Disclosed is an improved air suspension that prevents damage and/or failure of a component of an air spring, such as an air sleeve. The air suspension includes a damper including a cylinder and a piston rod slidably disposed in the cylinder, an air spring hermetically connected to an outside of the cylinder, an upper mount which secures the damper and the air spring to a vehicle frame, and a rotational sealing part disposed between the air piston and the cylinder and allowing relative rotation of the air spring and the cylinder while maintaining air-tightness between the air piston and the cylinder. The air suspension may prevent damage and/or failure of components of an air spring, such as an air sleeve, by undesired force or moment such as torsional rotational force applied to the air spring in the course of driving the vehicle.
