1. Low friction loss and high transmission efficiency
Due to the ball screw pair screw shaft and screw nut between a lot of ball in the rolling motion, so you can get higher movement efficiency.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 sliding screw pair.It’s very helpful in saving electricity.
2. High accuracy
Ball screw pair is generally the world’s highest level of continuous production of mechanical equipment, especially in the grinding, assembly, inspection of the process of the factory environment, temperature, humidity has been strictly controlled, due to the perfect quality management system to ensure the accuracy of the full.
3. High speed feeding and micro feeding are possible
Ball screw pair is due to the use of ball movement, so the starting torque is very small, there will be no sliding movement as crawling phenomenon, can ensure the realization of accurate micro feed.
4. High axial stiffness
Ball screw pair can be added with pre-pressure, because the pre-pressure can make the axial clearance to negative value, and then get a higher rigidity (ball screw by adding pressure to the ball, in the actual use of mechanical devices, etc., due to the ball’s repulsion force can make the mother part of the rigid enhancement).
5, not self-locking, with the reversibility of transmission
