Needle roller and cage assemblies

Bearing arrangements with axial needle roller and cage assemblies have a high axial load carrying capacity, are extremely rigid and can support axial forces in one direction.

Bearing arrangements with axial needle roller and cage assemblies are particularly suitable where:

  • high axial forces occur in one direction and no radial loads are present
  • the load carrying capacity of comparable axial deep groove ball bearings is no longer adequate and the very high axial load carrying capacity of axial cylindrical roller bearings is not yet necessary.
  • the axial space available is only extremely small.
  • the bearing parts can or must be mounted separately.

 

Description

Axial needle roller and cage assemblies with axial bearing washers

Axial needle roller and cage assemblies AXK comprise geometrically stable plastic or metal cages fitted with a large number of needle rollers.

For particularly low axial section heights, axial needle roller and cage assemblies can be integrated directly in the adjacent construction. The running surfaces for the rolling elements must therefore be produced as rolling bearing raceways.

The axial needle roller and cage assemblies are generally combined with axial bearing washers. This is appropriate if, for example, high speeds occur and the bearing washers must therefore be precisely centred or the running surfaces for the rolling elements cannot be configured as a rolling bearing raceway.
