Loads


Minimum load

For additional
information
(→ Requisite minimum load)
Frm = 0,01 C

The importance of imposing a minimum load increases where accelerations in the bearing are rapid, and where speeds are in the region of 75% or more of the limiting speed quoted in the product tables. The weight of the components supported by the Y-bearing, together with external forces, generally exceed the requisite minimum load.

Axial load carrying capacityFa ≤ 0,25 C0

The maximal permissible axial load of any locking mechanism is always > 0,25 C0.
Equivalent dynamic bearing load

information
(→ Equivalent dynamic bearing load)
Fa/Fr ≤ e → P = Fr

Fa/Fr > e → P = X Fr + Y Fa
