Examples of Selecting a Ball Screw
Screw shaft diameter: 30 mm; lead: 60 mm (large lead Ball Screw) Ball centertocenter diameter D= mm D 70000 70000 N 2 = = = 2240 min 1 Thus, with a Ball Screw having a screw shaft diameter of 20 mm and a lead of 20 mm, the maximum rotational speed exceeds the dangerous speed.
