Air Springs

ITT air springs are air-tight and sturdy pneumatic actuators for demanding industrial applications.

Air springs are highly durable, precisely engineered and cost-effective for use in a wide variety of actuation and vibration isolation applications. With time-tested designs, fabric-reinforced Neoprene or Natural Robber flex member construction and corrosion-protected end retainers, air springs provide superior quality and performance. 

As an actuator, air springs provide linear or angular motion. These air springs offer a favorable stroke-to-compressed-height ratio when compared to air cylinders, and can accept a wide variety of actuation media such as air, water, nitrogen or anti-freeze.

As an isolator, air springs are effective in reducing the harmful effects of vibration. They can simultaneously isolate vibration and regulate load height, as well as allow for consistent vibration under varying loads.

ITT offers a variety of air spring types to meet your actuation or isolation needs. The Single, Double and Triple Convolute Bellows, Rolling Lobe and Sleeve Types are available in a wide range of sizes, with the End Retainer Style Required for your installation.

Application Examples:

  • Material Handling Industry
  • Lumber Industry
  • Aluminum Can Recycling
  • Container Manufacturers
  • Paper Industry
  • Press Manufacturing
  • Vibrating Equipment & Conveyors

Air Springs for Vibration Isolation

In addition to actuation, many of our air springs can also be utilized as isolators with load bearing capacities ranging from 0.5 kN (112 lbs.) to over 350 kN (78 kip), A number of unique product features make air springs an ideal solution for many different challenging vibration isolation isolation applications.

Product Features

  • Constant Operating Height
    • Our Air Springs are pressurized to maintain a set height, regardless of the load. There is no static spring deflection as with other spring elements.  A user friendly, automatic control system guarantees a constant operating height even under varying loads.
  • Lateral Stability
    • Depending on the type of air spring used, their lateral stiffness can reach up to a 100% of the vertical stiffness.
  • Low Frequency, Load-Independent Vibration Isolation
    • Air Springs enable a very low resonant frequency from approximately 1 Hz to 4 Hz. Here, the resonant frequency is virtually independent of the load-bearing capacity. The excellent insulating effect remains virtually constant even under changing loads.
  • Compact Component Height
    • Our air springs offer a compact component height. There is no static spring deflection.
