An air spring includes a bellow at least partially delimiting at least one working chamber that is constructed and arranged to be filled with compressed air. A guide tube surrounds at least a portion of the bellow. A piston is associated with the bellow. The bellow is constructed and arranged to roll with respect to an outer surface of the piston and an inner surface of the guide tube. At least one of the guide tube and the piston includes a lamination comprising an inner layer of material coupled to an outer layer of material so as to cause internal friction and thus a dampening of vibrations inside the material.
