Abstract: A seal arrangement for a shaft end. The seal arrangement includes an annular sealing lip that before use is braced on a support sleeve. The seal arrangement also includes a sensor ring that overlaps, radially inward with a flange, the sealing lip and the support sleeve, at the end facing away from the sealed space. The sensor ring is axially displaceable with respect to the sealing lip. The support ring includes at least three segments movable relative to one another and abutting against one another in the circumferential direction. The segments are fastened on the sensor ring nondisplaceably in the axial direction and displaceably outwardly in the radial direction. For easier insertion of the shaft end, the support sleeve has at the end facing the sealed space an inside diameter that is expanded in hollow conical fashion, and/or the shaft end has an outside diameter tapered in conical fashion in the opposite direction.
