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.
When your CNC machine tool begins to lose its accuracy, the ball screws and the thrust bearings on the journals are usually the cause. Send your worn or damaged ball screw to us for a complete evaluation. To determine the cost of reconditioning a ball screw, for a no-charge inspection.
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.
If these four critical conditions are met, the ball screw can be reloaded and given up to a 6-month warranty.
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.
