Asco Numatics & Aventics Pneumatic Cylinders

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. We have a range of pneumatic cylinders available for various tasks. You can choose from different compact, ISO standard, NFPA interchangeable, repairable, non-repairable, rotary, rodless and speciality made to order units. Our products are easy to install and highly efficient, and we have over 20 years experience of supplying pneumatic cylinders for a variety of projects across all industries.

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.

Pneumatic Cylinder Specifications

Bore Size Range: 20MM – 200MM
Body Materials: Aluminium, Stainless Steel (More on request)
Port Size Range: 1/8” – 1 1/4” & M5/M7
Applications: Bottling, Press Printing/Stamping, Biofuels, Suspension, Heating, Life Sciences
Applications: Tyre Manufacturing, Refining, Commercial Laundry, Combustion, Automotive

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.
