Description

Lead screws convert rotatory motion (turning ) into linear motion.

It offers good axial stiffness and excellent, smooth small displacements.

Lead screws are generally preloaded with an axial load that helps to maintain a permanent contact between the nut and screw filets.

Applications

Lead screw are commonly used in  low power applications like

Linear actuator

positioner mechanisms

Machine slides

Machine tools

Vises

Presses

Jacks

Electric linear actuators
