representative should be consulted on any application involving unusual loading or service requirements.

ENGINEERING A A DETERMINATION OF APPLIED LOADS AND EARING REACTIONS - continued EARING REACTIONS To allow for misalignment between the shaft and housing axes, a spherical roller bearing is self-aligning. That is, the effective center for each row of rollers intersects the shaft axis at the bearing geometric center as shown in Fig. 2. As the distance between effective centers for each row of a bearing is zero (i.e. zero moment arm), a pure couple cannot be generated internal to the bearing. Therefore, when a shaft and housing are misaligned, the inner and outer rings of the bearing rotate up to a few degrees relative to each other, without creating internal forces. This self-aligning capability in turn prevents an external moment load from being supported by the bearing. Therefore, spherical roller bearings can only accommodate external shaft and housing loads through radial and axial reaction forces. Typically, one bearing on a shaft system is fixed axially and reacts radial and axial forces. The other bearings on the shaft are usually mounted with loose fits and axial space to allow movement, or float, for environmental conditions such as uneven thermal growth between the shaft and housing. Fig. 2 shows a common two bearing-shaft system where one bearing is free to move axially (float position) and cannot accommodate axial loading, while the other bearing is constrained axially (fixed position) and reacts the axial and radial applied loading. EFFECTIVE EARING SPREAD FLOAT POSITION FIXED POSITION Fig. 2. Typical mounting configuration for spherical roller bearings showing the position of effective load carrying centers. SHAFT ON TWO SUPPORTS Simple beam equations are used to translate the externally applied forces on a shaft into bearing reactions acting at the bearing effective centers. Following is an example calculation for a shaft with two spherical roller bearings supporting a single helical gear. Shown are equations for the case of a shaft on two supports with gear forces F t (tangential), F s (separating), and F a (thrust), an external radial load F, and an external moment M. The loads are applied at arbitrary angles ( and ) relative to the reference plane indicated in Fig.. Using the principle of superposition, the equations for vertical and horizontal reactions (F rv and F rh ) can be expanded to include any number of gears, external forces or moments. Use signs as determined from gear force equation. SHAFT ON THREE OR MORE SUPPORTS The equations of static equilibrium are insufficient to solve bearing reactions on a shaft having more than two supports. Such cases can be solved using computer programs if adequate information is available. In such problems, the deflections of the shaft, bearings and housings affect the distribution of loads. Any variance in these parameters can significantly affect bearing reactions. 26 SPHERICAL ROLLER EARING CATALOG

ENGINEERING A A LOAD RATINGS, EQUIVALENT LOADS AND EARING LIFE The basic dynamic load rating and the static load rating are commonly used for bearing selection. The basic dynamic load rating is used to estimate the life of a rotating bearing. Static load ratings are used to determine the maximum permissible load that can be applied to a non-rotating bearing. The basic philosophy of Timken is to provide the most realistic bearing rating to assist our customers in the bearing selection process. Published ratings for Timken bearings include the basic dynamic radial load rating C. This value is based on a basic rating life of one million revolutions. The basic static radial load rating is C 0. STATIC EQUIVALENT LOADS The static equivalent load rating is based on an assumed nominal clearance in both rows of rollers within the bearing, which equates to a load zone of approximately 0º. The static equivalent load is the radial load that will result in the same maximum contact stress as the applied bearing load. The load factors X 0 and Y 0 are used with the following equation to estimate the static radial equivalent load. The values of X 0 (always equal to for SRs) and Y 0 are listed in the bearing tables. P 0r = X 0 F r + Y 0 F a STATIC LOAD RATING The basic static radial load rating and thrust load rating for Timken bearings are based on a maximum contact stress within a non-rotating bearing of 4000 Mpa (80 ksi) at the center of contact on the most heavily loaded roller. The 4000 Mpa (80 ksi) stress levels may cause visible light rinell marks on the bearing raceways. This degree of marking will not have a measurable effect on fatigue life when the bearing is subsequently rotating under a lower application load. If sound, vibration or torque is critical, or if a pronounced shock load is present, a lower load limit should be applied. For more information on selecting a bearing for static load conditions, consult your Timken representative. MAXIMUM CONTACT STRESS For all spherical roller bearings, the maximum contact stress can be approximated using the static equivalent load and the static rating. 0 ( C 0 ) 0 ( C 0 ) Where: 0 = maximum contact stress P 0 = radial equivalent load = static load rating C 0 0 0 EQUIVALENT DYNAMIC RADIAL EARING LOADS (P r ) The basic dynamic radial load rating, C, is assumed to be the radial load carrying capacity with a 80º load zone in the bearing. The dynamic equivalent radial load is defined as a single radial load that, if applied to the bearing, will result in the same life as the combined loading under which the bearing operates. To calculate the L 0 life, it is necessary to calculate a dynamic equivalent radial load, designated by P r. P r = XF r + YF a Where: P r = Dynamic Equivalent Radial Load F r = Applied Radial Load F a = Applied Axial Load X = Dynamic Radial Load Factor Y = Dynamic Axial Load Factor For spherical roller bearings, the values of X and Y are dependent on the amount of the axial load. Calculate the ratio of the axial load to the radial load. Compare this ratio to the e value for the bearing. Note that values for e, X, and Y are available in the bearing tables. 28 SPHERICAL ROLLER EARING CATALOG

ENGINEERING LOAD RATINGS, EQUIVALENT LOADS AND EARING LIFE- continued MINIMUM EARING LOAD EARING LIFE EQUATIONS Slippage can occur if loads are too light and can cause damage Traditionally, the L 0 life has been calculated as follows for to the bearings. The minimum load for radial spherical roller bearings under radial or combined loading where the dynamic bearings is P r /C = 0.04 (P r is the dynamic equivalent radial load equivalent radial load (P r ) has been determined: and C the basic dynamic load rating). EARING LIFE Many different performance criteria exist that dictate how a bearing should be selected. These include bearing fatigue life, rotational precision, power requirements, temperature limits, speed capabilities, sound, etc. This section deals primarily with bearing life as related to material-associated fatigue. earing life is defined as the length of time, or number of revolutions, until a fatigue spall of 6 mm 2 (0.0 in. 2 ) develops. Since metal fatigue is a statistical phenomenon, the life of an individual bearing is impossible to precisely predetermine. earings that may appear to be identical can exhibit considerable life scatter when tested under identical conditions. Thus it is necessary to base life predictions on a statistical evaluation of a large number of bearings operating under similar conditions. The Weibull distribution function is commonly used to predict life of a population of bearings = 0 C / ( P r ) (x0 6 ) (revolutions) or, 0 C / x0 = 6 (hours) ( P r ) ( 60n ) With increased emphasis on the relationship between the reference conditions and the actual environment in which the bearing operates in the machine, the traditional life equations have been expanded to include certain additional variables that affect bearing performance. The approach whereby these factors are considered in the bearing analysis and selection, has been termed earing Systems Analysis (SA). A RATING LIFE Rating life (L 0 ) is the life that 90 percent of a group of apparently identical bearings will complete or exceed before a fatigue spall develops. The L 0 life also is associated with 90 percent reliability for a single bearing under a certain load. The ISO/AMA expanded bearing life equation is: L 0a = a a a L 2 0 Where: a = Reliability Life Factor a = Material Life Factor 2 = Operating Condition Life Factor (to be specified by the manufacturer) a The Timken expanded bearing life equation is: L 0a = a a 2 a d a k a l a m a p Where: a = Reliability Life Factor a = Material Life Factor 2 a = Debris Life Factor d a = Load Zone Life Factor k a = Lubrication Life Factor l a = Misalignment Life Factor m = Low Load Life Factor a p ( ) 0 / C P r (x0 6 ) SPHERICAL ROLLER EARING CATALOG 29

If 90 (90 percent reliability) is substituted for R in the above equation, a =. For R = 99 (99 percent reliability), a = 0.2. Table 6 lists the reliability factor for commonly used reliability values. R (percent) L n a 90 L 0.00 9 L 0.64 96 L 4 0. 97 L 0.47 98 L 2 0.7 99 L 0.2 99. L 0. 0.7 99.9 L 0. 0.09 Table 6. Reliability life factor. Note that the equation for reliability adjustment assumes there is a short minimum life below which the probability of bearing damage is minimal (e.g., zero probability of bearing damage producing a short life). Extensive bearing fatigue life testing has shown the minimum life, below which the probability of bearing damage is negligible, can be larger than shown above. For a more accurate prediction of bearing lives at high levels of reliability, consult your Timken representative. DERIS LIFE FACTOR (a d ) Debris in a lubrication system reduces the life of a roller bearing by creating indentations on the contacting surfaces, leading to stress risers. The Timken life rating equations were developed based on test data obtained with 40 μm oil filtration and measured ISO cleanliness levels of approximately /2, which is typical of cleanliness levels found in normal industrial machinery. When more or less debris is present within the system, the fatigue life predictions can be adjusted according to the measured or expected lubricant cleanliness level to more accurately reflect the expected bearing performance. As opposed to determining the debris life factor based on filtration and cleanliness levels, a Debris Signature Analysis can be performed for more accurate bearing performance predictions. The Debris Signature Analysis is a process for determining the effects of the actual debris present in your system on the bearing performance. The typical way this occurs is through measurements of dented/bruised surfaces on actual bearings run in a given application. This type of analysis can be beneficial because different types of debris cause differing levels of performance, even when they are of the same size and amount in the lubricant. Soft, ductile particles can cause less performance degradation than hard, brittle particles. Hard, ductile particles are typically most detrimental to bearing life. rittle particles can break down, thus not affecting performance to as large a degree as hard, ductile particles. For more information on Debris Signature Analysis or the availability of debris resistant bearings for your application, consult your Timken representative. ISOMETRIC VIEW MATERIAL LIFE FACTOR (a 2 ) The life adjustment factor for bearing material (a 2 ) for standard Timken bearings manufactured from bearing quality steel is.0. earings also are manufactured from premium steels, containing fewer and smaller inclusion impurities than standard steels and providing the benefit of extending bearing fatigue life (e.g., Duraspexx ). Application of the material life factor requires that fatigue life is limited by nonmetallic inclusions, contact stresses are approximately less than 2400 Mpa (0 ksi), and adequate lubrication is provided. It is important to note that improvements in material cannot offset poor lubrication in an operating bearing system.

