The performance and durability of heavy-duty suspension systems rely heavily on the components that absorb and isolate vibrations. Air bellows are an integral part of that system, offering unmatched vibration damping and height regulation properties. At Tevema, we understand the demands placed on industrial suspension setups, particularly those involving large, variable loads. Our focus is on supplying robust air bellows that ensure precise performance, high-load stability, and minimal maintenance in heavy machinery and industrial suspensions. Engineered from reinforced rubber compounds, our bellows combine flexibility with structural strength. Whether single, double, or triple convolution designs, each product is tailored to deliver superior vibration isolation, consistent height control, and extended operational life. This makes them particularly effective in environments requiring high durability under fluctuating load conditions. Their ability to maintain uniform movement, absorb lateral misalignment, and resist weathering makes them a superior alternative to mechanical spring systems.
High-performance vibration isolation
Air bellows are specifically developed to isolate machinery from dynamic forces. Using internal air pressure, they absorb shocks and vibrations far more effectively than conventional springs. The result is uniform isolation properties across varying loads and operating heights. This allows us to maintain consistent equipment performance, while significantly extending the lifespan of surrounding components. Our low-frequency isolators can reduce unwanted vibrations by more than 99%, minimizing stress on welded joints and mechanical assemblies. With sizes ranging from small-diameter models to large triple convolution units, our bellows accommodate a wide range of force capacities, up to 380 kN per unit. Their natural frequency remains stable even under shifting load profiles, maintaining optimal isolation throughout the entire load cycle. Each bellow has a tested frequency range from 1.2 Hz to 4.6 Hz, depending on type. Effective vibration damping results from the elasticity of multilayer rubber, reinforced with internal textile plies and corrosion-resistant end closures.
Adjustable height control under load
A key feature of air bellows is the ability to regulate system height with precision. By adjusting internal air pressure, we can guarantee a uniform operating height even under alternating load conditions. This is vital for maintaining balance, load symmetry, and operational consistency in systems exposed to fluctuating weights. We offer both dismountable and sealed bellow designs depending on your mounting preference. The dismountable D-series provides flexibility and reusability, while F-series bellows feature bead ring and crimped end closures for sealed, maintenance-free operation. Design heights range from 60 mm to 375 mm, depending on configuration. Available with standard or high-strength four-ply construction, our bellows support pressures up to 12 bar in enhanced configurations. This allows us to handle more extreme vertical loads without compromising on height stability. Stroke ranges vary from 36 mm to 452 mm, enabling adaptability across low-profile and high-lift systems with dynamic height requirements.
Long-lasting durability in harsh conditions
At Tevema, we prioritize material science and precision bonding in all our air bellows. Using natural rubber (NR/SBR), chlorobutyl (CIIR), nitrile (NBR), EPDM, and chloroprene (CR), we offer bellows that resist abrasion, corrosion, oil, fuel, and ozone. These elastomer compounds allow our bellows to operate in temperatures from -40°C to +115°C, making them suitable for nearly all industrial environments. The steel components are offered in electro-galvanized, aluminum, or AISI-304 stainless steel, enabling long-term use in acidic or chemical-prone environments. Where necessary, AISI-316L is also available on request. This combination of rugged rubber and precision-machined metal delivers a reliable solution for conditions involving moisture, extreme heat, or oil-saturated atmospheres. Our bellows comply with ISO 2230 rubber storage guidelines. Internal textile layers consist of high-strength fibers woven for cyclic fatigue resistance exceeding one million compression cycles under normal conditions.
Compact, flexible actuator solutions
Beyond vibration isolation, air bellows serve as highly efficient pneumatic actuators. Unlike traditional cylinders, our bellows require minimal installation space and offer flexibility for lateral misalignment up to 30 mm. Their compact size makes them perfect for tight industrial layouts where space-saving designs are critical. Each model exhibits uniform stroke behavior due to the natural expansion of rubber membranes under pressure. This avoids the common stick-slip effect found in rigid actuators. Their ability to support angular motion up to 25° makes them versatile in both vertical and tilted configurations. With no friction-based internal movement, energy is transferred directly and smoothly, reducing system fatigue. Available diameters range from 80 mm to 950 mm, covering forces from 0.5 kN to 450 kN. Our actuators can be mounted with threaded holes, blind nuts, or fixed plate assemblies for enhanced structural compatibility and simpler integration into automation lines.
Custom configurations for every requirement
Tevema offers an extensive catalog of air bellows across single, double, and triple convolution configurations. Clients can choose between standard, high-temperature, or stainless steel executions, with optional features such as blind nuts, BSP/NPT air inlets, and socket-head or countersunk bead rings. We tailor the design and connection geometry to match your equipment’s dimensional and performance needs. Each unit comes with detailed specs including diameter, stroke, design height, and natural frequency. For applications requiring high pressure tolerance, we provide four-ply versions capable of withstanding up to 12 bar, delivering superior force output and stroke stability. Bellow response time is also optimized for pneumatic systems with low reaction delay. We support a wide range of industrial systems, ensuring seamless integration and long-term performance. No matter your specifications, we ensure that our air bellows are built for precision, strength, and versatility.
