     1. Compared with the sliding screw pair, the driving torque is 1/3
  Because there are many balls in the rolling motion between the screw shaft of the ball screw pair and the screw nut, higher motion efficiency can be obtained. Compared with the past sliding screw pair screw, 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. Very helpful in terms of power saving.
  2, the guarantee of high precision
The ball screw pair is generally produced continuously with the world's highest level of machinery and equipment. Especially in the factory environment of the grinding, assembly, and inspection processes, the temperature and humidity are strictly controlled, due to the perfect quality management system So that the accuracy can be fully guaranteed.
  3, micro-feed is possible
   Because the ball screw pair uses ball motion, the starting torque is extremely small, and there will be no crawling phenomenon like sliding motion, which can ensure the realization of precise micro-feed.
  4, no backlash, high rigidity
The ball screw pair can be preloaded, because the preload can make the axial gap reach a negative value, and then obtain higher rigidity (the ball screw is used to prepress the balls. When actually used in mechanical devices, due to the ball The repulsive force can increase the rigidity of the nut).
  5, high-speed feed is possible
   The ball screw can realize high-speed feed (movement) due to its high motion efficiency and low heat generation.
