Abstract

A reduction in the setting of rollers in a self-aligning roller bearing is provided. The self-aligning roller bearing has inner and outer bearing rings and rollers arranged at least in one roller row. The rollers have a curved lateral surface the direction of the rotation axis and has a radius, and roll over curved raceways of the bearing rings. The raceways are each assigned a groove point around which the curved raceway extends at a radial distance in the direction of the rotation axis. A pressure line intersects the rotation axis at an angle of 90° at a point where these rollers have their largest roller diameter, and the radius of the curved lateral surface is smaller than both radial distances.
