Pneumatic cylinders also called air cylinders are mechanical devices that take compressed air and convert it to mechanical energy. This energy in turn produces linear or rotary motion. Because it can perform this function in a system, the cylinder acts as a pneumatic linear actuator. The most common types of pneumatic cylinders are single acting (pressure on one side) and double acting. Many industries and applications utilize these cylinders in equipment and systems that require mechanical motion.

The advantages of using a pneumatic cylinder system are the ease of connection with hoses or pipes as it produces a good amount of linear energy. It is also economical because air is inexpensive and can be compressed and stored. To select a pneumatic cylinder for an application, you need to carefully consider specifications that include cylinder stroke, operating temperature and pressure range, mounting options, connector size, material, types of style and features.

Some other options to review when searching for pneumatic cylinder distributors include:

1. Prepare a specification sheet with the pneumatic cylinder system requirements you need.

2. Buy industrial pneumatic cylinders from distributors that carry a wide array of products.

3. Get a pneumatic cylinder manufacturer that can provide custom designed products.

Get pneumatic cylinder information online to help you narrow down cylinder choices

If you are designing a pneumatic system, there are many pneumatic air cylinder styles (for example tie-rod design), features and optional components you may be looking at before making a final choice. The best solution is to get good air cylinder information that can assist you in regards to specs, prices and companies that can meet your design requirements.

I recommend: Go to the GlobalSpec and ThomasNet websites and browse through catalog libraries, specifications, technical information, companies’ listings, products and prices. You’ll be able to compare products and prices, select the product that best suits your specifications or find a custom manufacturer for unique applications. Registration is necessary to access GlobalSpec.

Find pneumatic cylinder suppliers that can meet your need for multiple products

You may be looking for pneumatic cylinders in different style, types and materials. Whether you require a single or double acting, tie rod style cylinders or stainless steel pneumatic cylinders, you need suppliers that provide different varieties and carry accessories.

I recommend: Pneumatic Cylinders & Couplers offers NFPA products that include aluminum, steel, stainless steel cylinders suited for various industries and applications. The company also carries accessories/ mounts and special purpose/custom cylinders. Peninsular Cylinder Co. offers NFPA heavy and medium duty cylinder in steel and aluminum. Accessories and cylinder repair services are also available. At AirCylindersDirect.com, you can find a comprehensive line of pneumatic NFPA interchangeable air cylinders as well as accessories. MSC Industrial Supply Co. also carries a good selection of single acting and double acting cylinders.

Locate pneumatic cylinder manufacturers that offer custom options

Standard pneumatic air cylinders may not meet all the requirements of a design. You need companies that can create custom options or provide optional components (cushion, bumper, flow control, etc.) to handle unique problems or extend the life of a cylinder.

I recommend: Go to TRD Manufacturing, Inc. for custom solutions that include cushions, wear bands, adjustable stroke and many more. Bimba Manufacturing provides custom and semi-custom products tailored for specific applications. See examples of the types of solution the company can provide by going to the solution shop.
