A sealing arrangement including a sealing ring with a support ring extending substantially in a radial direction. The support ring is joined in the radial direction to a first sealing element that lies in contact with and is nonrotatable with respect to a first machine element to form a static seal. The support ring is also joined in the radial direction to a second sealing element that is placed against a second machine element rotatably with respect to the second machine element to create a dynamic seal. 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 can be a multipole ring made of a pasty, hardenable, and magnetizable material that is arranged as a intermediate layer of film-like thinness on the side of the support ring facing the rotational speed sensor. The multipole ring has north and south poles alternating in the circumferential direction and extending in the radial direction, and the multipole ring is completely covered by the elastomeric material of the first and/or second sealing elements. |
