Loads

Dynamic loads

As track rollers are not supported in a housing, the outer rings deform, leading to an altered load distribution and bending stresses in the outer ring. 

The basic load ratings listed in the product table take into account the altered load distribution, while the maximum radial loads Fr max (→ product table) are based on the bending stresses.

Static loads

Permissible static load is the lower value of F0r max and C0 (→ product table).

Axial loads

Cam rollers are intended for predominantly radial loads. However, axial loads can occur due to skew or tilting or when the outer ring runs against flanges for brief periods.

Axial loads acting continuously on the outer ring may reduce the cam roller service life. To evaluate these influences, contact the SKF application engineering service.
