Ball screw is made of screw, nut and ball. it's function is to turn the rotary motion into liner motion, which is a further extension and development of ball screw. the significance of this development is to move into a rolling bearing from slidingaction. with little friction, ball screws are widely used in various industrial equipment and precision instruments.

Applications:

1. Engraving machines;

2. High speed CNC machinery;

3.Semi-Conductor equipment;

4. Auto-machinery.

Rolled ball screws can not only be used in general machinery, but also in many advanced industries. Rolled ball screw with a motor assembles electrical-mechanical actuator, which is more eco-friendly than hydraulic pump sy  stem. Nowadays it's applied to electric vehicles, solar power plants, railway decices, and many emedical and leisureequipments.