Using the dynamic equivalent load (P r ) instead of the applied radial load (F r ) in the equation for L 0a roughly approximates the load zone factor for combined loading only. If a more accurate assessment of the load zone adjusted life is necessary (e.g., including the effects of internal clearance or fitting practice), consult your Timken representative. Note: The a l maximum is 2.88 for all bearings. The a l minimum is 0.200 for case carburized bearings and 0.26 for through hardened bearings. A lubricant contamination factor is not included in the lubrication factor because Timken endurance tests are typically run with a 40 μm filter to provide a realistic level of lubricant cleanliness for most applications. GEOMETRY FACTOR (C g ) C g is given for most part numbers in the bearing tables. The geometry factor also includes the material effects and load zone considerations, as these also are inherent to the bearing design. However, it should be noted that the primary effect of the load zone is on roller load distributions and contact stresses within the bearing, which are not quantified in the lubrication factor. Refer to the previous section load Zone Life Factor (a k ) for more information. Note that the geometry factor (C g ) factor is not applicable to our Duraspexx product.

ENGINEERING LOAD RATINGS, EQUIVALENT LOADS AND EARING LIFE- continued GREASE LURICATION FACTOR (C gr ) For grease lubrication, the EHL lubrication film becomes depleted of oil over time and is reduced in thickness. Consequently, a reduction factor (C gr ) should be used to adjust for this effect. C gr = 0.79 MISALIGNMENT LIFE FACTOR (a m ) The effect of bearing life depends on the magnitude of the angle of misalignment, internal bearing geometry and the applied loads. The misalignment life factor for spherical bearings is equal to one, a m =, due to its self-aligning capabilities. The allowable misalignment in a spherical roller bearing is between degree and 2. degrees, depending upon the series of the bearing as detailed in Table 7. Life will be reduced if these limits are exceeded due to roller-raceway contact truncation. LOW-LOAD LIFE FACTOR (a p ) earing life tests at the Timken Technology Center have shown greatly extended bearing fatigue life performance is achievable when the bearing contact stresses are low and the lubricant film is sufficient to fully separate the micro-scale textures of the contacting surfaces. Mating the test data with sophisticated computer programs for predicting bearing performance, Timken engineers have developed a low-load factor for use in the catalog to predict the life increase expected when operating under low bearing loads. Fig. 9 shows the low-load factor (a p ) as a function of the lubricant life factor (a l ) and the ratio of bearing dynamic rating to the bearing equivalent load.

ENGINEERING A A MOUNTING DESIGNS Correct bearing mounting and fitting practices are key components of proper bearing setting. Setting is the amount of clearance or interference within a mounted bearing. earing internal clearance is affected by the tightness of the fit to the inner and outer races. Proper bearing setting is crucial to bearing life and performance. Although clearance is required for most mounted bearings, application dependent factors include load, speed, bearing position, installation method, materials of construction, runout accuracy, thermal considerations, hoop stress, and shaft and housing design. This section provides tables and discussion to aid in selection of the proper bearing mounting and fitting procedures to optimize performance in general applications. For special applications, please consult your Timken representative. RADIAL INTERNAL CLEARANCE (RIC) Timken bearing RIC allows a tight fit, with sufficient internal clearance after installation for normal operating conditions. Table lists the standard RIC ranges for Timken spherical roller bearings with cylindrical and tapered bores. Spherical roller bearings with tapered bore (K) require a slightly greater interference fit on the shaft than a cylindrical bore bearing. The effect of this greater interference fit is a reduction of RIC. For tapered bore bearings, it is critical to select the RIC that allows for this reduction. Several factors influence RIC reduction. Inner rings pressed into solid steel shafts expand approximately 80 percent of the interference fit. Outer rings pressed into steel or cast iron housings reduce RIC by about 60 percent of the interference fit. For RIC reduction on hollow shafts or non-steel materials consult your local Timken representative. Timken bearings are supplied with NORMAL RIC, unless otherwise specified. The desired RIC code must be added to the bearing number, FOLLOWING ALL OTHER SUFFIXES. Min./Max. values for each RIC are shown in the two adjacent columns directly beneath the selected RIC. Each single column represents a boundary between adjacent RICs. For example, the minimum values shown for C are also the maximum values for C4; minimum values for C4 are also the maximum values for C, etc. EARING ENDPLAY In certain applications such as vane pumps, rubber mill rotor shafts or where it is necessary to take up axial expansion within the bearing, knowledge of the bearing endplay relationship to mounted radial internal clearance may be required. Table 0 shows the ratio of approximate endplay to radial internal clearance in spherical roller bearings. Example: 2220CJWC bearing has a radial internal clearance of.002 after installation. The total endplay would be approximately.0086 in. (±.004 from center). Series Endplay RIC 9 8.7 0 7.0 22..0 40 4.8 2 4.4 2 4. 4 4.2.9 Table 0.

ENGINEERING A A MOUNTING DESIGNS - continued EXAMPLE # Calculating RIC Reduction Using a Spherical Roller earing with Tapered ore Given bearing number 2228K C (40 mm bore with C clearance) is to be mounted on a tapered shaft. Using a set of feeler gauges, RIC is found to be RIC = 0.78 mm (0.007 in.) Suggested Reduction of RIC Due to Installation = 0.064 to 0.089 mm (0.002 in. to 0.00 in.), found in chart on page. Calculate the clearance after mounting 0.78 mm - 0.076 mm = 0.02 mm or 0.007 in. - 0.00 in. = 0.004 in. Mounting spherical roller bearing. Note: For this example, the value of 0.076 mm (0.00 in.) was obtained by taking the mid-range value of the upper and lower limits found in the table on page. Therefore, the locknut should be tightened until RIC reaches 0.02 mm (0.004 in.). It should also be noted that the value obtained by reading the Suggested RIC after Installation directly from the table is 0.06 mm (0.0022 in.). This differs from the value calculated in the above example. The value taken directly from the table is provided as a minimum value. It is not suggested to use a calculated value that falls below this minimum. 2 SPHERICAL ROLLER EARING CATALOG

MOUNTING DESIGNS - continued EXAMPLE #2 Calculating RIC Reduction Using a Spherical Roller earing with Cylindrical ore Observations: earing 2220YM, nominal 0 mm (.09 in.) bore and 270 mm (0.6299 in.) O.D., standard class, operating at 200 RPM. Float bearing position so the stationary O.D. should be free to move in housing, or loose fit. With shaft/inner ring rotation and the moderate loading 0.09C, the bore should be tight fit. We can use the nominal fit charts on page (Shaft Fit) and 6 (Housing Fit) to help guide our ISO fit selection. Shaft Fit (page ) at 0 mm ore: ISO p6 From the shaft fit chart at 0 mm nominal bore at p6 (page 40), the shaft tolerance is Nominal +0.04 to +0.068 mm (+0.007 to +0.0027 in.). Therefore we have the following bore range: Max. Shaft = 0.068 mm (.09 in.) Min. Shaft = 0.04 mm (.094 in.) This yields a Shaft Fit: Min. Fit = Min. Shaft Max. ore = 0.04 = 0.04 mm (0.007 in.) Tight Max. Fit = Max. Shaft Min. ore = 0.068 49.07 = 0.09 mm (0.007 in.) Tight Housing Fit (page 6) at 270 mm O.D.: ISO H8 From the housing fit chart at 270 mm nominal O.D. at H8 (page 4), the housing bore tolerance is Nominal + to +0.08 mm (+ in., +0.002 in.). Therefore we have the following bore range: Max. Housing ore = 270.08 mm (0.6 in.) Min. Housing ore = 27 mm (0.6299 in.) This yields an O.D. Fit: Min. Fit = Min. Housing ore Max. O.D. = 27 27 = mm ( in.) Loose Max. Fit = Max. Housing ore Min O.D. = 270.08 269.96 = 0.6 mm (0.0046 in.) Loose ENGINEERING DETERMINING PROPER RIC For the primary selection of radial internal clearance, RIC, the major parameters are the bearing speed and the fits. For our example, we know that the shaft fit is 0.04 mm (0.007 in.) tight to 0.09 mm (0.007 in.) tight. We know the housing fit is line to 0.6 mm (0.0046 in.) loose. We also know that the bearing speed is 200 RPM or 60 percent of the speed rating. As a general rule of thumb, we bump the clearance up due to operating speeds that exceed 70% of the speed rating, due to concerns over internal heat generation and thermal growth. In this case, we are at 60 percent of the speed rating, so normal clearance, ISO C0 or C Normal, can be selected. Observing the RIC chart on page, we find for 0 mm nominal bore at C Normal the RIC will be 0.0 mm to 0.70 mm (0.004 in. to 0.0067 in.). We also note that the minimum recommended RIC (installed) is 0.06 mm (0.0022 in.). Also from page, we note that we get an approximate reduction of RIC that is 80 percent of interference fit on a solid shaft and 60 percent of the OD interference fit in a steel or cast iron housing. Since we have a loose housing fit, there will be no RIC reduction from that fit. Shaft Fit RIC Reductions and Clearance: 0.04 mm (0.007 in.) tight = 0.04 mm (0.004 in.) RIC reduction 0.09 mm (0.007 in.) tight = 0.074 mm (0.000 in.) RIC reduction Max. Clearance = Max. RIC Min. Fit Reduction = 0.70 0.04 = 0.6 mm (0.004 in.) Min. Clearance = Min. RIC Max. Fit Reduction = 0.0 0.074 = 0.06 mm (0.004 in.)

