A pneumatic suspension system forming a McPherson strut has a pneumatic suspension pot with an integrated strut bearing, pneumatic suspension bellows made of an elastomer material, a pneumatic suspension piston, an outer guide and a damping device. The essential features of the system are: the pneumatic suspension bellows have an inclined loop whose effective diameter defined by the top and bottom extremes of the loop is substantially perpendicular to the force application line. The outer surface of the pneumatic suspension piston has cylindrical and conical parts which form a rolling contour which is not rotationally symmetrical with respect to the damping axis and which is adapted to the effective diameter of the inclined loop of the pneumatic suspension bellows in that the effective diameter is substantially parallel to the preferably rounded edges of the rolling contour. The outer guide completely surrounds the inclined loop of the pneumatic suspension bellows during both rebound and spring deflection.
