Ball Screw Mechanism

Ball Screw Mechanism

A ball screw mechanism is a precision linear motion assembly designed to convert rotary motion into smooth, accurate linear movement. Commonly used in packaging machinery, automation systems, CNC equipment, and servo-driven motion applications, the ball screw provides high efficiency, low friction, and excellent repeatability compared to standard lead screw designs.

By using recirculating ball bearings between the screw shaft and nut, the mechanism reduces mechanical resistance and allows controlled movement under load. This makes it ideal for applications requiring accurate positioning, consistent travel speed, and long service life in industrial environments.
