Product Overview

Our ground positioning ball screws are primarily used for demanding applications such as machine tools or measuring and testing machines. The precision ground ball contact surfaces deliver high positioning and repeat accuracy. This means the path distance can be measured via the spindle. Furthermore, these ball screws operate smoothly and hold constant torque.
