Needle roller and cage thrust assemblies are complements of small diameter needle rollers arranged in a spoke-like configuration. Needle rollers are equally spaced by means of a cage whose web section separates the rollers and provides guidance to keep them tracking in an orbital path. The purpose of these assemblies is to transmit thrust loads between two relatively rotating objects while greatly reducing friction.

Needle roller and cage thrust assemblies also can be unitized with lipped washers which serve as raceway surfaces for the needle rollers. Washers can be supplied separately or can be mechanically unitized to the needle roller thrust assemblies for easy handling.

Size range: 6 mm to 140mm (0.2362 in. to 5.5118 in.)

Design Attributes
Dimensions for bore and O.D. of thrust assemblies and washers are nominal.
Thrust washers burnished at least one quarter of bore area (remainder is rough breakaway finish).
O.D. finish of washers will be as blanked.
Thinner washers may be out of flat due to distortion in hardening in the free state (expected to flatten out under load).

Applications
Automotive automatic and manual transmissions
Automotive accessories (compressors, steering gears, etc.)
Agricultural equipment
Construction equipment

If drawn cup needle bearings would provide the following series: HK, BK, F, FY, FH, MF, MFH, MFY, SCE, BCE, SCH, BCH, SN, B, BH, M, MH, etc.

If drawn cup needle bearings is formed with thin steel plate through precision punching with very sectional height and big load capacity. This kind of bearings are especially applicable to the big quantity production with economic demands.

Stable combination is used between the needle bearings and the bearing cage. No axle fixture is required. Even under high speed and heavy load condition, the bearing functions can be fully maintained. Furthermore, no lubricating for a long time is possible due to its high storage volume of grease

Needle roller bearing are used in applications where compact size is required and radial space is limited. This is because these needle roller bearing only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. They have a smaller cross-section, higher load-carrying capacity and greater rigidity, which in turn gives size and weight reductions in machinery. Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance so they are much more compact. The typical structure consists of an inner race, a needle cage which orients and contains the needle rollers, the needle rollers themselves, and outer race. Radial needle bearings are cylindrical and use rollers parallel to the axis of the shaft. Thrust needle bearings are flat and use a radial pattern of needles.

Headsets in bicycles use a crooked pattern, so they are able to absorb both parallel and thrust power impacts. Needle bearings are heavily used in engine components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of a rear-wheel drive vehicle typically has at least 8 needle bearings (4 in each u joint) and often more if it is particularly long, or operates on steep slopes. We have a vast range of needle bearings available in different sizes and tolerances for various applications. Our needle roller bearings and cage assemblies are available in single row, double row, solid cage, split cage and metric as well as inch sizes. . Single and double row bearings are available with or without ribs, and with or without inner rings. Thrust bearings are available in single row roller and cage assemblies.
