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.


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


  • High speed performance and application flexibilty.
