Angular ball bearing arrangement

An angular contact ball bearing arrangement having comprising:

• a first raceway element having a first raceway,
• a second raceway element having a second raceway, and
• a plurality of balls between the first raceway element and the second raceway element in contact with the first and second raceways,
• wherein, when viewed in cross section through one ball of the plurality of balls the angular contact ball bearing arrangement is divided into a first quadrant, a second quadrant, a third quadrant and a fourth quadrant arranged clockwise by an axis of rotation of the one ball and an axis perpendicular to the axis of rotation of the one ball,
• wherein the one ball contacts the second raceway at a first contact point in the first quadrant and a second contact point in the second quadrant and contacts the first raceway at a third contact point in the third quadrant and a fourth contact point in the fourth quadrant,
• wherein the second raceway lies in the first quadrant and in the second quadrant and the first raceway lies in the third quadrant and in the fourth quadrant,
• wherein a centre point of a radius of curvature of a portion of the second raceway in the first quadrant lies in the third quadrant,
• wherein a centre point of a radius of curvature of a portion of the second raceway in the second quadrant lies in the fourth quadrant,
• wherein a centre point of a radius of curvature of a portion of the first raceway in the third quadrant lies in the first quadrant,
• wherein a centre point of a radius of curvature of a portion of the first raceway in the fourth quadrant lies in the second quadrant,
• wherein the first contact point and the second contact point are offset from the axis perpendicular to the axis of rotation of the one ball and lie on the second raceway within an angle of ±10° from the axis perpendicular to the axis of rotation of the one ball, and
• wherein the third contact point and the fourth contact point are offset from the axis perpendicular to the axis of rotation of the one ball and lie on the first raceway within an angle of ±10° from the axis perpendicular to the axis of rotation of the one ball.
