About Thrust Needle Roller And Cage Assemblies, Thrust Washer

  • 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

  • On NTA inch type thrust needle roller and cage assemblies, the cage bore has a larger contact area and a closer tolerance than outer diameter.
  • Therefore, bore piloting is preferred for these assemblies.
  • To reduce wear, it is suggested that the piloting surface for the cage be hardened to an equivalent of at least 55 HRC.
  • Where design requirements prevent bore piloting, the NTA thrust needle roller and cage assemblies may be piloted on the outer diameters.
  • It should be noted that the "diameter to clear washer O.D." given in the bearing tables is not suitable for outer diameter piloting.
  • For such cases, suitable O.D. piloting dimensions should be determined in consultation with your representative the engineering section of this catalog.
