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.

Double nut ball screw with improved operating characteristics
As illustrated in Fig. 2, increasing the value of preloading above a certain level has little impact on the overall effective stiffness.The axial stiffness of a typical ball screw assembly is primarily defined by the geometry of the ball screw shaft [10].Hence, for most applications, the rigidity of the ball screw nut is of secondary importance when choosing …
