Patent ID: 7427163

Claim:
A self-aligning antifriction bearing comprising at least a first row of rolling elements and comprising a second row of rolling elements adjacent to the first row of rolling elements, each of the rows having balls and rollers disposed peripherally about a center axis of the self-aligning antifriction bearing and the balls in this case having a smallest external diameter which is greater than a largest external diameter of the rollers; the self-aligning antifriction bearing further comprising, respectively, an imaginary first rolling contact plane of the balls per row, which plane is concentric to the center axis and runs centrally through the balls, and comprising, respectively, an imaginary second rolling contact plane of the rollers per row, which plane is concentric to the center axis and intersects the rollers at the largest external diameter, in each of the rows the first rolling contact plane being axially distanced from the second rolling contact plane along the bearing center axis.
