ABSTRACT:
A heavy duty caster for use on machines, heavy conveyances and the like has a plate the underside of which has a circular socket for a disc-shaped first thrust bearing element which is rotatably held in the socket against appreciable axial movement by a ring-shaped second bearing element bolted to the support. The first bearing element is integral with a downwardly extending shank which is bolted to the web of the inverted U-shaped frame for the wheel or wheels of the caster. A sealing ring is interposed between the ring-shaped bearing and the shank, and the support has a lubricant-admitting hole which communicates with the socket and is normally sealed by a plug.
