PROBLEM TO BE SOLVED: To provide a self-aligning roller bearing excellent in fluidity of lubricant in a radial direction of a bearing, and thereby capable of suppressing heating, abrasion and vibration even when the bearing rotates at high speed.SOLUTION: A self-aligning roller bearing includes: an inner ring; an outer ring; a plurality of rolling bodies arrayed in two rows in an axial direction between the inner ring and the outer ring; and a holder having a pocket for holding the rolling bodies with a predetermined interval in a circumferential direction. The pocket of the holder is defined by an annular part and a columnar part extending from the annular part in the axial direction. In the columnar part, a radial hole penetrating in a radial direction is formed.SELECTED DRAWING: Figure 1 |
