Abstract A rotatable load-bearing pendant of the type commonly used in conjunction with an overhead conveyor system is provided comprising a cylindrical shaft having one end threaded and the other curved to provide a fastening means in the form of a hook. A disc having a hole therein constituting a shaftway is adapted to rotatably receive the shaft such that the threaded portion of the shaft and the shaftway provide a lateral bearing. A locknut is employed to captivate the disc on the shaft such that the bottom side of the disc and the top side of the locknut form a vertical bearing. Additional holes are provided in the disc such that they partially overlap the shaftway to thereby form small vertical slots in the side of the shaftway which cooperate with the threaded portion of the shaft to provide a self-cleaning action as the disc is rotated relative to the shaft. A U-shaped hook is symmetrically connected to the underside of the disc in order to provide means for attaching a load to the disc.
A rotatable load-bearing pendant which is self-cleaning and does not require lubrication, comprising: p1 a shaft having threads at one end and fastening means at the other end; a disc having a hole therein constituting a shaftway adapted to rotatably receive the threaded portion of said shaft and form therewith a lateral bearing, said disc having at least one additional hole therein partially overlapping said shaftway to thereby form a vertical slot in at least one portion of the shaftway; means at said threaded end of said shaft for captivating said disc on said shaft and forming therewith a vertical bearing; and means for attaching a load to said disc.
