ABSTRACT:
A hollow-bodied caster wheel is produced by casting a pair of wheel body halves with flanges which do not fit over one another at equal temperatures, cooling the inner half while keeping the outer half hot, fitting the two halves over one another in that condition, and then allowing the temperatures of the two halves to become equalized so as to cause the flanges of the two halves to bond together as the outer half shrinks during cooling. A tire is then vulcanized over the outer surfaces of the assembled wheel body halves, and bearings are press-fitted into the inner surfaces of the assembled wheel body halves to complete the wheel.
