ABSTRACT:
In a double row automatic center adjusting roller bearing at least one of the raceway surfaces of an inner race and an outer race and a rolling surface of a roller is worked to have different surface roughnesses along the axial direction of the roller bearing. For the inner race having a pair of inner raceway surfaces, in each inner raceway surface, a contact surface portion which is in contact with the rollers at a bearing center side is formed to have smaller surface roughness than that of a contact surface portion which is in contact with the rollers at a bearing side surface side to thereby prevent the generation of a large negative skew angle of the roller.
