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.
