Air Bellows for Vibration Isolation in Industrial Applications

Air springs, or air bellows, are essential components in a wide range of industrial applications that require efficient vibration isolation and enhanced stability. At Tevema, we provide high-quality air bellows to address vibration challenges faced by machinery and equipment in various industries. By reducing excessive vibrations, we can help prolong the life of your equipment, enhance performance, and create a more reliable working environment.

The Role of Air Bellows in Industrial Vibration Isolation

Air bellows are widely used for vibration isolation in industrial environments. Unlike traditional coil springs, air bellows offer the unique advantage of adjustable stiffness and load-carrying capacity through the regulation of internal air pressure. This versatility is invaluable in scenarios where dynamic load changes and precision control are required.

By isolating vibrations, air bellows significantly reduce wear and tear on machinery, improve stability, and create a quieter and safer workplace. Additionally, the capability to modify internal pressure makes air bellows ideal for applications involving uneven loads or varying equipment positions.

Key Advantages of Tevema Air Bellows for Industrial Use

  • Superior Isolation Efficiency: Tevema air bellows provide superior isolation efficiency with natural frequencies as low as 1 Hz. This allows equipment to operate with minimal vibrations, resulting in a more stable and efficient process. Achieving similar isolation capabilities with a conventional coil spring would require approximately 9 inches of real deflection—a nearly impossible feat in confined industrial spaces.
  • Adjustable Load Capacity: Through internal air pressure adjustments, the load-carrying capacity of Tevema air bellows can be easily tailored to fit the specific requirements of any machinery. This adjustable height feature is key to maintaining consistent isolation efficiency even in applications with changing loads.
  • Maintenance-Free Operation: Unlike traditional mechanical isolators, air bellows do not require ongoing maintenance or lubrication. This makes them particularly suitable for applications where dirt, grit, or adverse environmental conditions would compromise the efficiency of traditional solutions.
  • Compact Installation Height: One of the major advantages of Tevema air bellows is their compact starting height. The bellows are engineered to operate effectively even at low installed heights, reducing space requirements and simplifying the integration into machinery with tight spatial constraints.

Common Applications of Air Bellows in Industrial Environments

Tevema air bellows are suited for a variety of vibration isolation applications, including:

  • Industrial Machinery: Air bellows help to stabilize heavy machinery such as CNC machines, presses, and industrial mixers. By isolating these machines from the floor, air bellows reduce transmitted vibrations, improving both machine performance and operator comfort.
  • Platform Leveling: Air bellows are often used in platform leveling systems for load-bearing applications where stability is critical. This allows for smoother operation and helps to maintain a consistent platform height regardless of the load.
  • Precision Equipment: Equipment requiring high precision, such as laser cutters and test benches, benefits significantly from the vibration isolation properties of air bellows. Even minor vibrations can negatively affect output quality, and air bellows provide a simple solution to eliminate these disruptions.

Design and Construction of Tevema Air Bellows

Tevema air bellows are carefully designed with a multi-layer rubber and fabric construction to handle extreme operational conditions. Each bellows unit is composed of multiple plies of reinforced rubber with an internal air column providing the isolation force. The end plates are made of either steel or aluminum, ensuring robust connections to mounting structures.

  • Flexible Media Use: While the standard medium used in air bellows is compressed air, our bellows can also function with nitrogen, water (with anti-corrosive considerations), or oil, depending on the specific requirements of the application. The flexibility to utilize different media makes Tevema air bellows adaptable to various environments and industry needs.
  • Temperature and Pressure Handling: Our air bellows can be designed to handle a wide range of temperatures and pressures, from -40°C to +115°C depending on the elastomer used. For high-strength applications, a four-ply construction is available, which allows for a higher pressure capacity, up to 12 bar. This increased capability makes them ideal for demanding industrial conditions.

Key Considerations for Installation and Maintenance

When installing air bellows for vibration isolation, certain key factors must be considered to achieve optimum performance:

  • Proper Alignment: Ensure that the air bellows are aligned correctly to avoid excessive stress on the mounting brackets and bellows themselves. Improper alignment can lead to uneven force distribution, decreasing the lifespan of the system.
  • Load Distribution: The support area of the air bellow should be optimized to ensure even load distribution. Tevema recommends utilizing at least 65% of the support area to prevent premature wear of the rubber bellows.
  • Flexible Stops: For applications involving horizontal movement, such as vibration isolation, it is essential to design flexible stops. These stops should be constructed to allow motion in all directions to maximize isolation efficiency.
