ABSTRACT:
A process for manufacturing miniature ball bearings that reduces material loss to improve manufacturing efficiency. The process consists of obtaining an inner and outer ring blank by cutting a first blank, forging the first blank to obtain a final blank, and separating the final blank to form an outer ring blank and an inner ring blank. The outer ring blank has an outer diameter of at most 13 mm. Cutting the first blank is performed by press cutting.
