Ball screw repair with a 36 month warranty! Delivered in 12 to 24 hours!
Mitchell Industrial offers a three year warranty because we do a complete rebuild of your ball screw, not just a reload. Ever notice how a brand new ball screw will last years and some rebuilds only last a few months? That's because a new ball screw is precision ground to the nut (same diameter grooves) and the steel balls are precision lapped to fit. When we do a ball screw repair, we are restoring it to new condition. The screw and nut are ground within .0002 of each other and grade 25 steel balls are precision lapped to fit. The end result is a ball screw repair that's as good as new with a 36 month in use warranty. Other ball screw rebuild companies claim the same level of quality, yet the warranty is less then half.
 

We can guarantee zero backlash & a T.I.R. of +/- .0002 per linear foot!
And we can guarantee it will perform like new for 36 months! Typical ball screw repair:

1: Check the load of the nut at each end of the screw & in the center locating any trouble spots
2: Complete disassembly & cleaning for inspection and record all sizes & depths of ball grooves
3: Grinding (ball grooves) of your screw to a T.I.R. of .0002 per linear foot is reached
4: ID grind nut (ball grooves) to the same size & tolerance as the screw
5: Replace / repair return tubes, wipers internal returns as needed
6: Grind & lap a new set of balls to match the newly ground ball grooves on your screw/nut
7: Assemble all parts with lapping compound and run at high speed for 30 to 45 minutes, if there are any tight spots or problem areas, both screw & nut will be reground & lapped to size
8: Disassemble screw & nut for cleaning / inspection and make adjustments as needed
9: Final assembly to original preload, replacing all wipers & seals, inspection, testing & crating
* If bearing journals or ends are worn, we can grind, chrome plate & grind back to original size.

The end result is a completely remanufactured ball screw that will last years instead of months. We offer a 36 month warranty because we completely remanufacture your ball screw, not just reload. No other company can match our warranty or our level of service.

Nothing is as important as downtime!
When your machine is down you're loosing thousands of dollars per day. That's why Mitchell Industrial is on call 24 hours a day, 7 days a week. We specialize in ball screw repair and have over 30 years experience. With our onsite emergency repair service, you can be back in production in a matter of a few hours.
Not all ball screws can be repaired onsite. Please contact your nearest service center for full details.

Upfront pricing, free estimates
Ask around, some of our competitors charge for estimates after you've sent them in a screw. They'll charge you for the inspection, the disassembly and a handling fee. Mitchell Industrial will never charge you for an estimate. Send us your parts for a free evaluation. If you are not satisfied with our pricing, we will gladly ship the parts back to you (or another repair facility) free of any charges and we'll even pay for all shipping. We'll only charge you if you agree with our pricing and give us authorization to perform the necessary repairs.

 On site ball screw repair!  Minimal downtime! No shipping!
Crashed? Run the nut off of the screw? Strange noises at high speed? There is no reason to be down a few days, we can fix it in a few hours. We'll send our experienced technicians to your facility to perform the repairs right there in your shop and have you back in production in just a few short hours.
Not all ball screws can be repaired on site. Contact your nearest service center for full details & pricing information. Onsite ball screw repair does NOT qualify for our 36 month warranty. Our service technicians are available & on call 24 hours, 7 days a week and are ready to fly out to your location to get you back into production immediately!

Believe it or not, this is the same screw!
It's hard to believe and there is only one way we can prove it to you. Send us your scrap screw. Send us something that you were going to throw away and allow us to prove our abilities. Some of our competitors are using similar photos, but if you take a closer look, it's just a ball screw covered in heavy grease & oil. This is an actual rebuild for an aerospace facility where the screw was left outside for 4 months. Call our Cincinnati plant for full details and references on this repair project.
