Load carrying capacity

Dynamic loads

As indexing roller units 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).
