AirpelAnti Stiction ® cylinders have created amazing new pneumatic actuators designed for highly accurate force control. They are made of a combination of graphite pistons/borosilicate glass cylinders, each of which can be selectively matched to fit very close cylinder clearances. They have * low friction and can respond to pressures of only a few grams and less than 0.2 psi. The friction between startup and operation is almost the same, which can prevent sudden and uncontrolled startup, and provide even smoothness throughout the entire stroke of the equipment. Airpel low friction cylinder is not affected by temperature change, runs clean and does not pollute surrounding components. There is no need to interfere with the seal, and there is no lubricant or other liquid leakage. The materials used are clean and self lubricating, and have a circulation rate of *. They will not generate heat or change substantially under fast and/or continuous cycle conditions, and have a service life of millions of times.

Pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy in pneumatic transmission. There are two types of cylinders: reciprocating linear motion and reciprocating swing, as shown in the figure Cylinder. Cylinders for reciprocating linear motion can be divided into four types: single acting cylinder, double acting cylinder, diaphragm cylinder and impact cylinder.
① Single acting cylinder: there is a piston rod at one end only, and air pressure is generated by supplying air from one side of the piston. The air pressure pushes the piston to produce thrust extension and returns by spring or dead weight.
② Double acting cylinder: supply air alternately from both sides of the piston, and output force in one or two directions.
③ Diaphragm cylinder: use diaphragm instead of piston, output force in one direction only, and return with spring. Its sealing performance is good, but the stroke is short.
④ Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of high-speed (10-20 m/s) movement of the piston to do work.
⑤ Rodless cylinder: the general name of cylinder without piston rod. There are two categories: magnetic cylinder and cable cylinder.
The cylinder for reciprocating oscillation is called the oscillating cylinder. The inner chamber is divided into two parts by the blade, and the air is supplied to the two chambers alternately. The output shaft is oscillating, and the oscillating angle is less than 280 °. In addition, there are rotary cylinder, gas-liquid damping cylinder and stepping cylinder

1) Cylinder barrel
The inner diameter of the cylinder barrel represents the output force of the cylinder. The piston shall make smooth reciprocating sliding in the cylinder barrel, and the surface roughness of the inner surface of the cylinder barrel shall reach Ra0.8 μ m.
The piston of SMC and CM2 cylinders uses a combined seal ring to achieve two-way sealing. The piston and piston rod are connected by riveting without nuts.
2) End cap
The end cover is provided with an air inlet and exhaust port, and some end covers are also provided with a buffer mechanism. The rod side end cover is provided with a sealing ring and a dust ring to prevent air leakage from the piston rod and prevent external dust from mixing into the cylinder. The end cover on the rod side is equipped with a guide sleeve to improve the guiding accuracy of the cylinder, bear a small amount of transverse load on the piston rod, reduce the downward bending of the piston rod when extending, and extend the service life of the cylinder. The guide sleeve usually uses sintered oil-bearing alloy and forward inclined copper castings. The end cover used to be made of malleable cast iron. In order to reduce weight and prevent rust, aluminum alloy die-casting was often used. Brass was used for micro cylinders.

From the traditional view, the cylinder and electric actuator have always been considered as automation products in two different fields. However, in recent years, with the continuous improvement of the degree of electrification, the electric actuator has gradually infiltrated into the pneumatic field. Both of them compete and complement each other in application. In this column, we will compare the advantages of cylinder and electric actuator in terms of technical performance, purchase and application costs, energy efficiency, application occasions and market situation
Technical performance
*Compared with the electric actuator, the cylinder can work reliably under severe conditions, and the operation is simple, which can basically achieve maintenance free. The cylinder is good at reciprocating linear motion, especially suitable for the most important transmission requirement in industrial automation - linear handling of workpieces. Moreover, only adjusting the one-way throttle valves installed on both sides of the cylinder can simply achieve stable speed control, which has become the biggest feature and advantage of the cylinder drive system. Therefore, for users without multi-point positioning requirements, the vast majority prefer to use cylinders from the perspective of ease of use. At present, most of the applications of electric actuators in the industrial field require high-precision multi-point positioning, which is due to the fact that it is difficult to achieve with cylinders, so it is the second best.
The electric actuator is mainly used for rotating and swinging conditions. Its advantage lies in its fast response time and precise control of speed, position and torque through the feedback system. However, when it is necessary to complete linear movement, transmission transformation is required through mechanical devices such as toothed belt or screw rod, so the structure is relatively complex, and the working environment and professional knowledge of operation and maintenance personnel are highly required.
