Ball Screw Repair Estimate
Need a price for ball screw repair service? Call or email us with the following information:
Approximate overall length & diameter of your ball screw. Is your ball screw a single or double nut? what problems are you having with your ball screw? Backlash? Loss of tolerance?
Be specific. When do you want your ball screw back in production?Call us with the information and we’ll get you an immediate price & delivery time right over the phone.
Even if your ball screw is obsolete, we can manufacture and reverse engineer any parts needed to get your ball screw working like new.
Loss of Accuracy
Passed the backlash compensation? Loss of accuracy? The screw looks good, but you’re getting errors or noise. Your nut is worn and the balls are worn out. Precision grinding the ball grooves to accept a larger diameter ball will solve backlash, loss of accuracy, noise, etc. We’ll have your ball screw working like brand new in just a few days. All ball screw repairs are backed by our 24 month warranty covering parts and labor.
Noisy Ball Screw
Noisy in one direction? All the balls fell out? Your returns are worn down allowing the balls to move (instead of roll) and aren’t being “picked up” in the return tube/slot. Eventually your ball screw will fail and all of the balls will fall out or it will seize. Call us with a detailed description of the problems you are experiencing . We can estimate your ball screw repair right over the phone and arrange for same day pickup and crating if needed.
Small Segment Worn Out
Poor accuracy in one area, the rest of the screw is fine? Over time your ball screw will wear in the area you use it most and not return to the proper position. Minor adjustments on the machinists side can get you through a few production runs, but eventually your ball screw will seize or trip the alarm. We can precision grind the ball grooves to .0002 TIR to eliminate all uneven wear and get your ball screw performing like a brand new unit in 5 days or less
Out of Backlash Compensation
Is your ball screw slightly out of the backlash compensation? The reason this happens is the balls have worn out inside the nut. Example: The original size was 0.250, now the balls are worn to 0.2485. Most of the time a polish and reload will solve the problem, if not we can precision grind and make adjustments to get your ball screw back to OEM tolerances. This type of repair can usually be done in 24 to 48 hours standard delivery.
What is the ball screw lead? It is linear distance traveled for each turn. If your ball screw lead is one inch, turning the nut one full rotation will result in exactly one inch of travel. If the lead is half an inch, turning the nut one full rotation will result in half an inch of travel. You can measure your ball screw lead by the distance traveled for one complete turn. This information isn’t necessary for a repair estimate, but is required for the manufacturing of a new screw & nut.
