<P>PROBLEM TO BE SOLVED: To provide a self-aligning roller bearing which can prevent an outer peripheral side corner part of a guide ring from contacting with an inside end surface in the axial direction of spherical rollers. <P>SOLUTION: The self-aligning roller bearing includes an outer ring 1 having an outer raceway surface 11, an inner ring 2 having inner raceway surfaces 21 by two rows, the spherical rollers 3 arranged in two rows between the outer raceway surface 11 and the inner raceway surfaces 21 of the two rows and arranged in a plurality in the peripheral direction with respective rows, an annular cage 5 for holding a plurality of spherical rollers 3 of the respective rows and an annular guide ring 6 arranged between the rows of the spherical rollers 3 and 3 of the two rows. The spherical rollers 3 have a chamfering part 33 constituted of a convex curved surface. The guide ring 6 has on both sides a side surface 7 contacting with the chamfering part 33, and a width in the axial direction between side surfaces 7 and 7 of both sides becomes gradually small toward the outer peripheral side from the inner peripheral side. <P>COPYRIGHT: (C)2012,JPO&INPIT |
