Precision Ball Lead Screw

Because the ball screw makes use of ball motion, the beginning torque is extremely small, and there will be no crawling phenomenon like sliding motion, which can ensure the recognition of accurate micro feed. Ball screw has the traits of high lead precision and specific sensitivity. When synchronous transmission is required, a variety of devices of ball screw pairs with the same lead can be used to acquire exact synchronization performance. The hardness of the ball and raceway can reach HRC58~63. The shape of the raceway is accurate, the rolling friction and wear are very small, and it has accurate accuracy retention, reliability and provider life.

Description

Ball screws and lead screws are mechanical linear actuators that are normally used to translate rotary motion into linear motion and are generally used in CNC machines.

All screws serve the same motive of converting rotary motion into linear motion, they have awesome variations in their design, performance, and suitability for specific sorts of applications.

Ball screws employ recirculating ball bearings to reduce friction and amplify efficiency, whereas lead screws make use of helical threads and a nut to produce linear movement.

Lead screws are steel bars with threads as that of a ordinary screw, and the relative motion between the screw and nut reasons the linear motion of the latter.
