ARO pneumatic cylinders are available in composite, round line repairable or disposable, and NFPA square interchangeable models. Silverair, Economair, and Provenair are our most popular lines.

Our cylinders range from small bore, repairable double-acting cylinders and medium bore, disposable single-acting cylinders for light duty applications to NFPA interchangeable square head cylinders for rugged use. We offer a variety of bore sizes, stroke lengths and mounting styles to meet a wide range of application requirements. Customize your air cylinder with optional cushions, magnetic pistons, double rod ends, oversized rods or rotated ports.

Many of our air cylinder models are available prelubed, so they're suitable for operations without externally applied lubrication. With a stainless steel or aluminum cylinder body, ARO models are designed to be cost-effective and corrosion resistant.

We also offer a full line of cylinder accessories, including mounts, rod end accessories, alignment couples, cylinder-mounted electrical switches, flow control valves, volume chambers and repair kits.


How to Specify Your Pneumatic Cylinder

Several factors must be considered when selecting the right air cylinder for your application.

  • Proper bore size
  • Cylinder air consumption
  • Rod diameter
  • Piston rod style
  • Cylinder cushions
  • Packing shape and material

See pages 5 - 8 in our Pneumatic Cylinder Catalog for details on calculating bore size, air consumption and rod diameter.

ARO Product Warranty: A Confidence You Can Share

ARO pneumatic cylinders are backed by our famous 5-year warranty, as a measure of the confidence we place in the quality of these products.

Ingersoll Rand/ARO warrants to the original use purchaser of Ingersoll Rand/ARO manufactured cylinders that Ingersoll Rand/ARO will repair or replace, free of charges, including return shipping costs within the Continental United States of America, any such product which under normal use and service proves defective in material or workmanship, as determined by Ingersoll Rand/ARO Inspection, within five years from date of shipment from Ingersoll Rand/ARO, provided the claimed defective product, or part thereof, is promptly returned to the Ingersoll Rand/ARO factory or Ingersoll Rand/ARO authorized warranty repair center with transportation prepaid.

This warranty does not cover failure of parts or components due to normal wear or damage, which in the judgment of Ingersoll Rand/ARO, arises from misuse, abrasion, corrosion, negligence, accident, substitution of non-Ingersoll Rand/ARO parts, faulty installation or tampering.

If Ingersoll Rand/ARO Inspection discloses no defect in material or workmanship, repair or replacement and return will be made at customary charges.

Equipment not covered by Ingersoll Rand/ARO warranty: accessories or components of equipment sold by Ingersoll Rand/ARO that are not manufactured by Ingersoll Rand/ARO (such as switches, hoses, gasoline engines, etc.) are subject to the warranty, if any, of their manufacturer. Ingersoll Rand/ARO will provide the purchaser with reasonable assistance in making such claims.

The foregoing warranty supersedes, voids and is in lieu of all or any other warranties, express or implied, and no warranty or merchantability or fitness for particular purpose is intended or made. Ingersoll Rand/ARO’s sole obligation and the original use purchaser’s sole remedy is as stated above and in no event shall Ingersoll Rand/ARO be liable for any special, direct, indirect, incidental, consequential or other damages, or expenses of any nature including, without limitation, loss of profits or production time incurred by the original use purchaser or any other party.
