Abstract (en)

[origin: WO9924837A1] A ball bearing with an integrated sensor for detecting the relative displacement of the two bearing rings of the ball bearing (1) with respect to one another has a polar wheel (5) designed at least partially with sections and at least one sensor for scanning the polar wheel (5). In order to simplify the manufacture and at the same time increase measurement accuracy, the polar wheel (5) is made of a magnetisable material and magnetic marks, i.e. N/S marks which can be scanned by the sensor (6, 8 or 9), are provided on the polar wheel (5).
