A plunger piston for an air spring. The air spring being active between a component which is to be cushioned by springs, in particular the vehicle frame, and a sprung component, in particular the axle carrier of a motor vehicle. The plunger piston is configured as a hollow piston which is connected to the sprung component at the lower plunger-piston end and to a pneumatic-spring bellows which can be loaded with compressed air at an upper plunger-piston head. The pneumatic-spring bellows is connected on the other side to the component which is cushioned by springs, and rolls on the outside of the plunger-piston skirt during suspension movements. The lower plunger-piston end has an open configuration and has a reinforcing element which encircles the edge region of the opening.
