Ball screw preload: What you need to know - Linear Motion Tips

The most noticeable increase in rigidity of a ball screw assembly occurs when a non-preloaded ball nut is replaced with a preloaded version. The ball nut rigidity (R N) is one component of the total rigidity of the screw assembly, along with the screw shaft, end bearings, and housing. Preload also increases motor drive torque and decreases life
