PROBLEM TO BE SOLVED: To provide a double-row self-aligning roller bearing for preventing the wear of a guide ring existing between rows of rollers, when held between both rows of rollers, due to the occurrence of excessive loads in slide contact areas between each roller and the guide ring.SOLUTION: An annular groove is formed in at least one of the outer diameter face and the inner diameter face of the guide ring so that the guide ring is elastically deformed with its guide face receiving a load. When receiving the load from the rollers, the guide ring is elastically deformed to allow the load to escape, thus preventing the occurrence of excessive loads in the slide contact areas between each roller and the guide ring. |
