Abstract

The invention relates to a rolling bearing with two bearing rings and rolling elements running between same, and a sensor for detecting movements and/or positions of the bearing rings relative to one another, wherein the sensor is fastened to one of the bearing rings and is directed towards a measurement surface on the other bearing ring, wherein said 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 blind hole, which projection or groove influences the measurement signal of the sensor and the movement of which relative to the sensor transverse to the main signal direction of the sensor modifies the measurement signal of the sensor.
