摘要： A self-aligning roller bearing is provided which includes an inner ring having a double-row raceway, an outer ring having a double-row integral and spherical raceway, a plurality of rollers incorporated between the inner ring raceway and the outer ring raceway on a double-row basis, and a retainer for rotatably retaining the rollers. Processing marks crossing each other are formed on a raceway surface of the spherical raceway of the outer ring. The processing marks are cut substantially straightly at a predetermined crossing angle to the circumferential direction of the raceway surface. The surface roughness of the raceway surface is substantially constant in the axial direction and the circumferential direction thereof at least in a part in contact with the roller.
