Ball Screw: The Complete Guide
The ball screw comprises a screw, nut, steel ball, preloading piece, reverser, and dust protector. Its function is to convert rotational motion into linear motion, which is a further extension and development of the Acme screw. The important significance of this development is to change the bearing from sliding action to rolling …

Ball Screws for CNC: Easy Guide [Bearing Blocks, and Anti
Besides ground versus rolled, ball screws come in different accuracy grades that you should be aware of: C0 – 3um or 0.0001″ per 300 mm / 12″. C3 – 7um or 0.00027″ per 300 mm / 12″. C5 – 14um or 0.0005″ per 300 mm / 12″. This refers to how close the position will be after the screw has turned through 12″ of motion.

Pre-Tensioning the Shaft
Give us a call! The purpose to pre-tension a ball screw is to compensate for thermal expansion during operation and thus avoid compressive forces as the shaft expands between the two fixed bearings. The goal is to stretch the screw sufficiently to maintain at least some tension at the highest anticipated temperature.
