In order to achieve direct digital data recording and reliable and space saving and cost saving recording of the status of an antifriction bearing, in particular a wheel bearing for motor vehicles, sensors record the rotational speed and acceleration of the wheels and driving and/or braking forces. The sensors are microsensors in the form of microswitch arrays, at least one of which is attached to the rotating ring of the bearing, and the generated signals are compared with stored basic patterns or with the signals of an identical or similar microsensor arranged on the stationary ring of the bearing and/or are evaluated.

Antifriction bearing including microsensor for determining parameters,

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.
