Loads


Minimum load

For additional
information
(→ Requisite minimum load)


Perform calculations

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 dynamic bearing load

For additional
information
(→ Equivalent dynamic bearing load)
Fa/Fr ≤ e → P = Fr + Y1 Fa

Fa/Fr > e → P = X Fr + Y2 Fa

Perform calculations
Equivalent static bearing load

For additional
information
(→ Equivalent static bearing load)
P0 = Fr + Y0 Fa
