Abstract
A double-row rolling bearing includes an outer member having two raceway surfaces on an inner circumference thereof, an inner member having two raceway surfaces on an outer circumference thereof, the inner member being arranged on an inner side of the outer member, two rows of rolling elements assembled into a space between each of the two raceway surfaces of the outer member and each of the two raceway surfaces of the inner member, and a retainer for retaining the rolling elements. Any one of the outer member and the inner member includes a pair of raceway rings, both of the pair of raceway rings being fastened with a fixing bolt and having positioning holes into which a positioning member is fit-inserted, to thereby suppress misalignment in a radial direction of the pair of raceway rings.
