Abstract
The utility model relates to an air cylinder which comprises a front end cap, a cylinder barrel, a piston rod, a piston and a rear end cap. A first seal ring is arranged between the piston and the cylinder barrel, and is arranged on the piston. A second seal ring is arranged between the front end cap and the cylinder barrel, and is arranged on the front end cap. A third seal ring is arranged between the piston rod and the piston, and is arranged on the piston. A fourth seal ring is arranged between the cylinder barrel and the rear end cap, and is arranged on the rear end cap. The air cylinder is simple in structure and low in cost; and the seal rings are arranged on joints of all parts inside the air cylinder, accordingly gas tightness of the air cylinder is greatly improved, and safety performance is enhanced.
