摘要： A seal includes a supporting ring and at least one sealing ring. The at least one sealing ring has a sheath. The at least one sealing ring and the supporting ring are interconnected. The supporting ring has an outer periphery and is, at least in part, surrounded on the outer periphery by the sheath of the at least one sealing ring in a radial direction. The at least one sealing ring has at least one dynamically loaded sealing lip, which is arranged on a side of the at least one sealing ring facing radially away from the sheath. The at least one sealing ring includes an electrically conductive polymer material. The sheath and the sealing lip transition into one another as one piece.
