ABSTRACT:
The specification discloses a ball screw having an internal return which is selectively removable externally of the ball nut for servicing. The return is held in place by a spring clip operatively fitted into a dove-tail slot built into the exterior of the ball nut. The provision of the dove-tail slot provides for easy removal and replacement of the internal return, external insertion of the ball bearings when the ball screw must be reassembled for any reason, and, if desired, for shimming the internal return to keep the return at the proper height when the ball screw is rebuilt.
