1 OMBINE BEARINGS
2 Tecnical features Types of combine bearings Naella combine neele bearings type RAX an erivatives are esigne to support simultaneously bot a raial an an axial loa. Tey comprise a neele trust bearing (or roller trust bearing) an neele cage retaine in a coon outer ring. Te tecnical caracteristics of te trust bearing an te neele cage are set out in te appropriate sections. Tese bearings form one integral unit permitting easy storage, anling an fitting. Teir ig raial an axial loa capacities an small space requirement enable cost effective solutions to be acieve. alculations for combine bearings are carrie out taking te axial component an te raial component separately witout transforming te axial loa into an equivalent raial loa. Te operation of te trust bearing an te neele cage inepenent of one anoter preclues any interaction armful to precise axial an raial rotation. Axial expansion of te saft, for example, will ave no effect on te accuracy of te raial component. Te bearings can be use witout inner rings or trust plates, if te saft journals serving as raceways are of sufficient arness an possess a suitable surface finis. Harness of HR will ensure tat te full capacity of tese bearings is attaine. Lower arness figures will entail a reuction in te static an ynamic capacities (bot axial an raial) as sown in te tables of imensions (see Tecnical Section).

3 Tecnical features Types of combine bearings ombine bearings type RAX 700 an RAXF 700 ombine bearings type RAX 700 possess a onepiece outer ring forme from tin seet steel accurately controlle an arene by suitable eat treatment. Te sape of tis outer ring prevents weakness in te area between te axial component an te raial component, even after te latter as been tigtly fitte into a ousing. Tis type of combine bearing is inexpensive an occupies little space, tus proviing a very economical solution. Because tey are easy to use an can be fitte rapily, tey are often employe in preference to an arrangement wit two separate neele bearings. lose-en combine bearings type RAXF 700 ensure perfect sealing at te en of a saft an o not require te use of blin ousings or en caps. Stanar combine bearings type RAX 400 an RAX 500 ombine neele bearings type RAX 400 an RAX 500 comprise a trust plate an an outer ring macine separately an joine by a strong metal insert. Tis arrangement prevents localise stresses an weakness in te area between te two components, tus eliminating te risk of amage uring mounting or operation. Altoug combine bearings type RAX 700 soul be consiere first on grouns of economy, combine bearings wit tick outer ring type RAX 400 or RAX 500 soul be use wen operating conitions require iger limit loas or greater rotational accuracy.

RAIAL PLAY ombine bearings types RAX 700, RAXF 700 Te fit of a combine bearing wit tin outer ring in te ousing etermines, to a large extent, te imension uner te neeles an consequently te raial play uring operation. Te recoene saft an ousing tolerances give a raial play wose limits are suitable tor most normal applications. To obtain a closer clearance, it is possible to matc te saft iameters wit te iameters uner te neeles of te bearings, after te latter ave been fitte into teir ousings. Te possible ifferences in te stiffness of ousings an te variations of clamping force resulting from te tolerance buil up o not permit to establis a range of imensions uner te neeles for every application. However, for ousings of very tick steel, taking into account te probable restraining force, te variations of te imensions uner te neeles after installation will be witin te tolerances given below: + 15/ + 50 μm up to F w / + 60 μm up to F w = 25 a F w = / + 65 μm up to F w = 45 Outer iameter : Normal tolerance class accoring to 158

6 Tecnical features Types of combine bearings SUPPORTING FAES- RAEWAYS Te bearing souler must be a flat face at rigt angles to te ousing axis, oterwise axial precision will be affecte an te smoot running caracteristics of te trust bearing will be iminise. Similarly, te saft souler, on wic te neeles of te trust bearing rotate or on wic te trust plate is supporte, must be flat an square to te axis. Te eviation from true parallelism between te two supporting faces must be no more tan: a combine bearing wit trust plate. a combine bearing witout trust plate. In te case of an assembly were neiter trust plate nor inner ring is use, te saft journal on wic te neele rotate must ave sufficient arness, i.e HR to ensure maximum loa capacities are attaine. lf te saft souler is use irectly as a raceway for te neeles of te trust bearing or, if it supports a tin trust plate (tickness 0.8 or 1.5 ), it must be rigi an continuous trougout te area of circulation of te neeles boune by imensions E b an E a. A tick trust plate can be supporte on a smaller saft souler or on one tat is iscontinuous (as in te case of splines), provie te eflection of te plate oes not affect te smoot running or require accuracy of te trust bearing. TYPIAL ARRANGEMENTS USING OMBINE BEARINGS RAX an RAXF 700: see page 162. RAX 400 (or 500) an RAXPZ 400 (or RAXZ 500): see page 163. RAXN 400 (or 500) an RAXNPZ 400 (or RAXNZ 500): te typical applications for tese macine-tool quality combine bearings use witout inner ring an wit or witout tick trust plate are ientical to tose for te corresponing stanar combine bearings (see page 163). Te special inner rings ( or 20600) esigne for macine-tool quality combine bearings are of sufficient wit to permit centring of te trust plate an tus eliminate te nee for a saft souler. min=ea L-2 Fw (8) INSTALLATION Te bearing must be correctly aligne wit te ousing. lt is wise to use a small press fitte wit a manrel aving a supporting face square to te axis an covering te wole area boune by imensions E b an E a. Tis meto prevents te trust component from unergoing sock loa wic migt amage te bearing. Wen RAX or RAXF 700 bearings are place in position uring installation care must be taken to ensure tat te force exerte by te press oes not excee te axial limit loa sown in te table of imensions. Te fitting of inner rings on safts manufacture to te recoene tolerances is usually sufficient to rener te use of retaining rings unnecessary. However, if it is necessary to employ a ring to support an ajacent pinion, tis ring must ave an outer iameter sligtly smaller tan imension Fw to enable it to pass smootly into te bearing wen te saft is introuce. 160
7 Tecnical features Types of combine bearings LUBRIATION Wen te applie axial loas are relatively ig an te application allows te use of oil as te esire meto of lubrication, bearing types RAX 500 soul be given consieration. ombine bearings wit a ust cap may use oil lubrication, altoug teir esign makes tem better suite for use wit grease lubrication. ombine bearings are typically sippe protecte wit a corrosion preventive compoun tat is not a lubricant. Te bearings may be use in oil or grease lubricate applications, witout removal of te corrosionpreventive compoun. However, it may be avisable to remove te corrosion-preventive compoun before packing te bearings (wit a suitable grease) to obtain optimum grease performance an to minimize te possibility of confusing grease bearings wit bearings containing corrosion preventive. LOA RATINGS alculations for combine bearings are carrie out taking te axial component an te raial component separately witout transforming te axial loa into an equivalent raial loa.
