A method of making a ball and roller bearing cage comprising the steps of: providing two strips of flat stock each with a plurality of equi-spaced scallops along one edge of the strip, forming each of the strips into a closed ring with the confronting edges fused together, forming a main portion of the non-scalloped edge of one ring inwardly into a frustoconical configuration, forming a main portion of the non-scalloped edge of a second ring outwardly into a frustoconical configuration, forming the frustoconical portion of the rings into a flat planar configuration normal to the scalloped surfaces, joining together the two configurations for defining spaced roller or ball receiving pockets therebetween. A method of making a ball or roller bearing cage comprising the steps of: providing two strips of flat stock each with a plurality of equispaced scallops, forming the opposite edge of the strip downwardly in a plane normal to the scalloped surface, forming the scalloped surface of one piece into a unitary ring with the uninterrupted continuous normal edge assuming a smaller diameter, forming the scalloped surface of the other strip into a unitary ring with the uninterrupted continuous normal edge assuming a larger diameter, and joining together the two rings with the balls or rolls confined between.
