6-8 Hour Emergency Reload & Minor Repair

In rare cases a wear condition can be corrected properly by reloading the nut and screw with over-sized balls and shipped same day upon recipt. The reloading procedure is carried out only if the following conditions are met:

The ball screw and nut thread raceways are in good condition. The ball screw and nut raceway radii and root diameters are in tolerance for the ball that is to be used in reloading. This insures that the ball comformity and contact angle are correct. The ball screw thread root diameter must be straight or require minimal lapping. The ball screw thread lead must be within machine tool tolerance. Customer approval is required if lead is out of tolerance. Only if these four critical conditions are met will the ball bearing leadscrew be reloaded.

Should an emergency condition exist, and IBR does not have an exchange unit in stock, they will make the unit functional, if possible.

At the same time, a drawing can be made and quoted for the manufacture of a new unit on an emergency basis.
