What are the characteristics of the ball screw?

1. The driving torque is 1/3 compared with the sliding screw pair Since there are many balls between the screw shaft of the ball screw pair and the screw nut for rolling motion, high movement efficiency can be obtained. Compared with the past sliding screw pair, the driving torque is less than 1/3, that is, the power required to achieve the same motion result is 1/3 of the use of the rolling screw pair. It is very helpful in saving electricity.

2, high precision guarantee The ball screw pair is produced continuously in the world's highest level of mechanical equipment made in Japan. Especially in the factory environment for grinding, assembling and inspecting various processes, temperature and humidity are strictly controlled due to perfect quality management. The system ensures the accuracy is fully guaranteed.

3, micro feed may be Since the ball screw pair uses the ball movement, the starting torque is extremely small, and there is no creep phenomenon such as sliding motion, and accurate micro feed can be ensured.

4, no backlash, high rigidity The ball screw pair can be pressed, and the axial gap can be negative due to the pre-pressure, thereby obtaining higher rigidity (the ball is pressurized by the ball in the screw, when it is actually used for mechanical devices, etc., due to the ball The repulsive force can increase the rigidity of the silk mother.)

5, high-speed feed may The ball screw achieves high-speed feed (motion) because of its high efficiency and low heat generation.
