If individual single direction bearings, bearing sets, or double direction bearings have to accommodate both axial and radial loads, the equivalent dynamic bearing load for each direction of axial load can be determined as follows:

Fa/Fr ≤ 2,35 → P = X Fr + Y Fa

Fa/Fr > 2,35 → P = 0,97 Fr + Fa

For bearings that accommodate axial loads only:

P = Fa

where

 P = equivalent dynamic load [kN] Fr = radial load [kN] Fa = axial load [kN] X = radial load factor – for single direction bearings: table 1 – for double direction bearings: 1,9 Y = axial load factor – for single direction bearings: table 1 – for double direction bearings: 0,55

Preload is considered to be an axial load. For bearing sets in any arrangement, the equivalent dynamic bearing load must be calculated separately for each load direction.

If individual single direction bearings, bearing sets, or double direction bearings have to accommodate both axial and radial loads, the equivalent static bearing load for each direction of axial load can be determined as follows:

P0 = Fa + 4,35 Fr
