Ca = Dynamic load rating (lbf)
Fcml= Cubic mean applied load (lbf)
ℓ = Roller screw lead (inches)
The expected L10 life of a roller screw is express as the linear travel distance that 90% of the screws are expected to meet or exceeded before experiencing metal fatigue. The mathematical formula that defines this value is below. The life is in millions of inches (MM). This standard L10 life calculation is what is expected of 90% of roller screws manufactured and is not a guarantee. Travel life estimate is based on properly maintained screw that is free of contaminations and properly lubricated. Higher than 90% requires de-rating according to the following factors:
95% x 0.62
97% x 0.44
99% x 0.21
96% x 0.53
98%x 0.33
