It's widely used in all kinds of industrial equipments,precision NC machine tool
Ball screw assembly is consisted of ball screw nut and rod. The function is transfer the rotary motion into linear motion or transfer the linear motion into rotary motion.Ball screw is widely used for all kinds of industrial equipments and precision instrument.Since 1964, the company developed the China's first ball screw, it has on the leading position in China in the research and manufacture of ball screw
The ball screw pair is to place an appropriate amount of rolling elements between the screw and the screw groove of the nut as an intermediate transmission body, and with the help of the ball return device, it constitutes a screw drive mechanism in which the ball circulates infinitely in a closed loop. As shown in the following figure. When the screw or nut turns, the ball is pushed to form a repeated cyclic movement of the ball chain in a closed circuit
Feature
1. Space saving nternal circulate design
2. Low friction force with 1/3 over acme screw
3. Ensure for high accuracies
4. Micro feed with tolerance within in 0.1μm
5. Zero backlash, high stiffness.
