leadscrews

Rotary-to-linear converters

Leadscrews are threaded rods that convert rotational motion into linear motion.

A nut travels along the screw's threads as it turns, moving objects with precision.

They're essential in machine tools, 3D printers, and CNC equipment where controlled linear movement matters: The printer's leadscrews needed lubrication.

Distinguished from ball screws by their simpler sliding contact.