ENGINEERING A A MOUNTING DESIGNS - continued EARING SHAFT AND HOUSING SEATS Geometry Under load, spherical roller bearings typically conform to the shape of the shaft and housing seats into which they are mounted. For example, seats of inner rings and/or outer rings that are machined out of round will cause the bearing rings to take this form and therefore impart error motion into the shaft. Therefore, the shaft and housing seats should be machined to at least the same precision as the bearing bore and O.D. respectively. Tolerances for the bearing bore and O.D. are listed in Tables 8 and 9. SURFACE FINISHES STANDARD EARINGS For industrial applications, please refer to the following guidelines: Shaft O.D.

For housings of aluminum / magnesium, tolerances generally are selected which give a slightly tighter fit than those given in the table. NON FERROUS HOUSINGS Care should be taken when pressing outer rings into aluminum or magnesium housings to avoid metal pick up. This may result in unsatisfactory fits, backing, and alignment from debris trapped between the outer rings and backing shoulder.

This may cause damage to machinery in which the bearing is a component. If interference fits are either greater or less than those specified, the mounted bearing setting will be other than intended. 6 SPHERICAL ROLLER EARING CATALOG

LURICATION AND SEALS LURICATION To help maintain a rolling bearing s anti-friction characteristics, lubrication is needed to: Minimize rolling resistance due to deformation of the rolling elements and raceway under load by separating the mating surfaces. Minimize sliding friction occurring between rolling elements, raceways and cage. Transfer heat (with oil lubrication). Protect from corrosion and, with grease lubrication, from contaminant ingress. Modern lubricants do this very effectively, although in many applications the means by which they accomplish this are extremely complex and not completely understood. ecause the principles involved with lubricating rolling element bearings are complex and do not have to be known to employ lubricants successfully, this discussion will stress the practical rather than the theoretical aspects of lubrication. LURICATION SELECTION The wide range of bearing types and operating conditions precludes any simple, all-inclusive statement or guideline for the selection of the proper lubricant. At the design level, the first consideration is whether oil or grease is best for the particular operation. The advantages of oil and grease are outlined in the table below. When heat must be carried away from the bearing, oil must be used. It is nearly always preferred for very high speed applications. For speed ratings of grease and oil-lubricated bearings, refer to the section entitled Speed, Heat and Torque. Table. OIL Carries heat away from the bearings ADVANTAGES OF OIL AND GREASE Carries away moisture and particulate matter Easily controlled lubrication GREASE Simplifies seal design and acts as a sealant Permits prelubrication of sealed or shielded bearings Generally requires less frequent lubrication LURICANT ADDITIVES Additives are materials, usually chemicals, that improve specific properties when added to lubricants. Additives, when properly formulated into a lubricant, can increase lubricant life, provide greater resistance to corrosion, increase load-carrying capacity and enhance other properties. Additives are very complex and should not be added indiscriminately to lubricants as a cure-all for lubrication problems. The more common lubricant additives include: Oxidation inhibitors for increasing lubricant service life. Rust or corrosion inhibitors to protect surfaces from rust or corrosion. ENGINEERING Demulsifiers to promote oil and water separation. Viscosity-index improvers to decrease viscosity sensitivity to temperature change. Pour-point depressants to lower the pouring point at low temperatures. Lubricity agents to modify friction. Antiwear agents to retard wear. Extreme pressure (EP) additives to prevent scoring under boundary-lubrication conditions. Detergents and dispersants to maintain cleanliness. Antifoam agents to reduce foam. Tackiness agents to improve adhesive properties. Inorganic additives such as molybdenum disulphide, graphite, and zinc oxide are sometimes included in lubricants. In most roller bearing applications, inorganic additives are of no significant benefit; conversely, as long as the concentration is low and the particle size small, they are not harmful. Recently, the effects of lubricant chemistry on bearing life (as opposed to the purely physical characteristics) have received much emphasis. Rust, oxidation, extreme pressure and anti-wear additive packages are widely used in engine and gear oils. Fatigue testing has shown these additives may, depending on their chemical formulation, concentration and operating temperature, have a positive or negative impact on bearing life. Consult your Timken representative for more information regarding lubricant additives. GUIDANCE FOR OIL/GREASE SELECTION Oil Lubrication Oils used for bearing lubrication should be high-quality, nonoxidizing mineral oils or synthetic oils with similar properties. Selection of the proper type of oils depends on bearing speed, load, operating temperature and method of lubrication. Some features and advantages of oil lubrication, in addition to the above, are as follows: Oil is a better lubricant for high speeds or high temperatures. It can be cooled to help reduce bearing temperature. With oil, it is easier to handle and control the amount of lubricant reaching the bearing. It is harder to retain in the bearing. Lubricant losses may be higher than with grease. As a liquid, oil can be introduced to the bearing in many ways, such as drip-feed, wick-feed, pressurized circulating systems, oil-bath or air-oil mist. Each is suited to certain types of applications. Oil is easier to keep clean for recirculating systems. Oil may be introduced to the bearing housing in many ways. A SPHERICAL ROLLER EARING CATALOG 7

ENGINEERING A A LURICATION AND SEALS - continued The most common systems are: Oil ath. The housing is designed to provide a sump through which the rolling elements of the bearing will pass. Generally, the oil level should be no higher than the center point of the lowest rolling element. If speed is high, lower oil levels should be used to reduce churning. Gages or controlled elevation drains are used to achieve and maintain the proper oil level. Circulating System. This system has the advantages of: An adequate supply of oil for both cooling and lubrication. Metered control of the quantity of oil delivered to each bearing. Removal of contaminants and moisture from the bearing by flushing action. Suitability for multiple bearing installations. Large reservoir, which reduces deterioration. Increased lubricant life provides economic efficiency. Incorporation of oil filtering devices. Positive control to deliver the lubricant where needed. A typical circulating oil system consists of an oil reservoir, pump, piping and filter. A cooler may be required. Oil-Mist Lubrication. Oil-mist lubrication systems are used in high-speed, continuous operation applications. This system permits close control of the amount of lubricant reaching the bearings. The oil may be metered, atomized by compressed air and mixed with air, or it may be picked up from a reservoir using a venturi effect. In any case, the air is filtered and supplied under sufficient pressure to assure adequate lubrication of the bearings. Control of this type of lubrication system is accomplished by monitoring the operating temperatures of the bearings being lubricated. The continuous passage of the pressurized air and oil through the labyrinth seals used in the system prevents the entrance of contaminants from the atmosphere to the system. The successful operation of this type of system is based upon the following factors: proper location of the lubricant entry ports in relation to the bearings being lubricated, avoidance of excessive pressure drops across void spaces within the system, the proper air pressure and oil quantity ratio to suit the particular application, and the adequate exhaust of the air-oil mist after lubrication has been accomplished. To ensure wetting of the bearings and to prevent possible damage to the rolling elements and races, it is imperative that the oil mist system be turned on for several minutes before the equipment is started. The importance of wetting the bearing before starting cannot be overstated and has particular significance for equipment that has been idled for extended periods of time. OIL LURICATION GUIDELINES Oil Lubrication Lubricating oils are commercially available in many forms for automotive, industrial, aircraft and other uses. Oils are classified as either petroleum types (refined from crude oil) or synthetic types (produced by chemical synthesis). Petroleum Oils Petroleum oils are used for nearly all oil-lubricated applications of Timken bearings. These oils have physical and chemical properties that can help in the selection of the correct oil for any bearing application. Synthetic Oils Synthetic oils cover a broad range of categories and include polyalphaolefins, silicones, polyglycols, and various esters. In general, synthetic oils are less prone to oxidation and can operate at extreme hot or cold temperatures. physical properties, such as pressure-viscosity coefficients, tend to vary between oil types and caution should be used when making oil selections. The polyalphaolefins (PAO) have a hydrocarbon chemistry, which parallel petroleum oil both in their chemical structures and pressure-viscosity coefficients. Therefore, PAO oil is mostly used in the oil-lubricated applications of Timken bearings when severe temperature environments (hot and cold) are encountered or when extended lubricant life is required. The silicone, ester and polyglycol oils have an oxygen based chemistry that is structurally quite different from petroleum oils and PAO oils. This difference has a profound effect on its physical properties where pressureviscosity coefficents can be lower compared to mineral and PAO oils. This means that these types of synthetic oils may actually generate a smaller EHD film thickness than a mineral or PAO oil of equal viscosity at operating temperature. Reductions in bearing fatigue life and increases in bearing wear could result from this reduction of lubricant film thickness. Selection of Oils The selection of oil viscosity for any bearing application requires consideration of several factors: load, speed, internal clearance, type of oil, and environmental factors. Since viscosity varies inversely with temperature, a viscosity value must always be stated with the temperature at which it was determined. High viscosity oil is used for low-speed or high-ambient temperature applications. Low viscosity oil is used for high-speed or low-ambient temperature applications. 8 SPHERICAL ROLLER EARING CATALOG

LURICATION AND SEALS - continued CLASSIFICATION There are several classifications of oils based on viscosity grades. The most familiar are the Society of Automotive Engineers (SAE) classifications for automotive engine and gear oils. The American Society for Testing and Materials (ASTM) and the International Organization for Standardization (ISO) have adopted standard viscosity grades for industrial fluids. Fig. 2 shows the viscosity comparisons of ISO/ASTM with SAE classification systems at 40 C (04 F). Fig. 2.

