Aventics Cylinder Structure:

An Aventics cylinder consists of a cylinder barrel, end caps, piston, piston rod, and seals. Its internal structure is shown in the diagram "SMC Cylinder Schematic":

1) Cylinder Barrel

The inner diameter of the cylinder barrel determines the output force. For the piston to slide smoothly back and forth within the cylinder barrel, the surface roughness of the inner surface should reach Ra0.8μm.

SMC and CM2 cylinders use a combination sealing ring on the piston to achieve bidirectional sealing. The piston and piston rod are connected by press-fitting, eliminating the need for nuts.

2) End Caps

The end caps have inlet and outlet ports, and some also have a buffer mechanism inside. The rod-side end caps have sealing rings and dustproof rings to prevent air leakage from the piston rod and to prevent external dust from entering the cylinder. A guide sleeve is provided on the piston rod end cap to improve the guiding accuracy of the cylinder, bear a small amount of lateral load on the piston rod, reduce the downward bending of the piston rod when it extends, and extend the service life of the cylinder. The guide sleeve is usually made of sintered oil-impregnated alloy or forward-inclined copper casting. End caps were previously commonly made of malleable cast iron, but to reduce weight and prevent rust, aluminum alloy die casting is often used; micro cylinders sometimes use brass.

3) Piston

The piston is the pressure-bearing part in the cylinder. A piston seal ring is provided to prevent air leakage between the left and right chambers of the piston. The wear ring on the piston improves the guiding performance of the cylinder, reduces the wear of the piston seal ring, and reduces frictional resistance. Wear rings are often made of polyurethane, polytetrafluoroethylene, or fabric-reinforced synthetic resin. The width of the piston is determined by the size of the seal ring and the necessary length of the sliding part. A sliding part that is too short can easily cause premature wear and jamming. Pistons are commonly made of aluminum alloy and cast iron; pistons in small cylinders are sometimes made of brass. (See Figure 2)

4) Piston Rod

The piston rod is the most important force-bearing part in the cylinder. High-carbon steel with a hard chrome plating or stainless steel are typically used to prevent corrosion and improve the wear resistance of the sealing rings.

5) Sealing Rings

The sealing of components in rotating or reciprocating motion is called dynamic sealing, while the sealing of stationary parts is called static sealing.

The main methods of connecting the cylinder barrel and end cover are as follows:

Integral type, riveted type, threaded connection type, flange type, and tie rod type.

6) During cylinder operation, the piston is lubricated by oil mist in compressed air. A small number of cylinders are lubrication-free.

Aventics Cylinder Working Principle:

Aventics cylinders determine the thrust and pull forces on the piston rod based on the required working force. Therefore, when selecting a cylinder, a slight margin in output force should be allowed. If the cylinder diameter is too small, the output force will be insufficient, and the cylinder will not function properly; however, if the cylinder diameter is too large, it will not only make the equipment bulky and expensive, but also increase air consumption, resulting in energy waste. When designing fixtures, force-multiplying mechanisms should be used as much as possible to reduce the size of the cylinder.

Aventics Cylinders

Below is the formula for calculating the theoretical output force of a cylinder:

F: Theoretical output force of the cylinder (kgf)

F′: Output force at 85% efficiency (kgf) -- (F′=F×85%)

D: Cylinder diameter (mm)

P: Working pressure (kgf/cm²)

Example: What is the theoretical output force of a cylinder with a diameter of 340mm and a working pressure of 3kgf/cm²? What is the actual output force?

Connect P and D, find the points on F and F′, and we get:

F=2800kgf; F′=2300kgf

A cylinder is a container in an internal or external combustion engine that houses a piston, allowing it to reciprocate up and down. It consists of a cylinder barrel, end caps, piston, piston rod, and seals. Cylinders are classified into two types: those that perform reciprocating linear motion and those that perform reciprocating oscillation. During operation, the piston is lubricated by oil mist in compressed air.

A pneumatic actuator is a pneumatic actuator that converts the pressure energy of compressed gas into mechanical energy. Cylinders are classified into two types: those that perform reciprocating linear motion and those that perform reciprocating oscillation (see figure). Cylinders that perform reciprocating linear motion can be further divided into four types: single-acting, double-acting, diaphragm, and impact cylinders.

① Single-acting cylinder: Has a piston rod at only one end. Air is supplied from one side of the piston, generating pressure that pushes the piston outward. It returns to its original position using a spring or gravity.

② Double-acting cylinder: Air is supplied alternately from both sides of the piston, outputting force in one or two directions.

③ Diaphragm cylinder: Uses a diaphragm instead of a piston, outputting force in only one direction and returning to its original position with a spring. It has good sealing performance but a short stroke.

④ Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of the piston's high-speed (10-20 m/s) motion to do work.

⑤ Rodless cylinder: A general term for cylinders without a piston rod. There are two main categories: magnetic cylinders and cable cylinders.

A cylinder that reciprocates is called a swing cylinder. A vane divides the inner cavity into two parts. Air is supplied alternately to the two chambers, causing the output shaft to swing. The swing angle is less than 280°. In addition, there are rotary cylinders, pneumatic-hydraulic damping cylinders, and stepping cylinders, etc.
