Abstract

A sliding bearing includes at least one bearing inner ring and at least one bearing outer ring configured to rotate relative to each other about an axis (a), where the rings each include at least one sliding surface, the sliding surfaces being configured to slide along each other, and where the contact surface formed by the mutually contacting sliding surfaces has a maximum contact diameter (DK). At least parts of the sliding surfaces in a radial section have a radius of curvature (rB), the radius of curvature (rB) has a centerpoint (M) located at an offset (b) from the axis (a), and the offset (b) is at least 5% of the radius of curvature (rB).
