ABSTRACT:
A rolling contact bearing with rotational speed measuring device, in particular a wheel bearing for motor vehicles for telemetric transmission of energy and signal between bearing and environment, insensitive to tolerances of the bearing and its surrounding parts, with simple and cost-effective construction and small dimensions. A first telemetry unit is integrated in the inter-ring seal. It comprises pulse transmitter, rotational speed sensor, telemetry electronics and a miniature coil, which is inductively coupled with a further telemetry unit, which is fitted axially outside the bearing, and which supplies the first telemetry unit with energy and receives its signals.
