Extruded air cylinders are pneumatic actuators used to convert compressed air energy into mechanical motion. They are characterized by their construction, where the cylinder body is made from an extruded aluminum profile. This design offers several advantages, including lightweight, durability, and cost-effectiveness. The extruded aluminum body provides a smooth, corrosion-resistant surface, which enhances the cylinder's longevity and performance. The extrusion process allows for precise dimensional control and the integration of mounting features directly into the cylinder body, facilitating easy installation and alignment in various applications. Extruded air cylinders typically consist of a piston, rod, and end caps, with the piston moving within the cylinder bore when air pressure is applied. The movement can be linear or rotary, depending on the cylinder design. These cylinders are available in various configurations, such as single-acting (air pressure moves the piston in one direction, with a spring returning it) or double-acting (air pressure moves the piston in both directions). They are widely used in industrial automation, robotics, and machinery due to their reliability and efficiency. Applications include material handling, packaging, assembly lines, and any process requiring controlled linear motion. The extruded design allows for customization, such as different bore sizes, stroke lengths, and mounting options, to suit specific application needs. Overall, extruded air cylinders are a versatile and essential component in pneumatic systems, offering a balance of performance, durability, and cost-effectiveness.

Extruded air cylinders, also known as pneumatic cylinders, convert compressed air energy into mechanical motion. They consist of a cylindrical tube, typically made from extruded aluminum for strength and lightweight properties, with a piston inside. The cylinder is sealed at both ends with end caps, and the piston is connected to a rod that extends outside the cylinder. When compressed air is introduced into the cylinder through an inlet port, it fills the chamber on one side of the piston. The pressure difference between the two sides of the piston causes it to move, pushing the rod outward. This movement can be linear or rotary, depending on the cylinder design. The force exerted by the piston is proportional to the air pressure and the piston area. To retract the piston, air is introduced into the opposite side of the cylinder through another port, while the air on the initial side is vented out. This reverses the pressure differential, causing the piston to move back to its original position. Extruded air cylinders can be single-acting or double-acting. Single-acting cylinders use air pressure to move the piston in one direction, with a spring or external force returning it. Double-acting cylinders use air pressure for both extension and retraction, providing more control and power. These cylinders are used in various applications, including automation, manufacturing, and robotics, due to their efficiency, reliability, and ease of control. They are favored for their ability to produce smooth, precise movements and their adaptability to different environments and tasks.

Extruded air cylinders are mounted using several methods, each suited to specific applications and requirements. The most common mounting styles include: 1. **Foot Mounting**: This involves attaching the cylinder to a surface using brackets or feet that are bolted to the base of the cylinder. It provides stability and is ideal for applications where the cylinder needs to be fixed in a horizontal position. 2. **Flange Mounting**: Flanges are attached to either the front or rear end of the cylinder. This method is suitable for applications requiring the cylinder to be mounted perpendicular to a surface. Front flange mounting is used when the load is applied in the direction of the piston rod, while rear flange mounting is used when the load is applied in the opposite direction. 3. **Clevis Mounting**: A clevis bracket is used to allow the cylinder to pivot, accommodating angular motion. This is ideal for applications where the cylinder needs to follow a curved path or where alignment changes during operation. 4. **Trunnion Mounting**: Trunnions are pivot points attached to the cylinder body, allowing it to rotate. This mounting style is used in applications where the cylinder needs to pivot around a fixed point, providing flexibility in movement. 5. **Tie Rod Mounting**: Tie rods extend through the entire length of the cylinder, providing additional strength and support. This method is often used in heavy-duty applications where the cylinder is subjected to high loads. 6. **Nose Mounting**: The cylinder is mounted by its nose, which is threaded or has a flange. This is suitable for applications where space is limited, and the cylinder needs to be mounted in a compact area. Each mounting style offers specific advantages and is chosen based on factors such as load direction, space constraints, and the required range of motion.
