  • Air fitting: A tapped hole allowing for the spring to be fed from the air compressor
  • Nut/bolt/mount: The method for attaching the air spring to the component. Some air springs incorporate a bolt and air fitting combination device.
  • Bead plate: Crimped metal plate enclosing the spring and allowing attachment. This is typically forged steel, cast zinc alloy or cast aluminum.
  • Bellows: The physical, multi-layer material withholding the compressed gas. Usually made of neoprene or rubber.
  • Girdle: Only found in air springs of convoluted design, separating the bellows chambers.
  • Bumper: An optional layer of padding protecting the piston from damage if the air spring fails.

  • Piston: The component attached to the machinery requiring suspension, which is in turn supported by the enclosed air. The piston housing is typically attached with further hardware.

Types of Air Springs


Outside of custom fabricated air springs, there are three available types of market-ready air springs.



Due to its durability and simplicity, air springs are good for most industrial and commercial applications. Rubber and neoprene are susceptible to dry rot, so dehumidified conditions could shorten the service life of an air spring. Both rubber and neoprene are suitable for use in high/low temperature applications, but have considerably less heat tolerance than metal spring options. While usable up to 65°C, neoprene should not be used below -40°C, and rubber shouldn't be used in sites below -60°C.


  • Crimped, convoluted bellows, which attach the bellow to the bead plate by a permanent crimp in the plate. These provide good vibration isolation and linear/angular actuation, but are not for vehicle suspensions.
  • Sleeve bellows, which attach the bellows to the bead plate by an external clamp. This air spring type provides good vibration isolation, but only linear actuation. They are not typical in suspensions.
  • Rolling lobe bellows, which incorporate a piston at one end of the bellows, rather than a bead plate. This is most commonly found in vehicle suspensions, and is generally not recommended for vibration isolation.
