SR Series Life Curves

The L10 expected life of a roller screw linear actuator is expressed as the linear travel distance that 90% of properly maintained roller screws manufactured are expected to meet or exceed. This is not a guarantee and these charts should be used for estimation purposes only. The underlying formula that defines this value is:

Travel life in millions of inches, where:

C = Dynamic load rating (lbs)
F = Cubic mean applied load (lbs)
S = Roller screws lead (inches)

L10 = (C/F)3 x S =

All curves represent properly lubricated and maintained actuators.
