ACME
Lead Screw Efficiency Estimator
The Following Applet will help you estimate the efficiency of a lead screw given the diameter and the lead. Keep in mind this is an approximation only.
Diameter (in):
Enter any value (0 to 2.5 inches)
Lead (in):
Enter any value (0 to .5 inches)
Efficiency with Plastic Nut:
%
Efficiency with Bronze Nut:
%
The results take into consideration friction, nut material type, and lead. It assumes that the lead screw is of good quality and is cetralizing ACME thread form.
