R eim rod ends and spherical plain bearings are intended for linkage applications where a bearing must accommodate significant misalignment. hile spherical plain bearings offer flexibility in housing and mounting design, the user bears the responsibility for housing design and the cost of housing manufacture. Rod ends offer greater mounting convenience and provide a compact, lightweight, economical design alternative to the spherical plain bearing. eim earings Company offers the industry s widest selection of rod end types and sizes. Rod nd Construction eim offers three basic rod end constructions. The four piece rod end uses race inserts, typically of brass, to provide lubricity in the bearing area. This design offers reduced internal clearance, and provides smoother operation. It is ideal for dynamic applications. The two piece rod end uses a rod end body which is formed around a spherical ball. The comparatively heavy cross section of the rod end body in the two piece design provides high strength. This makes the two piece rod end ideal for highly loaded, static applications where high strength is required. The cartridge type rod end consists of a spherical plain bearing mounted in a rod end body. This design allows the optimum selection of materials for ball, race and rod end body. The cartridge type rod end can also accommodate a PT liner for selflubrication. This design is best suited for aircraft and military applications where material selection is a primary design consideration. Self-lubricating Rods nds eim produces metal-to-metal rod ends and self-lubricating rod ends. All metal-tometal rod ends, including brass insert four piece types, require regular lubrication. This can be accomplished by splash or immersion oil lubrication, or by greasing through optional lubricators (grease fittings). Self-lubricating types are used where relubrication is not practical, or in applications where relubrication is not desirable, such as on food processing machinery or in clean environments. eim self-lubricating rods ends are available with bonded PT fabric liners, or with molded, engineered thermoplastic race inserts. Rod nd Grades eim rod ends are offered in four grades: precision, commercial, aircraft, and military. Precision rod ends are manufactured to tight tolerances for applications requiring improved linkage accuracy and reduced looseness. Commercial rod ends are produced using standard materials and manufacturing methods, and are an economical choice for industrial applications. Aircraft rod ends use premium materials, and have magnafluxed rod end bodies. riginally intended for aircraft applications, aircraft rod ends are used in many industrial applications where a high degree of reliability is required. Military rod ends are produced in strict accordance with all applicable military specifications and are typically used in military and commercial aviation applications, or when Mil-Spec approval is required. Precision Rod nds Grade M and four piece precision rod ends use brass race Series Size Range M, 3/" to 1" Product eatures Precision Grade rass Inserts our Piece Construction inserts for lubricity and clearance control.

R CM C IM Self Lubricating Series nvironmental Characteristics or commercial applications where a self-lubricating bearing is either desirable or necessary, eim developed eim Series bearings. eim bearings are designed with an engineered thermoplastic race material and offer a lower coefficient of friction than metal-to-metal types that use conventional lubricants. It is a resilient material that performs well under vibratory and dynamic loading and withstands dynamic loads up to 3500 PSI. here to Use IM earings eim bearings should be used in applications where the bearing cannot be periodically lubricated or where it is desirable to eliminate the need for regular maintenance. They are also recommended for applications where there is considerable vibration. The resilience of the engineered thermoplastic race absorbs vibration without causing fretting or galling of the surface. The torque level of the bearing will be low because of the low coefficient of friction of the hardened steel ball on the engineered thermoplastic race. The coefficient of friction for eim bearings is approximately 0.1, but will vary somewhat depending on the loads, speeds, temperatures, and solvents that are present. The chart on this page shows a typical bearing wear pattern of eim bearings and how they vary with number of oscillations. ear in Inches.0.00.00.004.002 0 eim bearings have good environmental tolerances. They offer advantages over bearings that use a nylon race because the eim engineered thermoplastic race absorbs very little moisture. It is generally resistant to alcohols, aldehydes, esters, ethers, hydrocarbons, weak acids and bases, water and agricultural chemicals. imensional stability is quite good when exposed to these substances, however the eim engineering department should be contacted for recommendations on specific performance characteristics. ear vs. scillations 4 PM 2 PM,000 0,000 500,000 scillations (+/- radial rotation) This chart shows typical wear of engineered thermoplastic race bearings (load at one-half static rating - ball surface velocity as noted),

