PROBLEM TO BE SOLVED: To provide a self-aligning roller bearing which maintains good lubrication state between a guide ring and rolling elements and thereby inhibits wear, heat generation, and vibration.SOLUTION: A self-aligning roller bearing includes: an inner ring; an outer ring; multiple rolling elements arranged into two rows in an axial direction between the inner ring and the outer ring; a holder for holding the rolling elements at a predetermined interval in a circumferential direction; and a guide ring which is positioned between the rolling elements arranged in the two rows in the axial direction. An axial through hole is formed at the guide ring. |
