Our ground positioning ball screws are mainly used in highly demanding applications such as machine tool 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.
