Critical Safety Guidelines for AIRSUSTECH Air Springs​​


​​1. Torsion Prevention​​

Super Cushion air springs must never be subjected to twisting forces during installation or operation. Torsional stress compromises structural integrity and may lead to catastrophic failure of the assembly.


​​2. Height Limitations​​

Always observe the manufacturer-specified maximum extended height. Exceeding this limit risks permanent deformation of internal components and voids product warranties. For optimal service life, restrict travel within the designated actuator height range.


​​3. Pressure Restrictions​​

  • Absolute Maximum Inflation Pressure​​: 100 psi (6.9 bar)
  • Peak Internal Pressure Limit​​: 200 psi (13.8 bar) in any operating condition.
  • These thresholds represent critical safety boundaries that must never be surpassed.

​​4. Compression Safety​​

Never compress the air spring below its minimum specified height without proper bump stops installed. Bottoming out the assembly causes irreversible damage to internal components.


​​5. Minimum Pressure Requirements​​

Maintain at least 10 psi (0.7 bar) residual pressure in rolling lobe/sleeve-type springs during compression attempts. This ensures proper flex member articulation and prevents destructive folding.


​​6. Fluid Compatibility​​

Hydraulic oil actuation requires explicit approval from Goodyear Tire & Rubber Company. Unapproved fluids may degrade elastomers and void product warranties. Always verify compatibility before implementation.
