Abstract
A self-aligning roller bearing includes an outer ring, an inner ring, spherical rollers, a cage having a plurality of pockets that contain the spherical rollers, and a guide ring. Each spherical roller may be rotated on an imaginary line passing through a contact point at which the spherical roller contacts an outer raceway surface and a contact point at which the spherical roller contacts an inner raceway surface. Each pocket has a clearance between the pocket and a corresponding spherical roller, and the size of the pocket is set so that the rotation of the corresponding spherical roller is limited. The guide ring has such a side-surface shape that a small clearance is ensured between the spherical roller and the guide ring even when the spherical roller is rotated, in the pocket, on the imaginary line by a maximum amount at which the rotation of the spherical roller is limited.
