TEVEMA’s D and F Series Air Bellows are designed for demanding industrial applications, providing high-quality solutions for vibration isolationmotion control, and load support. These products, available in SingleDouble, and Triple Convolution variants, excel in durability, flexibility, and isolation efficiency. Due to their low natural frequency, they are ideal for isolating vibrations and shocks, while their unique construction allows for lateral alignment compensation and high load capacities.

D Series Air Bellows

The D Series air bellows from TEVEMA are equipped with removable clamp rings and are designed for both isolation and actuation applications. They are made from high-quality rubber with reinforcing fabric layers, ensuring durability and performance in harsh conditions. The D Series can be mounted with standard top and bottom plates and includes air inlet connections for easy installation.

Key Features:

  • Design Flexibility: Removable clamp rings allow for easy integration with industrial equipment.
  • Standard Pressure Rating: Up to 8 bar working pressure, with an optional 12 bar version available in four-layer construction for heavier loads.
  • Material Options: Available in natural rubber (NR/SBR) with optional materials such as Nitrile (NBR) for oil resistance and Chlorobutyl (CIIR) for higher temperature resistance.

F Series Air Bellows

The F Series offers air springs with bead rings, which are detachable for easy installation and maintenance. This series is especially suitable for industrial applications with high loads that require robust isolation and alignment compensation.

Key Features:

  • Bead Ring Design: These air springs are secured with bead rings, ensuring stability under heavy loads.
  • Pressure and Temperature Tolerances: F Series air springs can handle pressures up to 8 bar, with a four-layer construction available for pressures up to 12 bar. Temperature range of -40°C to +115°C, depending on material selection.
  • Customizable End Fittings: Available with various types of fittings, including shrink-fit and bead ring designs for different industrial applications.

Single Convolution Models

Specialized Applications and Materials

Both D and F Series air springs from TEVEMA can be customized for specific environments:

  • Stainless Steel Components (AISI-304/316): Ideal for use in corrosive environments where chemicals or acids are present.
  • Elastomer Options:
    • Natural Rubber (NR/SBR): Excellent for dynamic applications with a temperature range of -40°C to +70°C.
    • Nitrile (NBR): Best for oil resistance and outdoor applications with temperature tolerances of -25°C to +110°C.
    • Chlorobutyl (CIIR): For high-temperature environments, resistant up to +115°C.
