The inner diameter of the FESTO cylinder barrel represents the output force of the cylinder. The piston should perform smooth reciprocating sliding inside the cylinder, and the surface roughness of the inner surface of the cylinder should reach Ra0.8um. For steel cylinder barrels, the inner surface should also be plated with hard chromium to reduce friction resistance and wear, and to prevent rust. In addition to using high carbon steel pipes, the cylinder material is also made of high-strength aluminum alloy and brass. Small cylinders use stainless steel pipes. For cylinders with magnetic switches or cylinders used in corrosion-resistant environments, the cylinder barrel should be made of materials such as stainless steel, aluminum alloy, or brass.Air Cylinder Barrel.

The FESTO cylinder cylinder piston adopts a combination sealing ring to achieve bi-directional sealing, and the piston is connected to the piston rod by a rivet without the need for nuts. There are intake and exhaust ports on the FESTO cylinder end cover, and some also have buffer mechanisms inside the end cover. There are sealing rings and dust rings on the end cover of the rod side to prevent air leakage from the piston rod and prevent external dust from entering the cylinder. There is a guide sleeve on the end cover of the rod side to improve the guiding accuracy of the cylinder, withstand a small amount of lateral load on the piston rod, reduce the downward bending when the piston rod extends, and extend the service life of the cylinder. The guide sleeve usually uses sintered oil containing alloy and forward leaning copper castings. In the past, malleable cast iron was commonly used for end caps. In order to reduce weight and prevent rust, aluminum alloy die casting was often used, and brass material was used for micro cylinders. The FESTO cylinder piston is a pressurized component in the cylinder. To prevent mutual gas leakage between the left and right chambers of the piston, a piston sealing ring is installed. The wear-resistant ring on the piston can improve the orientation of the cylinder, reduce the wear of the piston sealing ring, and reduce frictional resistance. The wear-resistant ring is made of materials such as polyurethane, polytetrafluoroethylene, and sandwich synthetic resin. The width of the piston is determined by the size of the sealing ring and the necessary length of the sliding part. The sliding part is too short, which can easily cause early wear and jamming. The material of the piston is commonly aluminum alloy and cast iron, while the piston of a small cylinder is made of brass. The FESTO cylinder piston rod is the most important load-bearing component in the cylinder. High carbon steel is usually used, with a surface treated with hard chromium plating, or stainless steel is used to prevent corrosion and improve the wear resistance of the sealing ring. FESTO cylinder seal: The sealing of components in rotating or reciprocating motion is called dynamic seal, and the sealing of stationary parts is called static seal.ADN Pneumatic Cylinder Barrel.
