Thrust Needle Roller - Inner Ring / Shaft Washer (WS)
- Shaft washer.
- Heavy thrust washer, these metric series thrust washers are made of bearing quality steel, hardened and precision-ground on that flat raceway surfaces.
- Their bores and outer diamter are not ground, but provided satisfactory surfaces for shaft-piloting or housing-piloting arrangements.
About Thrust Bearings, Assemblies, Washers
- 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.
About Mounting Tolerances Thrust Needle Roller And Cage Assembly
- Thrust needle roller and cage assemblies are complements of small diameter needle rollers, arranged in a spoke-like configuration.
- Needle rollers are equally spaced by means of a cage, its 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.
- Thrust needle roller and cage assemblies also can be unitized with lipped washers to serve as raceway surfaces for the needle rollers.
- Washers can be supplied separately or can be mechanically unitized to the thrust needle roller and cage assemblies for ease of handling.
Features
- One-way fool-proof assembly features, anti-rotation locking features and lubrication flow enhancements.
Benefits
- High speed performance and application flexibilty.
