The invention relates to a sealing device () for two components () which are mounted on each other and are displaceable in relation to each other, in particular of a rotary bearing (), with an elastomer part () which is arranged in a stationary manner on one of the components () and has at least one sealing surface () providing a seal in relation to a mating sealing surface () of the other component (). In order to reduce the wear and frictional resistance of the sealing device (), at least one sealing surface () is arranged so as to be controllable externally in respect of the press-on force thereof in relation to the mating sealing surface ().

Sealing device and rotary bearing therewith

A wheel bearing device for a motor vehicle, having an inner ring arrangement, formed for rotationally fixed reception of a first rotary partner, particularly an axle stump, or a shaft, an outer ring arrangement, which is connected and/or connectable and rotationally fixed with a second rotary partner, a multitude of rolling elements, which roll between the inner ring arrangement and the outer ring arrangement, so that inner ring arrangement and outer ring arrangement and/or the rotary partners are rotatable against each other, and an electric sensor device, which, using mechanical contact, is arranged and/or formed for detecting an operating status of the wheel bearing device. The sensor device has a stationary sensor element and a rotating sensor element, which can work together to form the mechanical contact. One of the sensor elements is connected with the inner ring arrangement without the interposition of the first rotary partner.
