Minimum load

For additional
(→ Requisite minimum load)
Frm = 0,02 C

Perform calculation

The weight of the components supported by the bearing, together with external forces, generally exceed the requisite minimum load. If this is not the case, the bearing must be subjected to an additional radial load.

Equivalent static bearing load

For additional

P0 = Fr

SKF recommends applying a static safety factor
s0 ≥ 3, i.e. s0 = C0/P0 ≥ 3.
