ABSTRACT:
A method of preloading the upper ball bearing of a spin casting machine. Spring force is used to lift the inner bearing race and preload the bearing upward. Spring force is applied against a bearing collar which rests against the lower surface of the inner bearing race. The rotor shaft has a sliding fit within the inner race and the bearing collar. The rotor shaft is frictionally coupled to the inner bearing race by the force of the preloading spring through the bearing collar.
