Abstract

An optimized ball bearing for an electric vehicle having an inner ring or an outer ring with a radial thickness at least equal to the diameter of the balls is provided with at least one annular recessed surface to reduce the mass of the ring. Each annular recessed surface may be formed as chamfer, a fillet or a groove. The annular recessed surfaces may be provided on both the inner and outer rings to improve lubrication flow.
