Abstract: In a heavy duty orbital caster assembly that includes a rotatable wheel unit joined to a transfer plate that pivots about a mounting post extending from a mounting plate adapted to be secured to the bottom surface of an object, the improvement comprising a pair of roller bearing assemblies that extend upwardly from the upper surface of the transfer plate adjacent to the caster wheel post as it extends through its bearing. The rollers impinge on the lower surface of the mounting plate, and serve to transfer some of the load of the supported object directly to the caster wheel, enabling the support of very heavy loads.

Abstract: A friction drive wheel for conveyor systems includes a cylindrical central disk formed of aluminum. Joined to the curved outer surface of the aluminum disk is a base layer that is cylindrical and sleeve-like and coaxial with the disk. The base layer is formed of a hard polymer (like polyurethane) material, with a hardness in the range of 75 Shore D, to eliminate torsional stress and flexure at the mechanical interface between the base layer and the central disk. A tread layer is secured about the base layer, formed of a softer polymer (like polyurethane) that is more yielding and compliant in contact with the trolley to maximize the frictional engagement. The base layer serves as a thermal insulator between the outer tread layer and the central disk, protecting the bond at the base/central disk interface.
