Ball Screw with Nut details Ball screw is made of screw, nut and ball. The 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 sliding action; With little friction, ball screws are widely used in various industrial equipment and precision instruments.

The following table list the differences in appearance and characteristics for your reference. Rolled Ball Screw Application: 1. Engraving machines; 2. High speed CNC machinery; 4. Auto-machinery. 3. Semi-Conductor equipment; 5. Machine tools; 6. Industrial Machinery; 7. Printing machine; 8. Paper-processing machine; 9. Textiles machine; 10. Electronic machinery; 11. Transport machinery; 12. Robot etc. Rolled ball screws can not only be used in above 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 system. Nowadays it's applied to electric vehicles, solar power plants, railway devices and many medical and leisure equipments. Kindly pls contact me if you have any question!!!!!!!!!!!!!!!!!!!!!!
