Abstract

PURPOSE: To scheme out stabilization of contact and to minimize sound and heat generation in such a way that a bar part of a cage after pocket punching is expanded out by plastic deformation along the direction of the length of the bar part, contact position with rolling materials is expanded out until it reaches practically the middle part in the diametral direction.