Industrial EP gear oils should be composed of a highly refined petroleum oil-based stock plus appropriate inhibitors and additives. They should not contain materials that are corrosive or abrasive to bearings. The inhibitors should provide long-term protection from oxidation and protect the bearing from corrosion in the presence of moisture. The oils should resist foaming in service and have good water separation properties. An EP additive protects against scoring under boundary-lubrication conditions. The viscosity grades suggested represent a wide range. High temperature and/ or slow-speed applications generally require the higher viscosity grades. Low temperatures and/or high speeds require the use of lower viscosity grades. SPHERICAL ROLLER EARING CATALOG 9 A

ENGINEERING A A LURICATION AND SEALS - continued LURICATING GREASES Definition According to the ASTM definition, lubricating grease is a solid to semi-fluid product of the dispersion of a thickening agent in a liquid lubricant; other ingredients imparting special properties may be included. If this definition were applied in the manner a chemist would use to illustrate a chemical reaction, the composition of a grease could be described by the formula below.

At this time, there is no known universal anti-friction bearing grease. Each individual grease has certain limiting properties and characteristics. Synthetic lubricating fluids, such as esters, organic esters and silicones, are used with conventional thickeners or chemical additives to provide greases capable of performing over an extremely wide range of temperatures, from as low as -7 C (-00 F) to a high of 288 C (0 F). The successful use of lubricating grease in roller bearings depends on the physical and chemical properties of the lubricant pertaining to the bearing, its application, installation and general environmental factors. ecause the choice of a lubricating grease for a particular bearing under certain service conditions is often difficult to make, your Timken representative should be consulted for proper suggestions. Grease Lubrication The simplest lubrication system for any bearing application is grease. Conventionally, greases used in Timken bearing applications are petroleum oils of some specific viscosity that are thickened to the desired consistency by some form of metallic soap. Greases are available in many soap types such as sodium, calcium, lithium, calcium-complex and aluminium-complex. Organic and inorganic type non-soap thickeners also are used in some products. Soap Type Calcium greases have good water resistance. Sodium greases generally have good stability and will operate at higher temperatures, but they absorb water and cannot be used where moisture is present. Lithium, calcium-complex and aluminiumcomplex greases generally combine the higher temperature properties and stability of sodium grease with the water resistance of calcium grease. These greases are often referred to as multipurpose greases since they combine the two most important lubricant advantages into one product. Characteristics and Operating Environments Listed below are the general characteristics of prominent roller bearing greases.

NOTE: The properties of a grease may vary considerably depending on the particular oil, thickener and additives used in the formulation. ** Continuous operation with no relubrication. Depending upon the formulation the service limits may vary. The usable limit can be extended significantly with relubrication. Polyurea as a thickener for lubricating fluids is one of the most significant lubrication developments in more than 0 years. Polyurea grease performance in a wide range of bearing applications is outstanding, and in a relatively short time it has gained acceptance as a factory-packed lubricant for ball bearings. Consistency Greases may vary in consistency from semifluids hardly thicker than a viscous oil, to solid grades almost as hard as a soft wood. Consistency is measured by a pentrometer, in which a standard weighted cone is dropped into the grease. The distance the cone penetrates (measured in tenths of a millimeter in a specific time) is the penetration number. The National Lubricating Grease Institute (N.L.G.I.) classification of grease consistency is shown below: Table 20. NLGI Grease Grades Penetration Number 0-8 0-40 2 26-29 220-20 4 7-20 0-60 6 8- Grease consistency is not fixed; it normally becomes softer when sheared or worked. In the laboratory this working is accomplished by forcing a perforated plate up and down through a closed container of grease. This working does not compare with the violent shearing action that takes place in a ball bearing and does not necessarily correlate with actual performance. 60 SPHERICAL ROLLER EARING CATALOG

LURICATION AND SEALS - continued Low Temperatures Starting torque in a grease-lubricated bearing at low temperatures can be critical. Some greases may function adequately as long as the bearing is operating, but resistance to initial movement is such that the starting torque is excessive. In certain smaller machines, starting is an impossibility when very cold. Under such operating circumstances, the greases containing low-temperature characteristic oils are generally required. If the operating temperature range is wide, synthetic fluid greases offer definite advantages. Greases are available to provide very low starting and running torque at temperatures as low as -7 C (-00 F). In certain instances, these greases perform better in this respect than oil. An important point concerning lubricating greases is that the starting torque is not necessarily a function of the consistency or the channel properties of the grease. It appears to be more a function of the individual properties of the particular grease and is difficult to measure. Experience alone will indicate whether one grease is superior to another. High Temperatures The high temperature limit for modern grease is generally a function of the thermal and oxidation stability of the fluid and the effectiveness of the oxidation inhibitors. Fig. 2 was prepared using military-specification greases to illustrate the thermal limitations of mineral oil, ester, silicone, and flouronated ether greases. The limits as shown apply only to prelubricated bearings or to applications where relubrication is not possible. Where provisions have been made for relubrication, the temperature limits may be extended provided the interval between cycles is reduced accordingly. A rule of thumb, developed from years of testing greaselubricated bearings, indicates that grease life is halved for every 0 C (8 F) increase in temperature. For example, if a particular grease is providing 2000 hours of life at 90 C (94 F) raising the temperature to 00 C (22 F) reduction in life to approximately 000 hours would result. On the other hand, 4000 hours could be expected by lowering the temperature to 80 C (76 F). It becomes obvious that the reactions started by the normal reaction of lubricant with oxygen increases rapidly at higher temperatures. The lubricants undergo a series of chemical reactions that ultimately result in the development of viscous or hard residues that interfere with the operation of the bearing. Thermal stability, oxidation resistance, and temperature limitations must be considered when selecting greases for hightemperature applications. In non-relubricatable applications, highly refined mineral oils or chemically stable synthetic fluids are required as the oil component of greases for operation at temperatures above 2 C (20 F).

LURICATION AND SEALS - continued WET CONDITIONS Water and moisture can be particularly conducive to bearing damage. Lubricating greases may provide a measure of protection from this contamination. Certain greases - the calcium, lithium and non-soap type, for example - are highly water-resistant. However, these greases exhibit poor rust preventative characteristics unless properly inhibited. Sodium-soap greases emulsify with small amounts of moisture that may be present and prevent the moisture from coming in contact with the bearing surfaces. In certain applications, this characteristic may be advantageous; however, emulsions are generally considered undesirable. Many bearing applications require lubricants with special properties or lubricants formulated specifically for certain environments, such as: Friction Oxidation (Fretting Corrosion) Chemical and Solvent Resistance Food Handling Quiet Running Space and/or Vacuum Electrical Conductivity For assistance with these or other areas requiring special lubricants, consult your Timken representative. CONTAMINATION Abrasive Particles When roller bearings operate in a clean environment, the primary cause of damage is the eventual fatigue of the surfaces where rolling contact occurs. However, when particle contamination enters the bearing system, it is likely to cause damage such as bruising, which can shorten bearing life. When dirt from the environment or metallic wear debris from some component in the application is allowed to contaminate the lubricant, wear can become the predominant cause of bearing damage. If, due to particle contamination of the lubricant, bearing wear becomes significant, changes will occur to critical bearing dimensions that could adversely affect machine operation. earings operating in a contaminated lubricant exhibit a higher initial rate of wear than those not running in a contaminated lubricant. ut, with no further contaminant ingress, this wear rate quickly diminishes as the contamination particles are reduced in size as they pass through the bearing contact area during normal operation. ENGINEERING Water Either dissolved or suspended water in lubricating oils can exert a detrimental influence on bearing fatigue life. Water can cause bearing etching that also can reduce bearing fatigue life. The exact mechanism by which water lowers fatigue life is not fully understood. It has been suggested that water enters microcracks in the bearing races that are caused by repeated stress cycles. This leads to corrosion and hydrogen embrittlement in the microcracks, reducing the time required for these cracks to propagate to an unacceptable size spall. Water-base fluids such as water glycol and invert emulsions also have shown a reduction in bearing fatigue life. Although water from these sources is not the same as contamination, the results support the previous discussion concerning water-contaminated lubricants. A SPHERICAL ROLLER EARING CATALOG 6

