Abstract
The rolling bearing has a first bearing ring, a second bearing ring and a plurality of rolling bodies which are arranged between the first bearing ring and the second bearing ring. The rolling bodies are arranged in at least four rows. At least two rows have a first reference diameter and at least two further rows have a second reference diameter which is different from the first reference diameter, and those rows which have the same reference diameter are arranged symmetrically with respect to a predefined plane which is aligned perpendicular to a longitudinal direction of the bearing.

A rolling bearing, comprising:
- a first bearing ring;
- a second bearing ring radially inside the first bearing ring;
- and
- a plurality of rolling bodies arranged between the first bearing ring and the second bearing ring,
- wherein the rolling bodies are arranged in at least four rows, at least two rows have a first pitch circle diameter, at least two further rows have a second pitch circle diameter which differs from the first pitch circle diameter, and the at least two rows, which have the first pitch circle diameter and the at least two further rows, which have the second pitch circle diameter are arranged symmetrically with respect to a plane which is perpendicular to a longitudinal direction of the bearing,
- wherein the bearing has a flange-side outer diameter which is greater by more than 6 mm than a sum of a flange-side pitch circle diameter and a rolling body diameter of a flange-side rolling bodies,
- wherein a pitch circle diameter of an inner row of the rolling bodies is greater by more than 3.5 mm than a bore diameter of the rolling bearing, and
- wherein the at least two rows are outer rows, which have a first pressure angle and a fourth pressure angle and the at least two further rows are inner rows which a second pressure angle and a third pressure angle, the first pressure angle and the fourth pressure angle of the outer rows are greater than the second pressure angle and the third pressure angle of the inner rows.
