ROLLER BEARING CAGE, ROLLER BEARING, AND METHOD FOR PRODUCING ROLLER BEARING CAGE
摘要:
In a step of forming a roller bearing cage (13) including a first roller stopper part (16a) provided on the radial inner side to prevent a roller from escaping to the radial inner side, and a second roller stopper part (17a) provided on the radial outer side to prevent the roller from escaping to the radial outer side, on wall surfaces (16b) and (17b) opposed to a pocket (20), respectively, each of the first and second roller stopper parts (16a) and (17a) is formed by a process only from the one radial side with a jig (60).
