Needle Roller and Cage Thrust Assemblies (AXW 20)

SKF needle roller thrust bearings are fitted with a form-stable cage to reliably guide and retain a large number of needle rollers. The diameter deviations of the rollers within one assembly are within 2 micro; M, enabling these bearings to accommodate heavy axial loads and shock loads. These bearings provide a high degree of stiffness within a minimum axial space. In applications where the faces of adjacent machine components can serve as raceways, needle roller thrust bearings will take up no more space than a conventional thrust washer. They can accommodate axial loads acting in one direction only.

SKF supplies needle roller thrust bearings in two designs:

- Needle roller and cage thrust assemblies, AXK series
- Needle roller thrust bearings with a centring spigot, AXW series
For applications where adjacent components cannot serve as raceways, the assemblies can also be combined with washers of various designs.
