PROBLEM TO BE SOLVED: To make lubrication on the slide part position of a retainer and raceway rings favorable, even if lubricant is dried up in a rolling bearing, and attain the long life. SOLUTION: In a rolling bearing A in which grease or oil is used as lubricant, lubricating film 5 consisting of polymer containing fluorine with functional group is formed at least on the raceway guide face of a retainer 4 or the retainer guide face of at least either of inner and outer rings 1, 2. Even if the lubricant is dried up, the slide part position of the retainer 4 with at least one of the inner and outer rings 1, 2 is lubricated by the lubricating film 5, and hence early abrasion is avoided. |
