ABSTRACT:
There is realized a self-aligning roller bearing with retainer that stabilizes the orientation of spherical rollers and prevents these spherical rollers from skewing, and which can be rotated at high speed, and furthermore which enables efficient lubricant feed into pockets9.By rotating a turning tool14as it revolves, the surfaces on both sides in the circumferential direction of respective column sections are processed into concave curved surfaces that oppose a rolling surface of the respective spherical rollers across a pocket clearance into which lubricant oil can be fed. The length of the column sections8cis less than the length in the axial direction of the spherical rollers, and greater than a half of the length, and an end portion of the side surface in the circumferential direction of the respective column sections8cprojects further in the circumferential direction than an intermediate portion thereof, and the spherical rollers are embraced in the pockets9.
