<P>PROBLEM TO BE SOLVED: To provide a bearing retainer which spreads a lubricant efficiently and uniformly in a short time over the entire space in the bearings, thereby maintaining stable lubrication performance and rotation performance of bearings over a long period of time and enabling low-cost enclosure treatment. <P>SOLUTION: The bearing retainer 11 rotatably retains a plurality of rolling elements 7 assembled at a predetermined contact angle formed between an inner and outer ring 3 and 5 which are relatively rotatably disposed opposite to each other, and revolves along between the inner and outer rings with each rolling element during the relative rotation of the inner and outer rings. The retainer is provided in a portion not intersecting with the contact angle with a lubricant introduction path 29 formed by cutting a part of the portion. The lubricant introduction path introduces a lubricant radially discharged between the inner and outer rings on the surface of the rolling elements and between the rolling element and the inner and outer rings. <P>COPYRIGHT: (C)2012,JPO&INPIT |
