Ball bearings are rated by a manufacturer for a life of 106 revolutions. The catalogue rating of a particular bearing is 16 kN. If the design load is 2 kN, the life of the bearing will be P x 10⁶ revolutions, where P is equal to _________

L₁₀ =		C		³
		W

where L₁₀ = Basic life rating in millions of revolutions C = Basic dynamic load rating
P = Equivalent dynamic radial load

∴ L₁₀ =		16		³	=	5
