an air spring having an air spring cover and a rolling piston;
a shock damper integrated with the air spring and having a damper tube, and a piston rod receivable within the damper tube;
a rolling bellows, composed of an elastomer material, secured pressure-tightly between the air spring cover and the rolling piston thereby delimiting a variable volume pressure chamber filled with compressed air, and wherein the rolling bellows rolls on the rolling piston with a rolling fold being formed;
a damper bearing accommodated in a bearing socket of the air spring cover and connected to the piston rod, wherein the damper bearing comprises a supporting piece, an elastomer body, and a sleeve;
a closure element inserted in the bearing socket above the damper bearing;
