How does a ball screw work
WebA Ball Screw Actuator uses a high precision nut with recirculating ball bearings that rotate around a ground screw thread. In principle this is very similar to a standard ball race with the load being transmitted by the rolling balls. 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.
