Dynamic axial load carrying capacity

Cylindrical roller bearings are primarily designed to accommodate radial loads. Several designs are also suitable to accept thrust forces acting in one or both directions to a limited extend.

Thrust forces applied to cylindrical roller bearings generate sliding friction between the roller end faces and the guiding flanges.

Hence, an optimum lubrication is crucial. Furthermore, every thrust load creates a tilting moment on the rollers. 

This requires an additional radial loading to ensure an effective function of the bearing.

The thrust forces applied to the bearing must not exceed the following limits:

 
Fa ≤ 0,4·Fr
 
y
 
 Fa ≤ 0,1·Cr
 
However, axially loaded cylindrical roller bearings also require:
  • adequate lubrication
  • no shock loads
  • sufficient heat dissipation
  • an adequate support of the bearing flanges by the adjacent parts
