Backlash is strictly the axial free motion of the ball screw to the ball nut, it is not rotational.. HOW TO MEASURE FOR BACKLASH. 1. Place a magnetic base indicator directly on the screw. Put a .0001 indicator point on the nut flange. …
A ball nut with all the backlash removed is called preloaded. There are several ways to reduce or eliminate the backlash in a ball screw assembly: At the factory level we can select ball sizes to minimize the backlash. This works well for small lead to diameter ratios, like a 5x25mm. In some cases we can preload a ball nut in this way.
Backlash- If positive backlash it could be ballscrew end float, worn drive nut,or guide way play. If negative backlash the machine parameter might be overcompensated. If unequal backlash then there could be a wind up in the ballscrew where it becomes stiff on one end of the travel.

Ball screw preload reduces axial play and increases rigidity. In many applications, the primary reason for using a preloaded ball screw is to reduce internal clearance between the raceways of the nut and screw, which causes axial play (backlash). Reducing or eliminating backlash in turns improves the repeatability of the screw assembly, since ...
