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 table.

Axial load carrying capacity

Fa ≤ 0,25 C0

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

Equivalent dynamic bearing load

For additional information → Equivalent dynamic bearing load, P

Fa/Fr ≤ e → P = Fr

Fa/Fr > e → P = X Fr + Y Fa

Equivalent static bearing load

For additional information → Equivalent static load

P0 = 0,6 Fr + 0,5 Fa
