Abstract:
1. A radial self-aligning rolling bearing comprising: an outer bearing ring; an inner bearing ring radially inward of the outer bearing ring, with the outer ring defining an outer raceway facing the inner ring and the inner ring defining an inner raceway facing the outer raceway; rolling elements, comprising: a plurality of bearing balls disposed between the rings and arranged around the raceways to roll in the raceways; and a plurality of spherical bearing rollers as rolling elements also disposed between the rings and rollable around the raceways, the rollers having a widest diameter; a bearing cage disposed between the rings, and the rolling elements being guided along the raceways in the cage; the bearing balls being larger in diameter than the widest diameter of the spherical rollers for enabling the balls to exclusively take up the entire rolling bearing load on the bearing when the bearing load is small.
