A rolling bearing having concentric bearing rings supported on one another rotatably with respect to each other by means of at least one row of rolling elements and have bearing races for the rolling elements of the at least one row of rolling elements. The invention further relates to a material transfer- or construction machine, such as a crane or cable excavator, having such a rolling bearing. Providing different bearing race corrections in different angular sectors of the bearing rings and/or providing the bearing race correction only in a fraction of the circumference of the bearing rings is advantageous over the conventional use of a bearing race correction that is constant over the circumference. A bearing race correction that is limited to one sector or that is different from sector to sector, or that is not constant over the circumference, enables the bearing rings to adapt to expected loads.
