Abstract: The invention relates to an air spring having: a rolling bellows (1) with an opening which has a bead (2) reinforced by a core (3) and a rolling piston (4) with a seat (5) for the rolling bellows (1) and a support shoulder (7) for the rolling bellows (1), wherein when the rolling bellows (1) is in the mounted state, its end assigned to the rolling piston (4) is connected to the rolling piston (4) in an airtight manner by a clamping fit between the bead (2) and the seat (5) of the rolling piston (4), and the bead (2) of the rolling bellows (1) rests at least partly on the support shoulder (7), wherein the rolling piston (4) is made of a thermoplastic material. The object of the invention is to improve an air spring of the type outlined above such that the bellows (1) can very reliably and simply be prevented from slipping off the piston (4), in particular in view of the use of plastic as the piston material.
