ABSTRACT:
A double row self-aligning roller bearing in which spherical rollers are arranged in double rows between an inner ring and an outer ring, characterized in that the curvature radius of the ridge line of the spherical roller in one row is R1, the curvature radius of the ridge line of the spherical roller positioned in the other row is R2, the curvature radius of the inner ring track surface being in contact with the spherical roller in one row is N1, and the curvature radius of the inner ring track surface being in contact with the spherical roller in the other row is N2, a relation such that N1/R1>N2/R2is satisfied.
