We are your leading repair center for ball screw service industry since 1980 MER specializes in reconditioning all types of ball screw assemblies with internal or external ball return systems.

Minor Ball Screw Repair Service

In certain cases, a minor wear condition can be corrected properly by reloading the nut and screw with over-sized balls. This reloading procedure is carried out only if the following conditions are met.

  • The ball screw and nut thread raceways are in good condition
  • The ball screw and nut raceway radii and root diameters are in tolerance for the ball that is to be used in reloading. This ensures that the ball conformity and contact angle are correct.
  • The ball screw thread root diameter must be straight or require minimal lapping.
  • The ball screw thread lead must be within machine tool tolerance. Customer approval is required if lead is out of tolerance.

If these four critical conditions are met, the ball screw can be reloaded and given up to a 6-month warranty.

Ball Screw Reload

Sometimes on integral preloaded nuts (even in good condition), an oversized ball used to offset wear and to establish preload will not run at the proper contact angle. This results in a short wear life and the reload procedure is not carried out. If the screw thread radius and root diameter are not out of tolerance, then they could be polished (or lapped) and proper reconditioning would require a new ball nut only, which is given a 12-month warranty.