ENGINEERING A A LURICATION AND SEALS - continued GREASES Applications and Lubricating Methods Grease lubrication is generally applicable to the following conditions, and features low-to-moderate speed applications within operating temperature limits of the grease: Easily confined in the housing. This is important in the food, textile and chemical industries. earing enclosure and seal design simplified. Improves the efficiency of external mechanical seals to give better protection to the bearing. Successfully used for integrally-sealed, prelubricated ball bearings. Advantages of Prelubricated earings Prelubricated shielded and sealed bearings are extensively used with much success in applications where: Grease might be injurious to other parts of the mechanism. Cost and space limitations preclude the use of a greasefilled housing. Housings cannot be kept free of dirt and grit, water or other contaminants. Relubrication is impossible or hazardous Prelubricated Timken bearings are prepacked with greases that have chemical and mechanical stability and have demonstrated long life characteristics in rotating bearings. Greases are filtered several times to remove all harmful material and accurately metered so that each bearing receives the proper amount of grease. GREASE LURICATIONS FOR EARING HOUSING ASSEMLIES Polyurea and lithium-based greases are normally preferred for general purpose bearing lubrication and are advantageous in high moisture applications. oth greases have good water-resistant characteristics. For temperature ranges of standard greases, see chart on page 6. The grease must be carefully selected with regard to its consistency at operating temperature. It should not exhibit thickening, separation of oil, acid formation or hardening to any marked degree. It should be smooth, non-fibrous and entirely free from chemically active ingredients. Its melting point should be considerably higher than the operating temperature. Frictional torque is influenced by the quantity and the quality of lubricant present. Excessive quantities of grease cause churning. This results in excessive temperatures, separation of the grease components, and breakdown in lubrication values. In normal speed applications, the housings should be kept approximately one-third to one-half full. Only on low-speed applications may the housing be entirely filled with grease. This method of lubrication is a safeguard against the entry of foreign matter, where sealing provisions are inadequate for exclusion of contaminants or moisture. During periods of non-operation, it is often wise to completely fill the housings with grease to protect the bearing surfaces. Prior to subsequent operation, the excess grease should be removed and the proper level restored. Applications utilizing grease lubrication should have a grease fitting and a vent at opposite ends of the housing near the top. A drain plug should be located near the bottom of the housing to allow purging of the old grease from the bearing. Relubricate at regular intervals to prevent damage to the bearing. Relubrication intervals are difficult to determine. If plant practice or experience with other applications is not available, consult your lubricant supplier. 64 SPHERICAL ROLLER EARING CATALOG

LURICATION AND SEALS - continued MULTI-PURPOSE INDUSTRIAL GREASE These are typical of greases that can be used to lubricate many Timken bearing applications in all types of standard equipment. Special consideration should be given to applications where speed, load, temperature or environmental conditions are extreme. Suggested Lithium Soap, Lithium Complex, and Calcium Sulfonate Grease Properties Thickener type Lithium Complex, or equivalent Consistency NLGI No. or No. 2 Additives Anti-wear, corrosion and oxidation inhibitors ase oil Mineral oil or synthetic Viscosity at 40 C ISO VG 0-220 Viscosity index 80 min. Pour point -8 C max. Lithium greases, Lithium Complex Greases, or Calcium Sulfonate thickened grease are suitable for most centralized, Single Point, or manual lubricated product. They should be a smooth, homogeneous and uniform, premium-quality product composed of mineral or synthetic oil, a thickener, and appropriate inhibitors. It should not contain materials that are corrosive or abrasive to roller bearings. The grease should have excellent mechanical and chemical stability. The grease should contain inhibitors to provide long-term protection against oxidation in high-performance applications and protect the bearings from corrosion in the presence of moisture. The suggested base oil viscosity covers a fairly wide range. Lower viscosity products should be used in high-speed and/or lightly loaded applications to minimize heat generation and torque. Higher viscosity products should be used in moderate- to lowspeed applications and under heavy loads to maximize lubricant film thickness. Speed ratings are listed for each size/class part number in the Spherical Roller earing section (pages 80 to 96) of the catalog. When speeds of application exceed 70% of grease speed rating, consider increasing RIC by one ISO clearance range (C Normal to C). Never mix greases (type or manufacturer). Incompatibility can inhibit proper lubrication. Table 2 on page 62 is provided as a reference for typical grease thickener compatibilities. Consult your lubricant supplier for further information for your specific requirement. For general industrial applications consider a grease that is NLGI No. or No. 2, with a ISO 0 to 220 viscosity grade. Application Considerations For higher speed applications (operating at 7 percent of the grease speed rating or more), a grease with a lighter base oil viscosity (ISO00-0) can be considered. Conversely, for lower speed applications, a grease with a heavier base oil viscosity (ISO 20-460) can be considered. For lower speed applications operating at colder start up temperatures (<0 F), consider a softer grease (NLGI grade ) with an approved EP additive. The lighter grade will allow more grease flow into the bearing contact area and the EP additive will reduce wear during startup. An ISO 460 base oil viscosity can also be considered. When lower speed applications operate at higher temperatures (>00 F), consult a local Timken sales representative. ENGINEERING Grease Fill For normal industrial applications, fill the bearing void to 70 to 00 percent full and the housing void to 0 percent full. For high speed applications, fill the bearing void to 0 to 70 percent full and the housing void to percent full. The free volume of the bearing can be estimated by first calculating the solid ring volume of the bearing. Then, weigh the bearing and divide the weight by the density of steel. This actual volume can then be subtracted from the solid ring volume. The resultant value is an estimate of the free volume of the bearing available for grease fill. When the grease volume is determined for the application, multiplying this value by the density of the grease will yield the approximate weight of the grease fill. After weighing the grease required, apply approximately 7 percent of the amount into the cage and roller assembly. The remaining amount of grease should then be applied to both inner and outer rings in equal amounts. The preservatives applied to bearing components are compatible with nearly all industrial greases: and should not be wiped or cleaned prior to packing the bearing. If in doubt, contact a local Timken sales representative. Re-Greasing Cycle The two primary considerations that determine the regreasing cycle on any application are operating temperature and sealing efficiency. Obviously, seal leakage will dictate frequent relubrication. Every attempt should be made to maintain seals at peak efficiency. Generally the higher the temperature, the more rapidly the grease oxidizes. Grease life is reduced by approximately half for every 0 C (0 F) rise in temperature. The higher the operating temperature, the more often the grease must be replenished. In most cases, experience in the specific application will dictate the frequency of lubrication.

LURICATION AND SEALS - continued SELECTING THE RIGHT SEAL When selecting the proper seal design for any Timken bearing application, it is necessary to consider the type of lubricant, the operation environment, the speed of the application and general operating conditions. Grease Lubrication - Venting In any bearing application, good design practice allows for adequate venting in case of heat generation. This is especially valid when grease lubrication is used in conjunction with contact or noncontact seals. This will also help prevent an ingress of contamination past the seals in the event that a pressure differential is created between the bearing cavity and the ambient environment. ENGINEERING Shaft Finish It is important to ensure that no spiral grooves result from machining shaft surfaces since these will tend to draw lubricant out of, or contaminant into, the bearing cavity. Plunge grinding normally produces a satisfactory surface finish. Vertical Shaft Closures - Oil Lubrication Lubricating vertical shaft bearings is a difficult problem. Normally, grease, oil mist or oil-air lubrication is used because of the simplicity. However, some high speed and/or heavy load applications will use circulating oil. This requires a very good sealing system and a suction pump to remove the oil from the bottom bearing position. A Precision triple-ring labyrinth seals are supplied with all Timken pillow blocks to exclude foreign matter and retain lubricants. The pillow block base includes extra large oil return holes at the bottom of the seal grooves to prevent leakage past the seals. For additional information on seal options not shown, contact your Timken representative. TACONITE SEALS FTV Series Flinger Taconite Seal with V-ring Combines the qualities of the face labyrinth seal and the DUSTAC seal to improve the sealing efficiency for extremely contaminated environments. The rotating flinger added to the basic design, incorporates face labyrinth grooves and compresses the O-ring in the bore. This protects against incursion of foreign matters and ensures regular pressure of the V-ring to the cartridge face. FTL Series Flinger Taconite Seal with Lip Seal The FTL seal has the same property as the FTV Series, but above the V-ring is substituted to a lip seal working directly on the Flinger Lip to prevent the shaft of any grooving. The FTV and FTL Taconite seals can be substituted in either ER or LER ring SAF pillow block series and do not require modifications to the standard housings. NOTE: Flinger Taconite seals can be substituted to ER or LER seal. Add the suffix L to the number when it is for a housing using LER Seals (e.g., TFV-L for SAF-L pillow block). LARINYTH SEALS Using labrinyth seals greatly increases the operating time between maintenance intervals of rotating equipment. Used in split pillow blocks. Endures extreme environments such as pulp and paper, chemical and mining because of its exceptional design. Two-piece labyrinth seal of Teflon PTFE fluoropolymer resin. The assembly inhibits the passage of contaminants or lubricants and prevents the components from coming apart during installation and service. Installation is simple compared to many other lip-contact type seals and is more effective in reducing lubricant loss, improving plant safety. It is also environmentally friendly. Other enefits Include: Drop-in style eliminates machining or modification to housing. Interchangeable with LER or taconite seals. Available for standard Inch and SNH pillow blocks ( / 4 in. to 8 in. shaft diameter). Minimizes lubricant leakage. Accommodates greater shaft misalignment or eccentricity.

