A flange type air spring is an industrial air suspension component that uses flange-based mounting plates at one or both ends to securely connect to equipment or machinery. Flanges provide fast, stable, bolt-secured assembly between components, particularly in pressure-related systems and heavy-duty equipment.
In air spring systems, this flange structure ensures tight sealing, stable installation, and reliable force transmission under compressed air conditions.
- Reinforced rubber bellows (air chamber)
- Upper and lower metal flanges
- Bolt holes for mechanical fastening
- Air inlet port for pneumatic control
The flanges are bolted to mounting plates, creating a strong mechanical connection that prevents air leakage and ensures stable operation even under continuous load cycles.
