ABSTRACT:
In a self-aligning roller bearing having a plurality of spherical rollers disposed between the track surface of an inner race and the track surface of an outer race, the bus line on the track surface of the inner race is formed by a curve comprising a plurality of radii of curvature, and there are predetermined relations among the radius of curvature of the bus line on the rolling surface of the rollers, the radius of curvature of the bus line on the track surface of the outer race, the radius of curvature of the bus line on the track surface of the inner race corresponding to the axially central portion of each roller and the radii of curvature of the bus lines on the track surface of the inner race corresponding to the axial end portions of each roller.
