<P>PROBLEM TO BE SOLVED: To realize a self-aligning roller bearing with a retainer which stabilizes the attitude of each of spherical rollers 3, 3 to prevent these spherical rollers 3, 3 from skewing, enables a lubricating oil to be enough supplied, and can be operated at high speed. <P>SOLUTION: Both circumferential sides of each of columns 8a, 8a are processed into concave curved surfaces 11 opposed to a raceway of each of the spherical rollers 3, 3 via a pocket gap into which a lubricating oil can be fed. Besides, a protrusion 13 which protrudes to an end face of each of the spherical rollers 3, 3 is provided at a side face of a rim 7a. This protrusion 13 is present on the central axis of each of the spherical rollers 3 arranged inside each of pockets 9, 9. <P>COPYRIGHT: (C)2009,JPO&INPIT |
