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.
