ABSTRACT:
A caster bearing assembly attachable to a surface for facilitating the movement of a body along a roller plane located above the surface. The caster bearing assembly (10) includes a base part (16) mounted to the surface, a top part (18), bearings (20), and a roller assembly (22). The bearings fit within a bearing raceway (24) formed by an outer race (42) in the base part and an inner race (56) in the top part, thereby allowing the top part to fully and freely move relative to the base part. The bearings are inserted into the bearing raceway through an opening (58) extending from an exposed surface (54) of the top part to the bearing raceway. The opening is then sealed with a plug (60) having an inner surface (62) substantially matching the inner race at which the opening terminates. The roller assembly is fixedly attached to the top part so that the orientation of its rollers (26) may be varied.
