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
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.
