#### Ball Bearings: Guide to Selection, Applications Calculations

X and Y are factors required for the calculation of equivalent dynamic bearing load for single and double row deep groove ball bearing, dependent upon axial load (Fa) and radial load (Fr). Therefore, if P o < F r, P = P o = F r. P o = Axial load and is equal to P o = + Where, F r is the radial force and F a is the Axial Force.