ENGINEERING A A SPEED, HEAT AND TORQUE SPEED RATINGS There is no precise method for determining the maximum speed at which a bearing may operate. earing characteristics and features of surrounding parts, shafts, housing and other components as well as basic service conditions, are all variables dependent upon each other for continued satisfactory high-speed performance. The safe operating speed of a bearing is often limited by the temperature within the bearing, which in turn is often dependent upon the temperature surrounding the application, accuracy of the bearings, shafts, housings, auxiliary parts and the type and amount of lubricant. earings with proper internal refinements will operate at high speeds for long periods if properly installed and lubricated. Tolerance grade, cage design, and lubricant are bearings characteristics that affect speed limitations. Although the speed rating values tabulated within are based on many years of research and accumulated data, numerous applications of Timken bearings are successfully operating with speed values in excess of those tabulated. Such applications require particular consideration of proper tolerance grade, lubrication, the effect of centrifugal force on rolling elements and other factors. For further information consult your Timken representative. Conversely, under certain application conditions of load, temperature, contamination, etc., speed capabilities may be less than published within. For spherical roller bearings, the thermal speed ratings are listed in the bearing tables. These values have been determined by balancing the heat generated within the bearing with the heat dissipated from the bearing. In calculating these numbers, the following assumptions have been made: The radial load is percent of the static load rating. For oil, it is assumed to be in a bath with the fill to the middle of the lowest rolling element. For grease it is assumed a 0 percent bearing cavity fill. The oil viscosity is assumed to be 2 cst (ISO VG 2) operated at 70 C (8 F) and the grease base oil viscosity is assumed to be 22 cst operated at 70 C (8 F). The bearing and its components are at 70 C (8 F) and the bearing environment is at 20 C (68 F). The housing and shaft are steel or cast iron. The bearing rotational axis is horizontal. The outer ring is stationary and the inner ring is rotating. The bearing radial internal clearance complies with class normal and standard fits are used. The bearing does not contain seals. The bearing does not experience misalignment or axial load. The speed ratings are for reference only and can be considerably lower or higher depending on your application. Consult your Timken representative for more accurate information regarding a bearing s speed capabilities in your application. 68 SPHERICAL ROLLER EARING CATALOG

SPEED, HEAT AND TORQUE - continued OPERATING TEMPERATURES Temperature Limitations earing equilibrium temperature is not simply a question of speed. It is also dependent on the heat generation rate of all contributing heat sources, nature of the heat flow between sources, and heat dissipation rate of the system. Seals, gears, clutches, and oil supply temperature affect bearing operating temperature. Heat dissipation rate is governed by such factors as type of lubrication system; materials and masses of the shaft and housing and intimacy of contact with the bearing; and surface area and character of the fluid both inside and outside the housing. Temperature of the outer surface of the housing is not an accurate indication of bearing temperature. The inner ring temperature is often greater than the outer ring temperature and both are usually greater than the outer surface of the housing. There are temperature gradients within the bearing, with the temperature of the internal parts usually being greater than the outer surfaces. Although the temperature of the outer ring O.D., the inner ring I.D., or the oil outlet often used as an indicator of bearing temperature, it should be recognized that these are generally not the highest bearing temperatures. During transient conditions, such as at startup, bearing temperatures will often peak and then reduce to a lower level. This is due to the thermal changes taking place between the bearing, shaft and housing, causing variations in internal clearance and internal loading. Also, a new bearing will usually generate more heat until it runs in. The allowable operating temperature depends on: Equipment requirements Lubrication limitations earing material limitations Reliability requirements Each factor is an area of increasing concern as operating temperatures rise. The equipment designer must decide how operating temperature will affect the performance of the equipment being designed. Precision machine tools, for example, can be very sensitive to thermal expansions. In many cases it is important that the temperature rise over ambient be minimized and held to 20 to 2 C (6 to 4 F) for some precision spindles. Most industrial equipment can operate satisfactorily with considerably higher temperature rises. thermal ratings on gear drives, for example, are based on 9 C (200 F). Some equipment such as plastic calendars and gas turbine engines operate continuously at temperatures well above 00 C (22 F). Standard bearing steels cannot maintain the desired minimum hot hardness of 8 Rc much above C (27 F). Standard Timken spherical roller bearings are dimensionally stabilized up to 200 C (92 F). Upon request, the bearings can be ordered with dimensional stabilization up to 20 C (482 F) or 00 C (72 F). ENGINEERING Consult your Timken representative for availability of S, S2, S suffixes or high-temperature steels in specific part numbers and applications. Although bearings can operate satisfactorily at higher temperatures, an upper temperature limit of 80 to 9 C (76 to 20 F) is usually more practical for small, high volume equipment where prototype testing is possible. Higher operating temperatures increase the risk of damage from some unforeseen, transient condition. If prototype testing is not practical, an upper design limit of 80 C (76 F) is appropriate, unless prior experience on similar equipment suggests otherwise. History on some machines operating at higher temperatures, such as high-speed rolling mills, offers good background data for establishing limits on new, similar machines. Obviously none of the above examples of equipment, lubricant or bearing material limitations are single point limitations, but rather areas of gradually increasing concern. It is the responsibility of the equipment designer to weigh all relevant factors and make the final determination of what operating temperature is satisfactory for a particular machine. Suggested materials for use in rings and rollers at various operating temperatures are listed together with data on chemical composition, hardness and dimensional stability. A temperature of 427 C (800 F) is generally the top limit for successful bearing operation using steels. Above 427 C (800 F), or below where lubricant is not permitted, cast or wrought cobalt alloys are generally used. Although chosen primarily for their good retention of physical properties, they also possess good oxidation resistance at elevated temperatures.

SPEED, HEAT AND TORQUE - continued HEAT GENERATION AND DISSIPATION One of the major benefits of oil-lubricated systems is that the heat generated by the bearings is carried away by the circulating oil and dissipated through the system. Heat Generation Under normal operating conditions, most of the torque and heat generated by the bearing is due to the elastohydrodynamic losses at the roller/race contacts. The following equation is used to calculate the heat generated by the bearing: =k 4 n M Q gen Where: Q gen = generated heat (W or TU/min) M = running torque N-m or lbf-in n = rotational speed (RPM) k 4 = Dimensional factor to calculate heat generation rate = 0.0 for Qgen in W when M in N-m = 6.7 x 0-4 for Qgen in TU/min when M in lbf-in Heat Dissipation The heat dissipation rate of a bearing system is affected by many factors. The modes of heat transfer need to be considered. Major heat transfer modes in most systems are conduction through the housing walls, convection at the inside and outside surfaces of the housing, and convection by the circulating lubricant. In many applications, overall heat dissipation can be divided into two categories: heat removed by circulating oil and heat removed through the housing. Heat Dissipation by Circulating Oil Heat dissipated by a circulating oil system is: ENGINEERING Other Considerations Until now, temperature limitation has been discussed in reference to metallurgical considerations. However, installations which operate at high temperatures for extended periods may lose the quality of shaft and housing fits. Carefully machined and heat-treated shafts and housings will minimize trouble from this source. In some applications the internal clearance of bearings may be partially absorbed. For example, during the first few seconds of rotation, a massive housing may keep the outer race cooler than the inner race and rolling elements even if the housing is already at some elevated temperature. Also, during heat soakback when rotation stops, heat may flow back to the bearing along the shaft. If, while stationary, the effects of heat soakback more than remove the radial internal clearance, radial brinell of the races may occur, and the bearing will be rough during subsequent rotation. earings with extra internal looseness may be required to compensate for the above conditions.

SPHERICAL ROLLER EARINGS A INTRODUCTION The Timken self-aligning spherical roller bearing is a combination radial and thrust bearing, designed to operate even if shaft and housing are, or become, misaligned under load. This high-capacity bearing is the favored choice when conditions include heavy loads, plus difficulties in establishing or maintaining housing alignment, or when shaft deflection can be expected. Shaft deflections and housing distortions, caused by shock or heavy loads that lead to misalignment, are compensated with internal self-alignment of the bearing elements during operation. Edge loading of rollers, a condition that limits service life on other types of bearings, does not develop in spherical roller bearings. Optimum bearing capacity can often be realized with up to ± 2 degrees of misalignment, depending on the size and series of bearing selected. EARING TYPES CJ YM YM Higher load ratings for longer life. Tapered ore with Adapter Sleeve Incorporates advanced features and precision-machined, roller-riding, one-piece brass cage. Suited for severe conditions of use.

TAPERED ORE EARINGS WITH ADAPTER SLEEVES SNW adapter assemblies consist of a sleeve and Locknut. Lockwashers are available for shaft mounting of tapered bore K bearings. Description of shaft mounting techniques for tapered bore bearings with adapter sleeves are found on page 04. The spherical roller bearing s inherent compensation for misalignment offers the designer the opportunity to use weldments for housing frames instead of complex castings, eliminating high-cost machining operations. Even when castings may be preferred, bore alignment is less critical if spherical roller bearings are specified. Unit design and construction also make the spherical roller bearing convenient to handle during installation or maintenance. Several types of radial spherical roller bearings include CJ, YM, YM, YMD, and VCSJ types. earings are made to ISO Class 0 tolerances. Life calculations, shaft and housing fits, internal clearances, tolerances and other technical data for these bearings are found in the engineering section of this catalog.