STATIC RAIAL LA Technical ata R The maximum static radial load permissible for a rod end depends on three factors: race material compressive strength; rod end head strength; and shank strength. The maximum static radial load is determined by taking the lowest of the three following values: Race material compressive strengths (R) R = x x X Material MATRIAL STRSS TAL Allowable Stress (PSI) rass 30,000 Aluminum ronze 35,000 300 Series Stainless Steel 35,000 Low Carbon Steel 52,000 Alloy Steel 140,000 Rod end head strength (T) insert construction T = [ - ( +.17 )] x x X cartridge type construction T 2 1 = [ ( 2 2-2 ) + ( x SIN 2-1 - ) - (.. of bearing x )] x X angle of expressed in radians MISALIGNMNT The angle of misalignment in a rod end is controlled by the outside diameter of the head. The maximum degree of misalignment is obtained when the head contacts the side of the fork or clevis in which it is mounted. Maximum misalignment is calculated by the following formula. Shank Strength (S) here: male threaded rod end S = [(root diameter of thread 2 x.7) - (N 2 x.7)] x X female threaded rod end S 1 = [(J 2 x.7) - (major diameter of thread 2 x.7)] x X = all iameter = ousing idth X = Allowable Stress (see table) = ead iameter N = iameter of rilled ole in Shank of Male Rod nds J = Shank iameter of emale Rod nd STATIC AXIAL LA Rod nd Angle (α): here: α α = SIN -1 SIN -1 = ead diameter or diameter of outer race = ousing width = all width The maximum available axial load for a rod end is determined by the following formula. This formula does not take into consideration bending of the shank due to a moment of force. Also, this formula does not consider the strength of the stake in cartridge type of construction. Axial Strength (A) here: A =.7 [( +.17 ) 2 2 ] x X X = Allowable Stress (See Table) = all iameter = ousing idth 2

General Information Sleeve earings Sleeve earings eim manufactures sleeve bearings in a wide range of materials and sizes for industrial, agricultural, and aerospace applications. Pages 52 and 53 describe two standard series of self-lubricating bearings that utilize UNILN Type liner material. This liner meets the requirements of SA-AS120 (formerly MIL--120). In addition to these standard plain and flanged series, eim designs and manufactures specials to meet specific customer requirements. orking either from a drawing, application description or sample part, eim also applies UNILN liners to customer supplied bearings. Lined Sleeve earings (ushings) - Characteristics UNILN liners in sleeve bearings eliminate the need for lubricating the bearings during their useful life. The UNILN liner is a cost effective solution to many design problems where lubrication is impractical or undesirable. UNILN lined sleeve bearings are ideal for applications where periodic shock loads or vibrations are encountered. eim s new Type liner is recommended for sleeve bearing applications where temperatures range from -5 to 350. UNILN liners are highly resistant to most chemical solvents encountered in bearing applications. UNILN lined sleeve bearings have a lower coefficient of friction than metal-to-metal lubricated bearings. or additional information on UNILN liner characteristics see page 54. You are encouraged to consult eim s engineering department for recommendations on specific application problems. Shaft ata An important factor influencing the life of UNILN lined sleeve bearings is the condition of the mating shaft. It is recommended that the shaft have a surface finish of RMS or better and a minimum surface hardness of Rc 40. Commonly preferred shaft materials are hardened corrosion resistant steels, hard anodized aluminum and any metal accepting hard chrome or nickel plate. The mating component should be designed such that there are not sharp edges which could damage the liner during assembly of the sleeve bearing. Cross binding or edge loading on the bearing should be avoided. esign Inquiry To request an engineering design on a specific application, submit either a drawing or sketch or submit the pertinent information. All requests will receive prompt design engineering attention and follow-up. R 51

Technical ata Self-Lubricating earings R UNILN - Self-Lubricating abric Liners To meet the increasing technical demands on self-lubricating bearings, eim has developed UNILN Type, a new and improved liner material. eim s Type is qualified to procurement specification SA-AS120 (formerly MIL--120). UNILN Type is unique in the family of teflon type bearing material. Type is a low coefficient of friction composite of three materials. Most composite bearing materials consist of one layer of low coefficient of friction material usually teflon fiber, layered or interwoven with either a highly abrasive fabric such as fiberglass, or a low-load bearing fabric such as dacron, coated with resin. Type combines a low coefficient of friction, high tensile, high compressive strength fabric with chemically bonded teflon fiber to form the Type matrix. hy UNILN TYP? UNILN Type liner is recommended over other bearing materials for the following reasons. 1. igh teflon fiber content. Teflon has the lowest coefficient of friction of known materials today. 2. The bonding material is a polyallomer consisting of two polymers. ne polymer provides adhesive properties. The second polymer provides the correct degree of elasticity. 3. The backing or basic high strengthfabric in Type has an inherent coefficient of friction only slightly higher than teflon (.019). here are UNILN Type earings used? Type bearings are designed for use in low surface speed high unit loading where metal to metal is limited or non-desirable. Type bearings are available with ratings in high static unit loads up to 0,000 psi. or specific radial and dynamic load ratings on Type bearings, consult the eim engineering department. UNILN Type can be used with many combinations of hardened steel, aluminum, titanium and plated surfaces, in many environments, and in temperatures -0 to 350. Type VV Liner or less demanding or higher temperature applications, eim recommends its Type VV liner. The higher temperature Type VV carbon filled liner is particularly suited for high frequency and low load applications in temperatures from -5 to 500.

Smooth peration The burnished races of the eim ball bearings provide far smoother operation than other unground ball bearings. This feature may allow a eim design to be used in place of precision ground bearings in many applications. asy Mounting ptional flanged..s are available to simplify housing design and mounting. eim UNIAL ball bearings are also available with extended inner rings to allow clevis mounting. Sealing Shields and seals are available as options to retain lubricant and exclude contamination. o you require a special design for either the inner or outer race?
