A ball screw bearing is composed of a screw, a nut, a reverse device, and a ball for converting rotary motion into linear motion or converting linear motion into rotary motion. The ball screw bearing is a type of rolling-element bearing that uses balls to reduce friction and transfer motion between two parts. The bearing comprises a threaded shaft and a nut with matching ball grooves. The balls roll between the grooves, allowing the nut to move linearly along the shaft. In this blog, ATO will discuss what a ball screw bearing is and its features.
