The #1 cause of failure for ball screws is chips, dirt & debris lodged in the nut. This causes premature wear of your internal ball bearings and the ID of your nut. This wear will show itself with out of backlash compensation issues, loss of tolerance, noise at high speeds, etc. A worn set of ball bearings and a worn nut will cause severe errors in your work.

Our solution is incredibly effective and inexpensive. We’ve developed our own wiper system that works 70% better than most OEM’s plastic ring they use as a wiper. We install thick industrial felt that is vacuum impregnated with epoxy resin and is vacuum formed around the threads of your ball screw shaft & inside your ball nut. This allows for a tighter seal and allows 70% less chips, dirt and debris to enter into your nut. All of our ball screw repairs come with our new wiper system. A clean and well lubricated nut will last for years, maintenance free.

Why do ball screws fail and need repair? The #1 cause of failure is a worn nut with worn internal ball bearings. The ball nut always wears more than the screw, the screw is used in one section at a time, where the nut is constantly recirculating and traveling on the ball bearings. A worn nut with worn balls will cause all kinds of issues from backlash, poor finish, noise, etc. The #2 cause of failure is chips, dirt or debris in the nut. Over time debris will get into the nut and cause damage to the nut and ball bearings causing premature failure, loss of tolerance and could eventually seize the nut on the screw.

Got worn out bearing journals on your ball screw? CNC Maintenance does precision OD grinding and hard chrome plating in house to get your bearing surfaces back within tolerance in 24/48 hours.
