Bearing retainer for a roller bearing for use in a guide-post of a die-set

摘要

This invention provides a bearing retainer for a roller bearing which is used in a guide-post of a die-set. The bearing retainer has a cylindrical retainer body. The retainer body has a plurality of supporting holes to support rollers. Tongue-like portions are formed at the edge portions of each supporting hole for preventing a roller from falling out of the supporting hole. Cavities are provided between adjacent supporting holes. Each cavity permits the edge portion including the tongue-like portion to deform elastically in the direction that the aperture of each supporting hole will be enlarged on the outer side surface of the retainer body. <IMAGE>
