How can I reduce or eliminate the backlash in a ball screwThe other method is to use a ball nut with adjustable preload. These use two ball nuts with a spring assembly between them. The spring assembly presses one nut 

Ball-screw basics: Debunking the myths | Machine DesignTypically, most backlash is between the ball nut and screw, and a range of nut designs helps remove backlash by preloading the system. Preloaded ball nuts have What is preload? - Linear Motion TipsFeb 23, 2015 — Preload is the elimination of internal clearance between the rail and carriage (or between the ball screw and ball nut). This makes the system
