INCH THRUST BEARING NTA SERIES
Overview: 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 flexibility.
