Abstract
The invention relates to an anti-friction bearing comprising a first bearing race, a second bearing race and a plurality of anti-friction bodies that are located between the first bearing race and the second bearing race. According to the invention, the anti-friction bearings are arranged in several rows, which are asymmetrical in the longitudinal direction of the anti-friction bearing in relation to any plane that runs perpendicularly to said longitudinal direction of the anti-friction bearing.

An anti-friction bearing, comprising:
- a first bearing ring
- a second bearing ring;
- and
- a plurality of rolling bodies arranged between the first bearing ring and the second bearing ring,
- wherein the rolling bodies are ball bearings arranged in an uneven number of rows and the rows are arranged asymmetrically in a longitudinal direction of the anti-friction bearing about an arbitrary plane which is perpendicular to the longitudinal direction of the anti-friction bearing, and
- wherein the rolling bodies of each row have different diameters resulting in different pitch circle diameters for each of the rows.
