1. Low friction loss and high transmission efficiency

Because there are many balls in the rolling motion between the screw shaft and the screw nut of the ball screw pair, higher motion 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 sliding screw pair. Very helpful in terms of power-saving.

2. High precision

Ball screws are generally produced continuously with the world's highest level of machinery and equipment. Especially in the factory environment of grinding, assembly, and inspection, the temperature and humidity are strictly controlled. Due to the perfect quality management systemaccuracy is fully guaranteed.

3. High-speed feed and micro feed are possible

Because the ball screw pair uses the ball motion, the starting torque is extremely small, and there will be no crawling phenomenon like sliding motion, which can ensure the realization of accurate micro feed.

4. High axial rigidity

The ball screw pair can be pre-loaded because the pre-load can make the axial gap reach a negative value, and then obtain higher rigidity (in the ball screw, pressure is applied to the balls. When used in mechanical devices, due to The repulsive force of the balls can increase the rigidity of the nut).

5. It cannot be self-locked and has the reversibility of transmission
