Abstract
A self-aligning roller bearing includes an external ring with one curved external track, an internal ring with two curved internal tracks, two rows of rollers disposed between the external and internal rings, and a guide ring. The guide ring is located between the rows of rollers and is preferably configured as an circular annular disk. The guide ring has a rectangular cross section with the center line of the cross section running parallel to the bearing axis. The guide ring may also be dimensioned in such a way that the rollers are axially prestressed. The front faces of the rollers which face the guide ring are configured in a manner that the front faces only touch the guide ring at one point.
