ABSTRACT:
This is a method for supporting a pump shaft, or the like, within a tubing wherein bearing supports are provided which can be inserted and removed from the tube for maintenance purposes, or the like, with or without disturbing the location of the tube, and wherein the method is practiced by utilizing expanding bushings within the tubing, which bushings will support a shaft extending through the bushings. The bushings are caused to clamp to the internal surface of the tubing by means of an expandable split sleeve as a part of each such bushing which is normally of a smaller size than the interior of the tubing, but which is caused to expand by having a tapered inner surface which is forced upward on a tapered supporting surface by means of a threaded sleeve and, thus, is caused to expand against the interior of the tubing.
