A cylinder-piston rod unit includes a sealing ring adjacent at least one end of the cylinder for forming a fluid-tight seal between the cylinder and the piston rod. The sealing ring includes a substantially axially extending sleeve portion and a substantially radially extending flange portion. A sealing-pressure application ring, which is subject to a circumferential tensioning force over at least the lower part of the operating temperature range of the sleeve portion, surrounds the sleeve portion and exerts a radial sealing force against the sleeve portion. The sealing ring is secured to the cylinder by the flange portion. |
