What are the characteristics of ball screw bearing?

A ball screw bearing is a bearing composed of a screw, a nut, a reverse device and a ball, which is used to convert rotary motion into linear motion or convert linear motion into rotary motion.What are the characteristics of ball screw bearing?

1. Small friction damage.
Due to the high efficiency of the balls, there are many balls rotating between the ball shaft and the screw nut, so higher motion efficiency can be obtained. Pushing the torque below 1/3 the driving force required for the same motion conclusion is 1/3 the sliding rod. This is helpful in saving energy.

2. High precision
Ball screw bearing is generally produced by the world's highest level machines, especially in research, cutting, assembly and so on. Check the manufacturer's environmental levels, ambient temperature, and other steps. Due to the perfect quality management mechanism, the accuracy is fully guaranteed and the environmental humidity is strictly controlled.

3. High-speed feed and micro-feed
It is most likely a ball screw bearing, because it uses ball motion, so the running torque is small, it is not easy to slide, and the accuracy of the micro-inlet can be guaranteed.

4. High radial bending stiffness
The ball screw bearing can increase and pre-stress the tension, because the pre-working pressure can make the radial spacing negative, so as to obtain higher rigidity (according to the working pressure of the ball screw, in the specific use of mechanical equipment, due to the exclusion force of the ball can increase the stiffness of the wire).
