General information
Air springs, also known as pneumatic rubber bellows, are flexible components that utilize compressed air to provide cushioning and vibration isolation. These components are versatile and can be employed in various applications, such as in vehicles and industrial machinery, to absorb shock and reduce noise and vibration.
TEVEMA provides a comprehensive range of air springs, including Single Convoluted Air Springs, Double Convoluted Air Springs, and Triple Convoluted Air Springs. Additionally, we offer Reinforced Rubber Springs in both standard and reinforced variants. Each type is designed to meet specific requirements and applications, ensuring optimal performance in diverse settings.
Our air springs are constructed from high-quality materials to ensure durability and performance. These materials include:
- Natural Rubber (NR/SBR): Known for its excellent universal properties and high dynamic capability.
- Chlorobutyl (CIIR): Offers outstanding resistance to acids.
- Nitrile (NBR): Provides excellent resistance to oils, fuels, ozone, and outdoor conditions.
- Ethylene Propylene Diene Monomer (EPDM): Notable for its high resistance to heat, ozone, and outdoor conditions.
- Chloroprene (CR): Excellent weathering resistance and moderate oil resistance. The metallic components of our air springs are available in electro-galvanized steel for standard applications and stainless steel (AISI-304 and AISI-316L) for environments requiring high corrosion resistance and durability.
TEVEMA air springs function by using compressed air to create an internal force that provides cushioning and vibration isolation. When air is pumped into the air spring, it inflates, and the internal pressure supports the load and absorbs shocks. This makes air springs highly effective in applications where smooth and controlled movement or vibration isolation is crucial.
