Overview:

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 a thrust load between two relatively rotating objects while greatly reducing friction.

Needle roller and cage thrust assemblies can also be unitized with lipped washers which service as raceway surfaces for the needle rollers.

Washers can be supplied separately or can be mechanically unitized to the needle roller thrust assemblies for ease of handling.

Markets: Automotive automatic and manual transmissions, automotive accessories (compressors, steering gears, etc.) agricultural and construction equipment.

Sizes: 6 mm - 140 mm (0.2362 in. - 5.5118 in.).

Features: One-way fool-proof assembly features, anti-rotation locking features and lubrication flow enhancements.

Benefits: High-speed performance and application flexibility.

Needle roller and cage thrust assemblies are available in a variety of sizes. They all have very small cross-sections. This catalog includes the most popular, standardized and non-standard designs. If back up surface cannot be used as a raceway, hardened washers are available.
