ABSTRACT:
An improved trolley wheel assembly and method therefor. The assembly is useful in conveyor applications especially where sanitary conditions must be maintained such as in the food processing industry. The assembly has high load bearing capabilities and includes an antifriction plastic wheel extending about a pair of annular, metallic outer bearing race rings positioned back to back within a central opening of the wheel. The wheel extends around edges of the rings to maintain their axial positions and extends into recesses in the rings to prevent wear-producing rotation between the rings and wheel. The method includes prepositioning the rings in back-to-back alignment and placing or forming by molding the wheel therearound.