Spherical Roller earings MOUNTING PROCEDURES Depending on the size of the bearing and the application, there are different methods for mounting roller bearings. In all methods, certain basic rules must be followed. CLEANLINESS Choose a clean environment, free from dust and moisture. The installer should make every effort to ensure cleanliness by use of protective screens and clean cloths. PLAN THE WORK Know in advance your plans and have the necessary tools at hand. This reduces the amount of time for the job and decreases the chance for dirt to get into the bearing. INSPECTION AND PREPARATION All component parts of the machine should be on hand and thoroughly cleaned before proceeding. Housings should be cleaned, including blowing out the oil holes. Do not use air hose on bearings. If blind holes are used, insert a magnetic rod to remove metal chips that might be lodged there during fabrication. Shaft shoulders and spacer rings contacting the bearing should be square with the shaft axis. The shaft fillet must be small enough to clear the radius of the bearing. On original installations, all component parts should be checked against the detail specification prints for dimensional accuracy. Shaft and housing should be carefully checked for size and form (roundness, etc.). SHAFT AND HOUSING FINISH Shaft surfaces on which the bearing will be mounted must be clean and free from nicks and burrs. For applications with stationary housing and rotating shaft, it is suggested that the bearing seat on the shaft be ground to.6 μm (6 μin.) Ra maximum. If it is impractical to use a ground finish, a machined finish of.2 μm (2 μin.) Ra is acceptable in many cases, but the amount of interference fit should be slightly increased. Housing bores should be finished to.2 μm (2 μin) Ra maximum. MOUNTING CYLINDRICAL ORE EARINGS Heat Expansion Method Most applications require a tight interference fit on the shaft. Mounting is simplified by heating the bearing to expand it sufficiently to slide easily onto the shaft. Two methods of heating are commonly used: - Tank of heated oil. - Induction heating. The first is accomplished by heating the bearing in a tank of oil that has a high flash point. The oil temperature should not be allowed to exceed 2 C (20 F). A temperature of 9 C (200 F) is sufficient for most applications. The bearing should be heated for 20 or 0 minutes, or until it is expanded sufficiently to slide onto the shaft easily. The induction heating method is used for mounting small bearings in production line assembly. Induction heating is rapid. Care must be taken to prevent bearing temperature from exceeding 9 C (200 F). Trial runs with the unit and bearing are usually necessary to obtain proper timing. Thermal crayons melted at predetermined temperatures can be used to check the bearing temperature. While the bearing is hot, it should be positioned squarely against the shoulder. Lockwashers and Locknuts or clamping plates are then installed to hold the bearing against the shoulder of the shaft. As the bearing cools, the Locknut or clamping plate should be tightened. In cases of outer ring rotation, where the outer ring is a tight fit in the housing, the housing member can be expanded by heating. The oil bath is shown in Fig. 26. The bearing should not be in direct contact with the heat source. The usual arrangement is to have a screen several inches from the bottom of the tank. Small support blocks separate the bearing from the screen. It is important to keep the bearing away from any localized high-heat source that may raise its temperature excessively, resulting in race hardness reduction. A Note: Do not remove the bearing from its wrapping until you are ready to mount it. EARING EARING HELD FROM OTTOM Y SCREEN OIL EARING SUPPORT LOCK FLAME URNER Fig. 26. Heat Expansion Method. Flame-type burners are commonly used. An automatic device for temperature control is desirable. If safety regulations prevent the use of an open heated oil bath, a mixture of percent soluble-oil water may be used. This mixture may be heated to a maximum of 9 C (200 F) without being flammable.

SPHERICAL ROLLER EARINGS A MOUNTING PROCEDURES - continued MOUNTING CYLINDRICAL ORE EARINGS - continued Arbor Press Method The alternate method of mounting, generally used only on smaller sizes, is to press the bearing onto the shaft or into the housing. This can be done by using an arbor press and a mounting tube as shown in Fig. 27. The tube can be made from soft steel with an inside diameter slightly larger than the shaft. The O.D. of the tube should not exceed the maximum shoulder height given in the table of dimensions. The tube should be faced square at both ends. It should be thoroughly clean inside and out and long enough to clear the end of the shaft after the bearing is mounted. SHAFT MOUNTING TAPERED ORE SPHERICAL ROLLER EARINGS Use a feeler gage with the thinnest blade of.00 in. Place the bearing in an upright position with the inner and outer ring faces parallel. Place thumbs on the inner ring bore and oscillate the inner ring two or three elements. Position the individual roller assemblies so that a roller is at the top of the inner ring on both sides of the bearing. With the roller in the correct position, insert a thin blade of the feeler gage between the roller and the outer ring. Move it carefully along the top roller between the roller and outer ring raceway. Repeat this procedure using thicker feeler gage blades until one is found that will not go through. The blade thickness that preceded the no-go blade is a measure of RIC before installation. Start the mounting procedure by lubricating the tapered shaft with a light coat of machine oil. Fig. 27. Arbor press method. If the outer ring is being pressed into housing, the O.D. of the mounting tube should be slightly smaller than the housing bore. The I.D. should not be less than the suggested housing backing diameter in the table of dimensions. Coat the shaft with a light machine oil to reduce the force needed for a press fit. Carefully place the bearing on the shaft, making sure it is square with the shaft axis. Apply steady pressure from the arbor ram to drive the bearing firmly against the shoulder. Never attempt a press fit on a shaft by applying pressure to the outer ring or a press fit in a housing by applying pressure to the inner ring. Fig. 28. Slide the bearing onto the shaft as far as it will go by hand. As the Locknut is tightened, the interference fit builds up, resulting in expansion of the inner ring. Periodically measure to keep track of the reduction in RIC. Continue the procedure until the proper amount of reduction is obtained. Do not exceed suggested amount of reduction. As a final check, make sure the remaining RIC equals or exceeds the minimum mounted clearance shown in the table to the right. 04 SPHERICAL ROLLER EARING CATALOG

During mounting, the RIC should be checked at the unloaded roller. If this is at the bottom, make sure that the roller is raised to seat firmly at the inboard position of the inner race. When the suggested amount of RIC reduction has been accomplished, the bearing is properly fitted. Complete the procedure by peening the Lockwasher tang into the Locknut slot or securing the Lockplate. SPHERICAL ROLLER EARING CATALOG 0

Spherical Roller earing Pillow locks INTRODUCTION Timken s capabilities in the engineering and manufacture of heavy-duty pillow blocks provide important user benefits. In addition, Timken s worldwide sales organization is staffed with experienced bearing engineers who are available for consultation on any pillow block or bearing application. Expert engineering DESIGN AND CONSTRUCTION Timken supplies pillow blocks equipped with either tapered bore bearings plus adapters for mounting on straight shafts or cylindrical bore bearings for assembly on shouldered shafts. Timken spherical roller bearing pillow blocks are made of split construction for convenient assembly and disassembly. These units include pry tool slots and the exclusive Pry-Lug fulcrum that simplify bearing inspection, service, and replacement. Caps can be removed easily and quickly without damage to the bearing or housing. Precision fit is ensured by the Timken system of doweling caps and bases together at an early stage of manufacturing, so that they remain a single unit during machining. They are not interchangeable as separate parts and become precisely mated components. assistance is available for applications involving shaft sizes 40 inches and larger such as OF trunnions, bridge blocks and ball mills. If your design calls for shaft sizes or loads not listed in this catalog, contact your Timken representative for information about availability of special units. Timken manufactures pillow blocks in two styles: SAF and SDAF. The larger SDAF block is suggested for extreme duty applications. Caps and bases are made from high-grade, stress-relieved cast iron as standard. They also are available in cast steel. All Timken pillow blocks are designed for four-bolt mounting. Certain smaller sizes are normally furnished for two-bolt mounting. These assemblies are indicated in the tables and can be ordered with optional four-bolt base. Four cap bolts are used in most Timken pillow blocks in order to equalize the pressure between cap and base, preventing loss of lubricant. The illustration below shows all parts of a pillow block assembly that are described throughout this section. olt & Washer LER Seal Ring Spherical Roller earing Fig. 0.

SPHERICAL ROLLER EARINGS MOUNTING ADAPTER VS. STRAIGHT ORE Usually a spherical roller bearing pillow block assembly is mounted on a straight shaft using a tapered bore bearing and adapter assembly. Standard commercial shafting can be used without additional machining. (Suggested shaft diameters are shown on page 20.) Adapter mount also permits maximum flexibility in the axial positioning of the bearing on the shaft and will accommodate light locational thrust loads. Timken pillow blocks for tapered bore and adapter mounted bearings are available in Series 22, 226, 20, 2K and 22K. Adapter mounted spherical roller bearings require the correct removal of diametral clearance from the bearing to prevent relative rotation between inner race and sleeve or shaft. Failure to employ proper mounting procedures can cause heating and reduced bearing performance. For proper shaft mounting of adapter type spherical roller bearings, see page 04 of the spherical roller bearing section. When application conditions produce heavy thrust loads, or a need exists for exact axial location or a positive shaft interference fit, a direct straight bore mounting may be the best option. This requires a shouldered shaft, machined for proper fit, and a straight bore bearing. Timken pillow block assemblies for straight bore applications are available in Series 222, 22, 2 and 22. Suggested fits for shafts in cylindrical bore spherical roller bearings are shown in the engineering section. For applications involving heavy shock, vibration, unbalanced rotating loads or other abnormal conditions, consult your Timken representative. FIXED AND FLOAT PILLOW LOCKS Any style of Timken pillow blocks can be easily installed either at the float or fixed position on the shaft. For the fixed position, a stabilizing ring is added between the bearing outer face ring and the housing shoulder to positively locate the shaft and prevent axial movement. Some applications require centering of the bearing in its housing. To accomplish this, two special width stabilizing rings can be ordered. In the float position, the ring is not used, allowing the bearing to move axially (a maximum of / 8 in.) to compensate for thermal expansion or contraction of the shaft. Pillow blocks ordered by the numbers in the dimension tables are fixed units. To order float units, specify by adding suffix Float or FL to the pillow block number. CLOSED END INSTALLATIONS In some applications, the shaft end is designed to terminate inside the pillow block. For this design, positive fitting end-closure inserts are available to seal out contaminants and retain lubricant. Timken heavy-duty end plugs include O-rings for positive sealing. Designers and installers need to make sure the shaft end does not contact the closure. A minimum of / 8 in. clearance at maximum thermal expansion is suggested between the end of the shaft and the closure. Dimension Y in the tables defines the maximum permissible length of the shaft from the centerline of the pillow block housing. If end closure is desired, specify by adding CL (one end closed) to the pillow block assembly number. LURICATION Timken pillow block housings have been designed for grease and oil bath lubrication. They also can be modified easily to accommodate circulating oil or oil/air mist systems. Grease fittings or sight gages are available upon request. A lubrication groove and oil holes are provided in the bearing outer ring. This feature, designated by adding suffix W to the bearing number, should be specified whenever re-ordering bearings for pillow blocks. In most cases, the fresh lubricant is fed directly to the center of the bearing between the rows of rollers and distributed to the rest of the bearing. This ensures the used lubricant is purged from the bearing. SEALS Precision triple ring labyrinth seals are supplied with all Timken pillow blocks to exclude foreign matter and retain lubricants. The pillow block base includes extra large oil return holes at the bottom of the seal grooves to prevent leakage past the seals. For extremely contaminated or abrasive environments, Timken has developed the exclusive DUSTAC seal. This patented seal offers protection against concentrations of dust or abrasive material that a labyrinth seal cannot keep out. See page 2 for further information on DUSTAC. LOAD RATINGS AND LIFE Load ratings for the spherical roller bearings that are used in pillow blocks are found in the dimension tables on pages 80 through 96. Life calculation formulas are found in the engineering section. In addition to individual bearing selection, the ability of the pillow block to carry the operating load should be considered. It should be noted that the load rating figures supplied in this catalog are applicable only when the load direction is generally toward the base of the pillow block. If the pillow block must be mounted so the load can be applied in any other direction, consult your Timken representative. 2 SPHERICAL ROLLER EARING CATALOG

