Is the Preload of the Ball Screw related to Accuracy of Ball Screw?

The preload affects the accuracy of the ball screw travel and has nothing to do with the load.

The preload is related to the accuracy of the ball screw itself, If it's rolled ball screws, it's not necessary to adjust it to preload P2, Beacuse the accuracy of the rolled ball screws itself can't be achieved.

The load of the whole set ball screw is determined according to the form of the nut, and the data of dynamic and static loads are not determined by other factors, and only the ground ball screw of C5 and C3 can be adjusted to P2 and P3. The higher the preload level, the tighter the gap between the nut and the ball screw itself, then the accuracy will do the best.
