Product Description

 

Product Description

Product Description:
A lead screw (or power screw) is a mechanical component that converts rotational motion into linear motion. It consists of a threaded shaft (screw) and a mating nut, where the nut moves along the screw's threads when torque is applied. Lead screws are widely used in precision machinery, actuators, and positioning systems due to their simplicity and efficiency.
