Profile: Superior Ball Screw Repair specialize in rebuilding ball screws. We rebuild all brands and sizes. Each ball screw assembly we recondition goes through our step by step rebuilding process. Of course, all ball screws are not alike. Each screw receives special attention where it is needed most. Some ball screws require certain parts replaced rather than reconditioned. Often we must custom make parts for ball screws when replacement parts are not available. The ball screw is put through a series of tests and then final inspection to ensure quality, precision, and durability. We offer a ?re-ball only? service for customers who have run the ball nut off the end of the screw but do not need to have their ball screw assembly completely rebuilt. This service is typically only available on new ball screws.
