Abstract
A sheet-metal piston rod guide for a piston-cylinder unit in which a piston rod is axially movable, includes a slide bush which is centered by a guide sleeve which adjoins a closure ring which delimits the working chamber and in turn merges into an axial casing. The axial casing centers the entire piston rod guide. A piston rod seal surrounds the piston rod and seals the working chamber. The guide sleeve is supported in the axial and radial directions against a bearing ring which bears the piston rod seal and extends in the radial direction. The bearing ring has a radial support surface with respect to the casing so that the casing, the closure ring, the guide sleeve, and the bearing ring form a force bearing arrangement which is closed with regard to the bearing of forces.
