ABSTRACT:
A pinless caster assembly comprising a first substantially "T"-shaped part and a second substantially ring-shaped solid part, said first and second parts interfitting with bearing elements and when interfit providing races for the bearing elements and the caster assembly, said first and second part being machined from solid material of predetermined metallurgical characteristics, said first part having disposed therewith a first one-half raceway, for receiving load-carrying bearings in use, and a second one-half raceway for receiving swivel bearings in use, said second part having disposed therewith a third one-half raceway for receiving load-carrying bearings in use for mating with the first one-half raceway disposed with the first part and thereby providing a load-carrying race of the caster assembly, said second part also having disposed therewith a fourth one-half raceway for receiving swivel bearings in use and for mating with the second one-half raceway disposed with the first part and thereby providing a swivel race of the caster assembly, wherein the first and second parts interfit to provide the caster assembly, said caster assembly having provided therewith an opening extending into the swivel race to enable bearings to be loaded into the caster raceway in use, said opening being closed by a closure so as not to interfere with the abilities of the bearings contained within the raceway, wherein the raceway formed from interfitting the first and third one-half raceways disposed with the first and second parts contains the load-carrying bearings for the caster assembly, and wherein the raceway formed from interfitting the second and fourth one-half raceways disposed with the first and second parts contains the swivel bearings for the caster assembly, the caster assembly so formed having substantial resistance to wear and fatigue as required in heavy duty applications.
