What is a pneumatic cylinder?
A pneumatic cylinder is a mechanical device that generates force through compressed air. It usually consists of a piston, a piston rod, and a cylinder barrel. When compressed air enters one side of the cylinder barrel, the internal pressure increases, pushing the piston in a specific direction, while the piston rod transmits the generated force to the target object.
Since the working fluid used by Pneumatic Cylinders is compressed air, it will not pollute the environment when it leaks, making it ideal for places with high cleanliness requirements. In addition, Pneumatic Cylinders operate quietly and do not require large tanks to store the working fluid.
Pneumatic Cylinders are widely used in mechanical automation and industrial processes to provide force and motion for operations such as clamping, pushing out, blocking, and lifting. In manufacturing environments, Pneumatic Cylinders are often used to move objects from one device to another. Pneumatic Cylinders are also used to control the operation of valves in piping systems.
Components of Pneumatic Cylinders
The main components of a cylinder include:
Barrel: Contains and protects the internal components. The ends are sealed by front and rear covers, which usually have ports for air to enter and exit.
Piston: A movable diaphragm inside the cylinder that is pushed by compressed air to reciprocate in a straight line.
Piston rod: Connects and drives mechanical components, transmitting the force of the piston movement to the target object.
Buffer: Reduces the speed of the piston assembly when it reaches the end cover, reducing shock and vibration.
Seal: Ensures airtightness between the piston and the barrel and between the piston rod.
Guide ring: Prevents direct contact between metals during sliding movement and absorbs radial forces.
Sensor: Used to detect the position of the piston. Common types include reed switches and Hall effect sensors.
Tie rod: used to fix the end cap to the cylinder barrel and provide additional structural strength to the cylinder.
BLCH offers a wide range of high-quality Pneumatic Cylinders for a wide range of industrial applications.
Types of Pneumatic Cylinders
Double-acting Pneumatic Cylinders: compressed air can enter both sides of the piston to achieve extension and retraction movements, suitable for applications requiring high speed and high force.
Single-acting Pneumatic Cylinders: only one air chamber is used to push the piston, and retraction is achieved by built-in springs or external forces. The design is simple and cost-effective.
Rodless Pneumatic Cylinders: connected to the piston through a carrier, no piston rod is required, suitable for scenes with limited space.
Special types of Pneumatic Cylinders: including telescopic Pneumatic Cylinders, tandem Pneumatic Cylinders and rotary Pneumatic Cylinders, which are suitable for ultra-long strokes, high force output and rotary motion respectively.
BLCH offers various types of Pneumatic Cylinders to meet different application requirements, and its high performance and reliability are deeply trusted by customers.
How to install a pneumatic cylinder?
The mounting method of a cylinder can significantly affect its performance and reliability, and can be divided into the following categories:
Centerline mounting: includes tie rod Pneumatic Cylinders and flange Pneumatic Cylinders, providing symmetrical force transmission.
Side mounting: such as side-mounted Pneumatic Cylinders and foot-mounted Pneumatic Cylinders, suitable for specific space constraints, but may be affected by torque.
Pivot mounting: allows the cylinder to be adjusted in a single plane, suitable for applications with non-linear load paths.
ISO standards for Pneumatic Cylinders
ISO standards for Pneumatic Cylinders ensure compatibility and interchangeability of products, including:
ISO 15552: defines cylinder sizes for a maximum pressure of 10 bar and a bore diameter of 32-320 mm.
ISO 6432: for compact Pneumatic Cylinders, applicable to bore diameters of 8-25 mm.
ISO 21287: specifies the dimensions and performance of compact Pneumatic Cylinders with a bore diameter range of 20-100 mm.
All BLCH Pneumatic Cylinders strictly follow international ISO standards, ensuring that customers can quickly find products that suit their needs.
Conclusion
