ABSTRACT:
The rotating stem mount has an anchor block and a lag screw extending through the anchor block for mounting the anchor block to a stationary surface. A guide bearing is mounted on a circular shoulder on the anchor block near the base end of the anchor block. The outer race of a thrust bearing is retained to the load end of the anchor block in axial alignment with the anchor block by means of a bearing retainer. A cylindrical housing encloses the thrust bearing, the guide bearing and the anchor block. The housing has a diametrical partition therein in a mid-region thereof. A bolt retains the diametrical partition to the inner race of the thrust bearing. The housing further has an internal circular step in its base end, and that circular step fitly encloses the guide bearing. A stem-like member is mountable to the load end of the housing.
