Abstract: A rolling element bearing having a first ring element, a second ring element (3), a plurality of rolling elements arranged in a space between the first and the second ring elements such that the first and the second ring elements can rotate relative each other around a rotational axle. The bearing further includes a sealing ring for sealing off a circumferential opening of the space between the first and the second ring element. The sealing ring is connected to the first ring element and further arranged to rotate relative the second ring element of the rolling element bearing. The sealing ring provides a power generating system that provides at least one pick-up element arranged to generate electrical power when the rolling element bearing rotates. The power generating system is located completely within the circumferential opening of the space.

Abstract: A rolling element bearing having first and second bearing rings and at least one row of rolling elements disposed between raceway surfaces of the bearing rings. The bearing further includes at least one sensor provided on a sensing surface of the first bearing ring, and a signal-carrying cable in connection with the sensor. The cable provides a cable connector, which fits into a socket. The socket is integrated in a recess provided in an external surface of the first bearing ring. The recess is in communication with the sensing surface and a signal coupling is provided between the sensor and the socket. One of the cable connector and the socket has an angled body section angled with a first angle ? relative to a longitudinal axis of the recess, such that the cable is guided out of the recess at an angle to a normal of the external surface.
