Calculation of Equivalent LoadsEquivalent Load

The equivalent load of radial bearings may be calculated using the following equation:

where

P :	Equivalent load (N)
F r :	Radial load (N)
F a :	Axial load (N)
X :	Radial load factor
Y :	Axial load factor

The values of X and Y are listed in the bearing tables. The equivalent radial load for radial roller bearings with = 0° is

In general, thrust ball bearings cannot take radial loads, but spherical thrust roller bearings can take some radial loads. In this case, the equivalent load may be calculated using the following equation:
