Abstract: A pneumatic spring-vibration damper unit is provided for absorbing shocks on wheels and chassis parts of motor vehicles. A variable air chamber is delimited by a rolling bellows which is disposed between a first subassembly that is fixed to the vehicle body and is provided with a vibration damper system and a second subassembly that is fixed to the vehicle chassis and is movable therewith. A piston rod connects the first subassembly located at the vehicle body end and the second subassembly located at the chassis end and whose free end located at the vehicle body end is accommodated inside a cylinder tube of the vibration damper system so as to be longitudinally movable by means of a piston. The piston rod (8) is guided within the cylinder tube (6) of the vibration damper system (2) so as to be longitudinally movable with the aid of a drag bearing arrangement (13).
