1. A rolling bearing comprising:
bearing rings with bearing races;
at least one row of rolling elements configured to roll on the bearing races; and
a bearing race correction configured to compensate torsions of at least one of the bearing rings under load;
wherein the bearing rings are concentric with one another and are supported on one another rotatably with respect to each other by the at least one row of rolling elements;
wherein the rolling elements are selected from the group consisting of cylindrical rollers and tapered rollers; and
wherein the bearing race correction is configured such that:
the bearing race correction is non-uniform over at least a portion of the circumference of at least one of the bearing rings;
the rolling elements are uniformly loaded at least approximately over an entire width of the rolling elements;
a line contact is established between the bearing races and the rolling elements over at least approximately the entire width of the rolling elements; and
when viewed in cross-section, the bearing races define plane contact lines which:
in the case of cylindrical rollers, are parallel to one another; and
in the case of tapered rollers, are inclined relative to one another in accordance with a taper angle of the tapered rollers.
