Needle roller and cage radial assembliesOverview: Needle roller and cage assemblies are a complement of needle rollers held in place bya cage. The mating shaft and housing are normally used as inner and outer raceways. The unitizeddesign allows for easy handling and installation. Controlled-contour rollers reduce end stresses andpermit operation under moderate misalignment. A variety of cage designs, styles and materials, as wellas multiple roller paths and segmented constructions, meet broad application requirements. Sizes: 6 mm - 150 mm bore. Markets: Automotive and truck transmissions, agricultural and construction equipment,two-cycle engines, pumps and compressors.CCA Features: Special coatings and platings; split and segmented designs for simplified mounting;engineered polymer cages. Benefits: High load capacity and high limiting speed within the smallest envelope.FPOTIMKEN PRODUCTS CATALOGC FPO

Needle Roller and Cage Radial AssembliesADimensional AccuracyNeedle roller groups (gages)Metric series needle roller and cage radial assemblies aresupplied with needle roller complements subdivided into groups(gages) shown in Table 1. The groups are at Timken’s option ifnothing to the contrary is agreed upon at the time of ordering. Thisis in accordance with Grade G2 specified in ISO 3096 standard(see needle rollers, page C326). The group limits of the needlerollers are indicated on the package. Labels of identifying colorsshow the group limits of the needle rollers. The needle roller andcage assemblies of one shipment usually contain needle rollerswith group limits of between 0 to -2, and -5 to -7 mm (colors red,blue and white). Information on needle roller and cage assemblieswith needle rollers of different group limits will be supplied onrequest.Axial Guidance RequirementsNeedle roller and cage radial assembly must be axially guidedby shoulders or other suitable means. The end guiding surfacesshould be hardened to minimize wear and must provide sufficientaxial clearance to prevent end locking of the assembly. Lengthtolerance H11 is suggested.If end guidance is provided by a housing shoulder at oneend and by a shaft shoulder at the other end the shaft must beaxially positioned to prevent end locking of needle roller and cageassembly. The housing and shaft shoulder heights should be 70 to90 percent of the needle roller diameter to provide proper axialguidance.ACCATable 1 – Needle Roller Group Limits (Grade G2)H11H11Group Tolerance MarkingµmIdentifying color of labelor on 6-7M4M6M5M7white lowIn the marking of the gages, P identifies zero (0) or plus ( ), M identifies minus (-).Mounting DimensionsDesign Of RacewaysNeedle roller and cage radial assemblies use the housing boreas the outer raceway and the shaft as the inner raceway. In orderto realize full bearing load rating and life the housing bore and theshaft raceways must have the correct geometric and metallurgicalcharacteristics. The housing should be of sufficient cross sectionto maintain adequate roundness and running clearance underload. Additional design details for housings and shafts used asouter and inner raceway can be found in the engineering sectionof this catalog. The only limit to precision of the radial clearanceof a mounted assembly is the capability of the user to hold closetolerances on the inner and outer raceways. The suggested shafttolerances listed in Table 2 are based on housing bore tolerance G6and apply to metric series radial needle roller and cage assemblieswith needle rollers of group limits between P0M2 and M5M7.BBccGuidance in the H11BBccGuidance on the shaftGuidanceononthetheshaftshaftGuidanceMounting In SetsNeedle roller and cage radial assemblies that are mounted sideby side must have needle rollers of the same group limits to ensureuniform load distribution.ALubricationOil is the preferred lubricant for most applications. In criticalapplications involving high speeds, ample oil flow must be provided.Where assemblies are subjected to high centrifugal forces, suchas in epicyclic gearing, or inertia forces as in the small end of aconnecting rod, the contact pressure between the cage and therev0.13Nov9Page4747rev0.13Nov9Pageraceway guiding surface becomescritical. The allowable contact88pressure depends on a combination of the induced force and therubbing velocity between the cage and raceway and the rate oflubricant flow. Consult your Timken representative when cageswill be subjected to high induced forces.AASpecial DesignsNeedle roller and cage radial assemblies made to specialdimensions or configurations, such as those which are split toassemble around a one piece crankshaft, can be made availableon special order. Special coated or plated cages to enhance lifeunder conditions of marginal lubrication and high induced forcescan also be made available.ATable 2 – Suggested Shaft Tolerances For Housing BoresMachined To G6Nominal shaft diameter in mm 80 80Asmaller than normalj5h5normalh5g5larger than normalg6f6TIMKEN PRODUCTS CATALOGC Radial clearance Shaft tolerance
