Precision Repair & Reconditioning Services

Partial ball replacement can provide short-term relief but does not restore original geometry, preload stability, or long-term accuracy under load. Our complete remanufacturing process regrinds screw and nut raceways, matches precision balls, and reassembles to OEM preload with full inspection and test documentation—delivering multi‑year reliability in production environments.

Our 7-Step Ball Screw Rebuild Process

1. Check the load of the nut at each end of the screw & in the center, locating any trouble spots.
2. Complete disassembly of the ball screw and nut, checking ball size, ball groove depth, returns etc.
3. Thread grinding (ball grooves) your screw end to end.
4. ID grind the nut (ball grooves) to the same size & tolerance as the screw & replace all tubes and returns.
5. Precision grind & polish a new set of balls to match the newly ground ball grooves on your screw/nut.
6. Final assembly to original preload, replacing all wipers & seals, followed by inspection, testing & packaging.
7. If bearing seatings are damaged, we can OD grind and chrome plate to OEM specs.
