How to Size and Select Ball Screws: An Engineer's Guide

Ball recirculation inside the ball nut can affect precision and repeatability. As a result, ball nuts are available with a range of pre-load options to reduce or remove the axial play as they rotate around the screw. This allows for better repeatability, for example, because no motion is lost from the clearance in the balls as they reengage.
