How to find the right Mechanical Air Springs AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Mechanical Air Springs
- Design type
- Convoluted (bellows) styles suit short-stroke actuation and isolation in a compact height; rolling-lobe (sleeve) styles suit longer stroke and softer isolation The construction sets the usable stroke, the force curve and the isolation performance.
- Height range
- Operate only between the manufacturer's published minimum and maximum heights, and use a bump stop or external stop at the limits Overextension tears the bead area, and overcompression damages the rubber member.
- Force at design height and pressure
- Size from the manufacturer's load-at-pressure chart at your working height, and stay within the rated maximum pressure Force changes strongly with height for a given pressure, so a single headline force number is misleading.
- Mounting and air port
- Match the bead plate bolt pattern, the stud thread and the air inlet thread exactly to your fixture These details vary even between springs of the same size and are the usual reason a replacement does not fit.
- Isolation natural frequency
- For vibration isolation, choose a spring whose natural frequency at your load is well below the disturbing frequency An isolator tuned near the forcing frequency amplifies vibration instead of reducing it.
Brands that matter
- Firestone Industrial Products: Airstroke actuator and Airmount isolator lines are an industry reference with detailed design-height charts.
- ContiTech: Continental's industrial air spring range, including the former Goodyear industrial air spring line.
What to avoid
- Automotive suspension air bags used as industrial actuators without load and height data
- Unbranded air springs with no published height range or pressure rating
- Running the spring without stops at either end of the stroke
Questions
Is an air spring the same as a gas spring?
No. An air spring is a flexible rubber bellows fed by external compressed air with adjustable force; a gas spring is a sealed cylinder with a fixed nitrogen charge.
