Abstract

The invention relates to an angular contact roller bearing having an inner ring and an outer ring, between which two or more raceways for a plurality of rolling elements are formed, the rolling elements being designed to roll in their respective raceways in the circumferential direction of the angular contact roller bearing, and the raceways and the rolling elements having cross-sections corresponding to one another at least approximately. A cross-section of a rolling element containing the central longitudinal axis has an at least approximately rectangular design and an imaginary diagonal through the cross-section of the rolling element which for all rolling elements on a raceway of the angular contact roller bearing is arranged on an imaginary surface at least approximately in the form of a cylindrical casing. The ratio of a transverse dimension of the rolling element to its length is characteristic of an angle at which the raceway of the rolling element is inclined relative to the central longitudinal axis of the angular contact roller bearing.
