PROBLEM TO BE SOLVED: To provide a double row roller bearing suitable for a shaft where radial load distribution is axially changed. SOLUTION: In the double row roller bearing constituted that a plurality of rows of roller bearings having an inner ring where a raceway surface is formed at an outer periphery part; an outer ring where a race surface is formed at an outer peripheral part; and a plurality of rows of rollers incorporated between the raceway surface of the inner ring and the raceway surface of the outer ring are axially arrayed, a plurality rows of roller bearings are constituted such that a plurality of roller bearings different in an allowable radial load are incorporated. This constitution can prevent abnormal heating of a specified row of the roller bearing and the occurrence of seizure by differentiating the allowable radial load of each row of bearing according to a radial load applied on the row.
