WebJan 13, 2024 · Ball screws work in a similar way to traditional screws, but the significant advantage of using a Ball Screw is that it uses ball bearings running in spiral channels to transfer loads. In high precision applications, it is often necessary to convert the rotary motion of the motor into the Linear Motion of the payload. One way to do this is to use … WebBesides 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.
