ABSTRACT:
A sealing arrangement which includes a sealing ring with a support ring extending substantially in the radial direction and is joined in the radial direction on one end to a first sealing element that lies in sealing contact with a first machine element nonrotatably with respect thereto and in a statically sealing manner, and is joined in the radial direction on another end to a second sealing element that is placed against a second machine element rotatably with respect thereto and in a dynamically sealing manner. The first and second sealing elements are each made of an elastomeric material, and the sealing ring has, in order to sense rotational movements of the first machine element about its axis, at least one auxiliary device that can move past a rotational speed sensor. The auxiliary device may be a multipole ring, rotatable together with the first machine element about its axis, that is made of a magnetizable material. The multipole ring may have north and south poles alternating in the circumferential direction and extending in the radial direction.
