Abstract

The angular contact roller bearing has an outer bearing ring, an inner bearing ring, a plurality of ball rollers arranged between the rings, and a bearing cage. The ball rollers in the two adjacent rows have pressure angle axes extending parallel to one another and are arranged directly one next to the other with their side faces point toward one another. Adjacent ball rollers in the two rows are arranged on a common rotational axis. The ball rollers have diameters and widths which are dimensioned in such a way that envelope cones which form tangents with all the ball rollers at their diameters are arranged with their cone tips precisely at the intersection point of the common rotational axes of the bearing longitudinal axis.
