Preloading in Ballscrew & LM Guideways – SuperslideAug 8, 2020 — Preloading is used to increase the accuracy and rigidity of a ball screw system. It makes the system more rigid by creating a load between the ball 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 more rigid by creating a load on the linear guide (or ball screw), which reduces deflection when an external force is applied