Spherical Roller earing Pillow locks INCH DUSTAC SHAFT SEAL Suggested for pillow blocks used in extremely contaminated environments, such as taconite mines. Provides protection against residual and airborne contaminants that exceeds the triple labyrinth shaft seal. Contributes significantly to extending bearing life; reduces costs by helping prevent premature bearing damage. ecause of its unique design, no special finish is required on the shaft. DUSTAC is a patented device utilizing a V-shaped nitrile ring that rotates with the shaft and applies pressure to the cartridge face to exclude contaminates.

They also are available to retrofit existing installations. To order any pillow block housings with DUSTAC shaft seal on both sides, add the suffix DV to the number (e.g., SAF222DV). To order pillow block housings with DUSTAC shaft seal and one end closed, add the suffix DC to the number (e.g., SAF2222DC). Standard sizes of DUSTAC shaft seals are shown in the table. Other sizes are available upon request. INSTALLATION PROCEDURE. Check shaft diameters to print specification. Remove any burrs or sharp edges. e sure shaft surface is clean and dry beyond the area of seal location. 2. Expand the V-ring seal over the shaft to the approximate inboard position (reference dimension in the tables). Make sure the lip of the seal faces the bearing.. Slide the seal cartridge onto the shaft until the V-ring fits into its cavity. 4. Mount the bearing, sleeve, Lockwasher and Locknut in normal manner and adjust for internal clearance.. If both ends have seals, repeat steps 2 and with the V-ring going on last with its lip facing the bearing. 6. Thoroughly clean the housing base and remove any paint or burrs from the mating surfaces of the housing cap. 7. Lower shaft, bearing and seals into the housing base, taking care to guide the seals into the seal grooves. 8. On each shaft there must be only one fixed bearing. If the bearing is to be fixed, the stabilizing ring can be inserted between the bearing outer ring and the housing shoulder on the Locknut side of the bearing. All other bearings on this shaft should be centered in the housing. 9. The upper half of the housing or cap should be thoroughly cleaned and checked for burrs. Place it over the bearing and seals. The dowel pins will align the cap to the base. NOTE: housing caps and bases are not interchangeable. 0. After cap bolts are tightened, it is most important to position the V-ring seal to its proper fitted width. This is accomplished by moving the seal until it is flush with the outside face of the cavity. This provides proper compression of the lip against the cartridge face.

SPHERICAL ROLLER EARINGS INCH SINE AR GAGES Tapered-bore, anti-friction bearings are mounted either on adapter sleeves or on tapered shaft seats. In cases where tapered bore bearings are mounted directly on the shaft, the shaft must conform to the tapered bore of the bearing to assure proper fit. If a proper fit is not achieved, the results could be:. Turning of the bearing inner race on the shaft. 2. Uneven loading of the bearing.. Severe inner race hoop stress. 4. Insufficient support (back-up) of the inner race on the shaft. All of these conditions could lead to premature bearing damage. Therefore, the manufacture, maintenance and measurement of accurate shaft tapers is important. There are two accepted ways of measuring tapered shafts: ring gages and sine bar gages. Precision measurement of tapered shafts is difficult with ring gages and may be impossible in the case of large shafts where gages are large, cumbersome and heavy. Sine bar gages provide an accurate and easy method of measurement. Lightweight and easy to handle and learn, sine bar gages achieve precise gaging of the shaft size and taper. Fig. 2.

Spherical Roller earing Pillow locks INCH HYDRAULIC NUTS INTRODUCTION Designed to install and remove tapered bore bearings with minimal effort. Allow better control of the bearing internal clearance reduction without damaging the bearing or other components. Substantially reduces downtime during installation or removal of tapered bore bearings. DESCRIPTION Consist of a female threaded ring and a male ring with two O-ring seals. All hydraulic nuts are supplied with: - Quick connection fittings (male ¼ in..s.p. and female / 8 in. N.P.T.). - Two pipe plugs ¼ in..s.p. - One set of spare O-rings. INSTRUCTIONS When the hydraulic nut is used, the piston must be in the innermost position. For this operation, please ensure the valve of the hydraulic hose is disconnected from the nut so the nut is not under pressure. To contract the piston inside the female threaded ring, insert a rod or bar in one of the four drilled holes located on the outside diameter of the female threaded ring. Screw the hydraulic nut on the thread with the piston in contact with the surface, until the groove machined on the outside diameter of the piston near the outboard face is level with the face of the female threaded ring. One of the two threaded holes must be plugged with the ¼.S.P. pipe plug before the hydraulic nut is pressurized. The maximum pressure permissible in the hydraulic nut is 4000 psi (0 Kpa). The oil viscosity suggested is 400 SUS (00cSt) at operating temperature (SAE 90 oil). To avoid overextension of the piston, a second groove has been machined on the outside diameter of the piston inboard used to judge contraction. When this second groove is level with the face of the female threaded ring, the piston has reached its length of travel as shown in the illustration. If the second groove of the piston travels past the face of the female threaded ring, the hydraulic nut can be damaged. Should the oil start to leak from the piston area, it is certain that the O-ring seals are damaged or worn and need to be replaced. When the hydraulic nut is not in use, ensure that the threaded holes are plugged to prevent entry of contaminants in the piston cavity. To help prevent against corrosion during storage, apply a coat of light oil on the hydraulic nut surfaces. Contact your Timken representative to receive special warnings against reasonably unforeseen dangers. ORDERING COMPONENTS: To order spare components for the hydraulic nuts, order part numbers as listed below: - O-ring Seal Kits: Use the hydraulic nut part number plus the number 2. Example: HMVC 40/2 - Pipe Plug ¼ in..s.p.: Use the hydraulic nut part number plus the number 647. Example: HMVC 40/647 - Quick Connection Fittings (male ¼ in..s.p. and female / 8 in. N.P.T.): Use the hydraulic nut part number plus the number 849. Example: HMVC 40/849 ENGINEERING SERVICES Special applications should be referred to a Timken representative for review. INSTALLATION Hydraulic nut used to mount the bearing on a pull type sleeve. REMOVAL Hydraulic nut used to mount the bearing on tapered journal. Hydraulic nut used to mount the bearing on a push type adapter sleeve. Hydraulic nut used to withdraw a push type adapter sleeve. SPHERICAL ROLLER EARING CATALOG 2

SPHERICAL ROLLER EARING METRIC ACCESSORIES C Accessories for your every need. To complement our line of Timken spherical roller bearings, we offer bearing sleeves and locking devices in a wide range of metric sizes. These accessories are manufactured to the same quality standards as our bearings, ensuring a secure fit to straight and stepped shafts. Available in sizes up to 900mm, bearing sleeves are available in two distinct designs: assembled adapter sleeves and withdrawal sleeves. ADAPTER SLEEVES Timken adapter sleeves are used in conjunction with a nut and locking device to mount a tapered bore bearing onto a straight shaft using a pull-type fit. Smaller size assemblies (7 mm - 200 mm shaft) commonly use simple nuts, whereas larger assemblies (sizes >200 mm) may use HMV hydraulic nuts to assist in mounting. The chart below outlines our part number nomenclature, which is consistent with the world standards for adapter sleeves. Sleeve Locknut Locking Device H standard metric KM M OH hydraulic assist HM M KML ML WITHDRAWAL SLEEVES Withdrawal sleeves feature a push-type mounting arrangement and a locking device (i.e., Locknut or Lockplate) to secure a bearing to a shaft. This design is not as widely used as the adapter sleeve assembly and it does require the use of a specially designed dismounting nut. Timken s part number nomenclature for withdrawal sleeves also conforms to industry-accepted standards.
