Basic Life Rating for Ball Bearings Calculator

Basic bearing life (L₁₀):

Basic dyanmic load rating (C):

Equivilant dynamic load (F):

How This Is Calculated

$$ L_{10} = \left(\frac{C}{F}\right)^3 \cdot 10^6 $$ where:

L₁₀ = Basic bearing life (revolutions)

C = Basic dyanmic load rating (N)

F = Equivilant dynamic load (N)

Assumptions

There are no energy losses.
The loading is constant over the bearings lifespan.
The load distribution is uniform.
The effects of lubrication are ignored.
