Top 10 ball nut Manufacturers in China

Introduction to Ball Nut

A ball nut is a crucial component in a ball screw system. It works in conjunction with a ball screw to convert rotational motion into linear motion or vice - versa. The ball nut contains balls that roll between the nut and the screw, reducing friction and enabling high - precision and efficient movement. Ball nuts are widely used in various industries such as machine tools, robotics, aerospace, and automotive, where accurate linear positioning and smooth motion are required.
