They feature reinforced multi-ply fabric layers, enhancing durability in extreme settings. Custom diameters range from 80 mm to 950 mm, ensuring adaptability. Each unit undergoes rigorous fatigue testing, exceeding 1 million cycles, verifying longevity. Corrosion-resistant metal components, including stainless steel (AISI 304 & 316L), improve reliability in aggressive environments.
Why Custom Air Bellows Matter in High-Pressure Systems
Industrial systems operating under high pressure require air bellows with reinforced construction, increased resistance to wear, and the ability to maintain precise force control. Standard configurations often fail to meet unique operational demands, making custom solutions a necessity for industries requiring:
- Enhanced vibration isolation for sensitive machinery.
- Optimal stroke length adjustments for dynamic movement.
- Increased structural resilience to withstand fluctuating loads.
- Superior adaptability to various high-pressure media, including compressed air, water, and oil-based environments.
Our air bellows provide axial loads up to 450 kN, allowing safe operation in heavy-duty conditions. With height variations from 50 mm to 400 mm, they integrate into compact installations. Operating temperature ranges from -40°C to +115°C, depending on material selection. Using low-friction elastomers, they maintain efficiency and eliminate performance degradation due to surface wear. Their natural frequency remains stable, preventing excessive vibrations in precision systems.
