Abstract:
In a self-aligning roller bearing, in a longitudinal section including a center line of a spherical roller and an axis of the self-aligning roller bearing, a clearance X between an outer end surface of a spherical roller on an axially outer side of the self-aligning roller bearing and a rib portion, and a clearance Y between an inner end surface of the spherical roller on an axially inner side of the self-aligning roller bearing and a guide ring have a relation of X<Y.

Claim (Index 1):
A self-aligning roller bearing comprising:\n an outer ring having an outer raceway surface that is a recessed curve on an inner periphery of the outer ring; an inner ring having two rows of inner raceway surfaces that are recessed curves side by side on an outer periphery of the inner ring and having a rib portion at each axially outward end; a plurality of spherical rollers disposed between the outer raceway surface and the inner raceway surface in two rows side by side; a cage having a plurality of pockets that accommodate the spherical rollers to hold each row of the spherical rollers at intervals in a circumferential direction; and a guide ring disposed between the cage and the inner ring as well as between the two rows of the spherical rollers, wherein\n in a longitudinal section including a center line of the spherical roller and an axis of the self-aligning roller bearing, a clearance X between an outer end surface of the spherical roller on an axially outer side of the self-aligning roller bearing and the rib portion, and a clearance Y between an inner end surface of the spherical roller on an axially inner side of the self-aligning roller bearing and the guide ring have a relation of X<Y.
