Introduction to Ball Nut
A ball nut is a crucial component in a ball screw system. It is designed to convert rotary motion into linear motion with high efficiency and precision. The ball nut contains a series of balls that roll between the nut and the screw shaft, reducing friction and enabling smooth and accurate movement. Ball nuts are widely used in various industries, including machine tools, automation equipment, robotics, and aerospace, due to their high load – carrying capacity, long service life, and excellent positioning accuracy.
