We specialize in NTN ball screw repair. NTN makes a precision quality ball screw but they are hard to replace. They’re not always on the shelf when you need them and it could take a while before one is located for you. The most typical problem we see with NTN ball screws is the plastic ball return has flared out and isn’t working the way it should. Unfortunately the manufacturer doesn’t sell just the returns or spare nuts, you need to purchase a brand new ball screw and nut assembly.


We can repair your NTN ball screw by manufacturing new ball returns out of bronze or T6 aluminum. These returns will last 5 times longer than the original plastic.


What will it cost to repair my NTN ball screw? We can save you 50% or more from ordering a brand new ball screw. Typically it depends on the amount of work needed. Call us with the size of your NTN ball screw and let us know what exactly is wrong with it. We’ll give you a price over the phone and we’ll be able to deliver on your schedule.


How fast can my NTN ball screw be repaired? Normal delivery time on all ball screw repair is 3 to 5 days. If you need it faster, we offer 24/48 hour emergency delivery. We have most NTN ball screws, nuts, and ball returns in stock. We may be able to swap out your ball screw to get you up and running the same day!
