Axial roller bearings are assembled with an axial roller cage,
with a GS housing piloted washer and with a WS shaft piloted
Usually axial roller bearings are required when axial needle
bearings are not able to stand heavier axial loads.
Dimensional tolerances are of PO precision class, but under
request axial roller bearings and thrust washers for axial
bearings of WS, GS and ZS series, can be supplied with P5 and
P6 precision tolerance.
