P = Applied Load (effective). XF r + YF a (3 for ball bearings and 10/3 for roller bearings) ( X = 1 and Y = 0 always). 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.
