Equivalent dynamic bearing load PF for calculating comparative rating life

Bearing arrangement		Load case		Comparative equivalent
				dynamic radial load
		1a)	Fa ≤ 0,6 FrL/KL	PFL1 = 0,5 FrL + 0,83 KLFa
				PFL2 = 0,5 FrL - 0,83 KLFa
				PFN = FrN
Locating	Non-locating
		1b)	Fa > 0,6 FrL/KL	PFL1 = 0,4 FrL + KLFa
				PFL2 = 0
				PFN = FrN
		1c)	Fa = 0	PFL1 = FrL
Locating	Non-locating			PFN = FrN

Values of the thrust factor K_L are listed as K in the product tables.

For load cases 1a) and 1b), the load rating for one roller row needs to be applied when using P_FL.
The load rating for one roller row can be obtained from 

C_F(row) = 0,58 C_F(bearing)
