An automotive transmission Ball Screw is a mechanical transmission element used to transmit power. It consists of balls, screws, nuts and supports. When the screw rotates, the nut is pushed along the screw rod, thus achieving power transmission. Ball Screws have the function of converting motion to linear motion, so they are widely used in automotive transmissions. It is able to improve the gearshift speed and accuracy of the gearbox, making the gearbox more stable and reliable. In addition, automotive transmission ball screws are also able to withstand large loads and torques, with excellent durability and longevity.
