Ball Screw Lead Vs Pitch

A single start lead screw has a lead equal to its pitch, a double start lead screw has a lead twice its pitch, a 4 start lead screw has a lead 4 times its pitch, etc. pitch is simply the distance between threads in mm. the number of starts on a lead screw can be found by looking at the end and counting the starts.

    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.
