 · The critical speed of a ball screw is the first order natural frequency of the screw shaft. As a screw shaft rotates, it begins to whip – much like a jump rope. This behavior limits the screw's critical speed. A screw shaft will naturally experience some bending, or sagging, due to its own weight. As the screw rotates, it tends to vibrate ...
