Beware of rebuild companies that tell you your ball screw just can't be repaired. They're just trying to sell you a new (more expensive) screw.
Why should I repair my ball screw when I can just order a new one?
Three simple reasons. Price, downtime and warranty.
Pricing: Ordering a new replacement ball screw from the O.E.M. or authorized dealer can cost thousands of dollars. Rebuilding your existing screw will save over 60% from replacement in less then 1/2 the time.
Downtime: Ordering a new screw can take 5 to 7 days. Our average rebuild time is just 24 to 48 hours. Emergency delivery time is under 24 hours. Some exchanges are in stock, ready for immediate delivery.
Warranty: All of our rebuilds are backed by an 18 to 24 month warranty. If for any reason our ball screw rebuild fails, it's rebuilt or replaced free of charge! New and used screws from authorized dealers come with a 60 to 90 day warranty at best, most of the time there is no warranty. Other rebuild companies only offer a six month warranty. We guarantee all of our work for 18 to 24 months from the install date!
All rebuild companies are NOT the same.
Lots of companies offer "re-balling" of a screw, which is fine if you want it to last a few months. If you want it to last a few years (with an 18 to 24 month guarantee) then you need to do a complete rebuild.
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, tubes, etc.
3: Thread grinding (ball grooves) your screw end to end until a TIR of .0002 per linear foot is reached
4: ID grind the nut (ball grooves) to the same size & tolerance as the screw & replace all tubes
5: Precision grind & polish a new set of balls to match the newly ground ball grooves on your screw/nut
6: Assemble all parts with lapping compound and run the screw at high speed for 30 to 45 minutes
7: Disassemble screw & nut for cleaning / inspection and make adjustments as needed
8: Final assembly to original preload, replacing all wipers & seals, inspection, testing & crating
If bearing surfaces or journals are damaged, we can OD grind and chrome plate back to OEM specs
The end result is a completely remanufactured ball screw that will last years instead of months. We offer a 24 month warranty because we remanufacture your ball screw and guarantee it will last. Some companies offer you different "levels" of repair service for different prices with different warranty lengths. We only do complete rebuilds, with a 18 to 24 month warranty. No other company can match our warranty or our level of service.
