Abstract
A method for fabricating a spindle housing with a ball bearing has the following steps: positioning the ball bearing in a cavity of a molding tool in a condition that a pre-load is provided to eliminate an internal clearance of the ball bearing, and injecting synthetic resin within the cavity of the molding tool after relative movement of the outer race and inner races of the ball bearing due to the pre-load.
