Ball screws are used as drive / movement threads as well as positioning and measuring threads. The ball screw is not a sliding screw drive. Rolling bodies (balls) are used.

In the case of the ball screw, the nut and spindle each have a semicircular cross-section, which together form a tube filled with balls. The rolling elements move towards the end of the nut during the rotary movement and are then returned there via a deflection inside the nut.

Ball screw drives are mainly used when very high positioning and repeat accuracy are required.

Compared to trapezoidal screw drives, ball screws allow significantly higher speeds and loads at the same time (pxv value). The efficiency is significantly higher than with sliding screw drives.

We supply ball screw nuts in various diameters and pitches. The following standard nuts are available: single flange nut, flange double nut, single cylinder nut, cylinder double nut and screw-in nut.
