What are the characteristics of ball screw?

1.Small friction loss and high transmission efficiency

Because there are many balls rolling between the screw shaft and the screw nut of the Ball Screw pair, high movement efficiency can be obtained.Compared with the sliding screw pair in the past, the driving torque is less than 1/3, that is, the power required to achieve the same movement result is 1/3 of the sliding screw pair.It helps save electricity.

2.High precision

Ball screw is generally produced with the world's highest level of mechanical equipment, especially in the grinding, assembly, inspection of the factory environment of each process, the temperature and humidity are strictly controlled, because of the perfect quality management system to ensure the accuracy.

3.High speed feed and micro feed

Ball screw pair because of the use of ball movement, so the starting torque is very small, there will be no crawling phenomenon like sliding movement, can ensure the realization of accurate micro feed.

4.High axial stiffness

Ball screw pair can be added with prepressure, because the pre-pressure can make the axial between negative, and then get higher rigidity (ball screw by adding pressure to the ball, in practice for mechanical devices, due to the repulsive force of the ball can make the screw part of the rigidity).

5.Can't self-lock, has the transmission reversibility
