Abstract
A self-aligning thrust roller bearing comprising a pair of annular members having a common bearing axis and confronting coaxial raceways. The raceways are of arcuate cross-section and a plurality of symmetrical rollers are arranged in the annular space between the raceways in at least two rows. One of the arcuate raceways is a common raceway for the rollers of both rows. The other raceway comprises separate arcuate raceway sections. The axis of the rollers of each row is inclined in the same direction relative to the bearing axis. The angle of inclination of the rollers of each row are different and the mean angle between the bearing axis and the roller axis is between 20.degree. and 90.degree.. The rollers are guided without the aid of any flange engaging the roller ends.
