A pneumatic spring and damper unit ( 1 ) has working chambers ( 2,3 ) which are filled with compressed air and are partially defined by rolled bellows or corrugated bellows. The working chambers are superimposed and connected through throttle valves, arranged inside a common pot-shaped cylindrical housing ( 4 ), and separated by a cylindrical piston ( 7 ), in such a way that one working chamber ( 2 ) is arranged on the front side of the piston and the other working chamber ( 3 ) is arranged on the rear side of the piston. The piston and the piston rod ( 5 ) are respectively sealed by roller bellows inside the cylindrical housing and guided therein, and the piston rod and the piston are interconnected by an articulation ( 6 ).
