Acme screw thread - friction
Acme screw thread - friction
(OP)
Does anybody have any friction data for acme screw threads? I have a 1/4-16 double lead screw thread and want to compute the torque required to move the screw.

In addition, if you enter a coefficient of friction, it will calculate a drive efficiency, and a back drive efficiency. This can be used to calculate the torque you are interested in.

In general, a greased rolled steel thread with a steel nut (tapped thread) would have a coefficient of friction of approx. .13. Using a brass nut with a tapped thread would be about .11.
