Abstract
A molded wheel and bearing assembly includes two butt-out bearings in a molded housing forming a bearing assembly. The bearing assembly is molded into the hub of a caster wheel. The caster wheel is made by molding a hub around the bearing assembly, then molding a tread around the hub. No assembly of individual elements into the wheel is necessary.
