<P>PROBLEM TO BE SOLVED: To provide a self-aligning roller bearing which has an enlarged allowable self-aligning angle without damaging load bearing capacity and workability. <P>SOLUTION: The self-aligning roller bearing includes a plurality of arrays of rolling elements 3, 3 between an outer ring 1 and an inner ring 2. A raceway surface 1a of the outer ring 1 assumes a spherical shape continuing from one edge to the other edge along the axial center c0 direction of a bearing, shapes of a plurality of arrays of raceway surfaces 2a, 2a of the inner ring 2 are symmetrical to each other via the symmetrical axis c2 vertical to the axial center c0 direction. The self-aligning roller bearing employs such a configuration that an raceway surface center line c2 passing through the maximum diameter part q2 of the raceway surface 1a of the outer ring 1 and being vertical to the axial center c0 direction is deviated to either side of the axial center c0 direction from an outer ring width bisector c1 which bisects width dimension L1 in the axial center c0 direction of the outer ring 1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
