Asco Numatics & Aventics Pneumatic Cylinders

Pneumatic cylinders, sometimes called air cylinders, use compressed air to create reciprocating motion, often up-and-down or back and forth, similar to hydraulic cylinders. They employ a piston, typically a disc or cylinder, along with a rod to direct the force for movement. We offer a wide range of pneumatic cylinders, including compact, ISO standard, NFPA interchangeable, repairable, non-repairable, rotary, rodless, and custom-made units. Our products are easy to install, highly efficient, and come with over 20 years of experience supplying pneumatic cylinders for various projects across all industries.

Frequently Asked Questions

Double-acting air cylinders operate in both directions, using compressed air through two ports for extension and retraction. They offer precise control for applications needing force in both directions. Single-acting air cylinders, on the other hand, work in one direction, using compressed air for extension and an external force (like a spring) for retraction. They are simpler and more cost-effective, best suited for applications requiring force primarily in one direction. Choosing between them depends on specific application requirements and cost considerations.

Yes, pneumatic cylinders can be designed to stop mid-stroke. This is typically achieved through the use of control valves that can control the flow of compressed air to the cylinder. By adjusting the flow rate or shutting off the air supply at a specific point in the stroke, the movement of the piston can be halted at any desired position within the cylinder's range of motion. Additionally, certain advanced pneumatic systems may incorporate sensors or feedback mechanisms to provide precise control over the cylinder's position and enable accurate stopping at a specific point in the stroke.

In the context of pneumatic cylinders, the term "stroke" refers to the maximum linear distance that the piston or rod of the cylinder can travel from one end to the other. It represents the full extension or retraction length of the cylinder.

The strength of a pneumatic cylinder can vary widely depending on its design, size, and the pressure of the compressed air it's utilizing. Pneumatic cylinders come in a wide range of sizes and configurations, from small units with relatively low force outputs to larger cylinders capable of exerting significant force. In specific applications, multiple cylinders can be used in tandem or in combination with mechanical leverage to achieve even greater force.

Pneumatic cylinders use compressed air as a working fluid, making them suitable for applications where lighter forces and higher speeds are required. Hydraulic cylinders, on the other hand, utilize non-compressible hydraulic oil, allowing them to generate significantly higher forces with precise control over speed and force. While pneumatic systems are compact, lightweight, and environmentally friendly, hydraulic systems excel in heavy-duty applications, offering superior power density and force capabilities.
Pneumatic cylinders are used in a wide range of applications, including automated machinery, manufacturing equipment, material handling systems, robotics, packaging machinery, and more.
Some advantages of pneumatic cylinders include their simplicity, fast response time, precise control, suitability for clean environments (since they do not produce oil-based contaminants), and cost-effectiveness.
Factors to consider include the required force, stroke length, operating environment conditions (such as temperature and humidity), available space, and any specific features needed for your application.
Regular maintenance may involve tasks like inspecting seals, lubricating moving parts, checking for air leaks, and replacing worn components. Always refer to the manufacturer's maintenance guidelines.
Yes, many manufacturers offer customisation options for pneumatic cylinders. This may include variations in size, stroke length, mounting options, materials, and other features to meet specific requirements.
Yes, pneumatic cylinders can be used in vertical applications, but it's important to consider factors like load capacity, speed control, and the need for counterbalance mechanisms to ensure safe and efficient operation.
Yes, many manufacturers offer pneumatic cylinders with specialized coatings or materials, such as stainless steel or corrosion-resistant coatings, to withstand harsh and corrosive environments. This makes them suitable for applications in industries like chemical processing and offshore drilling.

FAQ

Pneumatic Cylinder Specifications

Pneumatic cylinders are occasionally known as air cylinders. These mechanical devices harness the power of compressed air, in order to produce a force in a reciprocating motion, usually up-and-down, or back and forth. They are similar to hydraulic cylinders, as they force a component to move in a specific direction. Usually, the component, a piston, is a disc or cylinder, and a rod transfers the force to move the object.

For some types of work, it is preferable to use a pneumatic cylinder as they are quieter than other types of valves, cleaner and require less space. This type of cylinders is cleaner because they use air rather than a fluid – meaning there is less likely to be a leakage which could contaminate the area. This makes pneumatic cylinders ideal for use in areas where cleanliness is a priority.

Types of Pneumatic Cylinder

Pneumatic cylinders vary in terms of their size and appearance, but there are three main types available on the market. 

Single acting cylinder. This type uses the pressure from compressed air to create a force in one direction – usually outwards, and a spring to return the force to the home direction. The cylinder usually has an extension to compromise for the space that the spring requires.

Double acting cylinder. A double acting cylinder uses the force of air to move in two different strokes – extend and retract. This type of cylinder has two ports to let air in – one for instroke and one for outstroke.

Rodless band cylinder. A rodless band cylinder offers a high level of load control as it has no piston rod. It uses a magnet or mechanical coupling to transmit force to the rest of the cylinder. The cylinder has two flexible metal bands – one is used to stop air escaping, whilst the other is designed to protect the slot and the inner band.

Design of Pneumatic Cylinders

Depending on what the pneumatic cylinder is required for, there are various designs available. Materials used for these cylinders vary between aluminium, steel, nickel plated brass and stainless steel. The type of material selected depends on the temperature, humidity and level of loads that the cylinder is required for.

Tie rod cylinder. This is the most common type and it is usually deemed to be the safest.

Flanged-type cylinder. Fixed flanges are fitted to the cylinder – this is more common in hydraulic cylinders rather than pneumatic cylinders.

Threaded end cylinder. The ends of this type of cylinder are screwed onto the body.

Asco Numatics pneumatic cylinders are available for sizes ranging from 20MM to 200MM, however custom options are available on request.
