Air bellows in bespoke machinery for unique industrial tasks offer transformative potential for engineers developing complex mechanical systems. We integrate air bellows into custom industrial machinery to achieve superior vibration isolation, load compensation, and motion control. These components, produced with a variety of elastomer compounds and metallic closures, perform reliably in environments demanding high adaptability. From force transmission to precise leveling, air bellows enable machine customization not achievable with traditional actuators. With diameters ranging from 80 mm to 950 mm and stroke lengths up to 400 mm, they adapt well. Their maximum allowable pressure reaches 8 bar in standard configurations or 12 bar for reinforced versions. This versatility ensures reliable integration into bespoke applications with changing mechanical conditions and design constraints.
High-performance vibration isolation
We engineer our air bellows to provide more than 99% vibration isolation efficiency. In bespoke equipment, this contributes to the longevity of mechanical components and reduces structural noise. As rubber isolators, they maintain a constant natural frequency, even with shifting operating weights, which ensures uniform performance. Our selection includes both single, double, and triple convolution bellows, allowing precise adaptation to each use case. Models achieve natural frequencies as low as 1.2 Hz, suitable for delicate setups. Design heights range from 45 mm to 140 mm depending on configuration. They can absorb energy and vibration from rotating or oscillating parts, preventing harmful resonance. The correct combination of pressure, design height, and diameter ensures peak isolation. Our bellows reduce transmitted forces that damage sensitive components.
Load compensation and motion absorption
In many industrial setups, air bellows serve as flexible load compensators, adjusting automatically to changing weights. Their ability to absorb lateral shifts up to 30 mm reduces wear and protects sensitive parts from stress-induced damage. We leverage four-ply reinforced bellows when high internal pressures are needed, increasing performance up to 12 bar. These are essential in systems requiring strong thrust or precise motion control under variable conditions. Forces range up to 450 kN per unit depending on convolution and design pressure. Bellows can also compensate for angular displacement up to 25°, providing critical support in misaligned systems. Their resistance to environmental factors such as ozone, oil mist, or temperature fluctuations is a key benefit in harsh environments. With materials ranging from natural rubber to nitrile and EPDM, we tailor our solutions to meet chemical resistance or heat endurance needs.
Optimizing custom machinery footprint
Space optimization remains a primary concern in custom-built industrial setups. Our bellows feature a low installation height while still achieving impressive stroke lengths. This allows system architects to design compact layouts without compromising on performance. For small, high-precision systems, we recommend our single convolution models. For larger-scale operations, we deploy multi-convolution variants that increase stroke and force output. Some models reach up to 75 mm stroke, while retaining total heights under 150 mm. By adjusting design height and plate dimensions, we deliver units that meet both physical constraints and performance requirements. Our modular approach simplifies maintenance by allowing quick replacement of worn components. We often incorporate dismountable designs for field-serviceable configurations, reducing downtime and operational costs. These designs support efficient integration into highly tailored systems, regardless of the scale or purpose of the machine.
Material selection and environmental resilience
We select elastomer types according to their dynamic properties, chemical compatibility, and temperature range. Our bellows can operate in extreme environments—from -40°C with natural rubber, up to +115°C using EPDM or chlorobutyl. These materials ensure long-term durability even in chemically aggressive or humid areas. The use of galvanized, stainless steel, or aluminum end plates provides added corrosion resistance where needed. High-strength applications benefit from reinforced fabric plies and steel bead rings vulcanized into the rubber body. We avoid failure from media penetration or fatigue cracking through precision molding and thorough quality checks. Typical burst pressures exceed 24 bar, adding a margin of safety. These manufacturing processes result in consistent wall thickness, optimal pressure resistance, and excellent elastic behavior under cyclic loading.
Maintenance-free operation with long service life
Air bellows operate without sliding seals, which eliminates one of the main failure points of traditional actuators. As a result, they are effectively maintenance-free and reduce total cost of ownership over time. The rubber body resists abrasion and does not suffer from stick-slip effects seen in piston-based systems. Our clients benefit from a consistent response behavior, making the technology suitable for automation tasks. Additionally, the lack of lubrication requirements eliminates contamination risks in cleanroom applications. Many of our installations operate reliably for years without intervention, supporting predictive maintenance cycles. Models feature mounting hole tolerances suitable for M6 to M10 threads. We provide documentation on pressure ranges, natural frequencies, and mounting configurations to aid in accurate planning. Where extra protection is needed, we advise using protective bellows covers and stainless steel variants.
Seamless integration in specialized systems
The adaptability of our bellows supports integration across a wide array of custom machinery. With over 40 standard sizes and numerous threaded mounting options, engineers can match the required load profile and stroke to existing layouts. Our bellows maintain predictable force curves, essential for synchronized multi-actuator systems. We also offer assistance with natural frequency tuning, optimizing setups for resonance-free operation. Bellows can include air inlets ranging from G1/4″ to G3/4″, depending on the size and flow demand. Design variants like socket head, countersunk, or threaded ring closures further expand installation possibilities. Combined with a wide diameter range, from 80 mm to over 950 mm, our solutions suit both compact assemblies and heavy-duty equipment. Our technical team can also help with 3D CAD models and installation guidance for seamless implementation.
Tailored configurations for maximum performance
No two machines are identical, and our air bellows reflect this reality. We offer fully customized configurations in both the D and F series, based on stroke, design pressure, and material demands. Whether a project requires high stroke at low pressure or maximum force in tight quarters, we can provide the optimal solution. Our product selection covers both standard and reinforced bellows, enabling reliable operation in diverse contexts. Maximum stroke per bellow reaches 400 mm in some configurations. We assist in calculating axial force output, checking fatigue limits, and determining the ideal natural frequency for each system. This process ensures the bellows work harmoniously within the broader mechanical framework. By selecting the correct convolution number, plate type, and air inlet position, we help clients achieve machine efficiency and operator safety. We partner with engineers at every phase—from concept to commissioning.
