Basic Life Rating for Roller Bearings Calculator

Life expectancy (L₁₀):

Dyanmic load rating (C):

Equivilant load (P):

How This Is Calculated

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

L₁₀ = Life expectancy (revolutions)

C = Dyanmic load rating (N)

P = Equivilant 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.
