Rolling bearing with monitoring device

A rolling bearing comprising:

• two bearing rings;
• rolling elements running between the two bearing rings;
• and
• a sensor for detecting movements and/or positions of the two bearing rings relative to one another,
• wherein the sensor is fastened to one of the two bearing rings and is directed towards a measurement surface on the other of the two bearing rings, wherein the measurement surface comprises a contour projection projecting towards the sensor and/or a contour recess open towards the sensor in the form of a groove or a blind hole, wherein the contour projection and/or the groove influences a measurement signal of the sensor and the movement of which relative to the sensor transverse to a main signal direction of the sensor modifies the measurement signal of the sensor,
• wherein the sensor is configured to determine radial movements of the two bearing rings relative to one another, wherein the contour projection and/or the contour recess is on an axial surface of the other of the two bearing rings, and wherein the contour projection or the contour recess projects or is recessed in the axial direction from or into the axial surface, respectively.
