Lead Screw Acme 12mm Ball Screw is made of screw and ball nut. It's function is to turn the rotary motion into linear motion which is a future extension and development of ball screw. The significance of the development is to move into a rolling bearing from sliding action. With little frication, Ball Screw are widely used into various industrial equipment and precision instruments. Applications: Ball Screw are widely used in aircraft and missiles to move control surfaces, especially for electric fly by wire, and in automobile power steering to translate rotary motion from an electric motor to axial motion of the steering rack. They are also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing. Factory: Equipment: Shipping: Contact Me:
