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.
Enter any value (0 to 2.5 inches)
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.
