High efficiency:

As the ball screw pair realizes ball rolling friction between the ball screw and the screw, the ball screw can get up to 97% transmission efficiency compared with all kinds of sliding spiral (such as trapezoid), so that the driving torque can be reduced to less than 1/3.

Pretightening and high rigidity

With pretightening requirements, the ball screw pair can achieve the pre tightening between the nut and the screw through a variety of ways, such as the change guide and the double nut prepressing, so as to eliminate the axial gap or realize the negative clearance and the axial rigidity of the ball screw pair can be greatly improved. The Gothic groove allows the ball to have the best contact with the nut and the screw shaft.

High life span

Ball screw nut, the screw hardness of the screw reach HRC58~62, the ball hardness of HRC62~66, and they are rolling friction between them, so the ball screw pair can achieve high fatigue life and precision life under the appropriate design.

high reliability

In view of the weakest link in the actual use of the ball screw, the metal return device made by MM technology is used to improve the reliability of the ball screw pair.

Micro and high speed feed can be realized

The ball screw does not produce the peristaltic phenomenon in the sliding spiral, so the correct trace feed can be realized; as long as the feed pulse is small enough, the ball screw pair can realize submicron feed. In addition to the low temperature of the ball screw and the large guide screw, the high speed feed can be realized, and the large guide ball screw pair can realize 100m/min even higher feed speed on the premise of guaranteeing the critical speed below the ball screw.
