When it comes to air bellows in suspension systems, safety is paramount. At Tevema, we prioritize ensuring that our products not only perform optimally but also adhere to the highest safety standards. In this article, we will delve into the common safety concerns associated with air bellows and how to mitigate them effectively.
Overpressure Risks
One of the primary safety concerns with air bellows is the risk of overpressure. Air bellows are designed to operate within specific pressure limits. Exceeding these limits can lead to catastrophic failure. At Tevema, we ensure that our air bellows are tested rigorously to withstand pressures up to 8 bar for standard constructions and up to 12 bar for high-strength constructions.
Causes of Overpressure
Overpressure can occur due to several reasons, including incorrect installation, malfunctioning pressure regulators, or unexpected surges in the system. It is crucial to use pressure relief valves and regular monitoring to prevent overpressure situations.
Preventive Measures
To mitigate overpressure risks, we recommend installing pressure gauges and relief valves. Regular maintenance and inspections are also essential to ensure that the system operates within safe pressure limits. Training personnel on the correct handling and operation of air bellows can further reduce the risk of overpressure.

Material Fatigue and Wear
Material fatigue and wear are inevitable over time, especially in demanding applications. Regular inspections and maintenance are crucial to identify signs of wear early. Tevema uses high-quality materials such as electro-galvanized steel and various elastomers to enhance durability and resistance to environmental factors.
Identifying Material Fatigue
Signs of material fatigue include cracks, deformations, and changes in the physical properties of the air bellows. Regular visual inspections and non-destructive testing methods can help in early detection of material fatigue.
Enhancing Durability
At Tevema, we use advanced manufacturing techniques and high-quality materials to enhance the durability of our air bellows. By selecting the appropriate elastomer and metal components, we ensure that our products can withstand harsh operating conditions and have a longer service life.
Environmental Factors
Environmental conditions such as extreme temperatures, exposure to chemicals, and UV radiation can affect the performance of air bellows. Tevema offers air bellows made from different elastomers like Natural Rubber (NR/SBR), Chlorobutyl (CIIR), and Nitrile (NBR) to suit various environmental conditions.
Temperature Extremes
Air bellows can be affected by both high and low temperatures. High temperatures can cause the rubber to degrade, while low temperatures can make it brittle. Tevema provides air bellows with different temperature ratings to ensure optimal performance in various environments.
Chemical Exposure
Exposure to chemicals can lead to the degradation of the rubber material. Tevema offers air bellows made from chemical-resistant elastomers such as Chlorobutyl and Nitrile to ensure durability in chemically aggressive environments.
Installation and Alignment
Improper installation and misalignment can lead to premature failure of air bellows. It is essential to follow the manufacturer’s guidelines for installation. Tevema provides detailed instructions and support to ensure correct installation and alignment.
Common Installation Errors
Common installation errors include incorrect mounting, improper tightening of fittings, and misalignment of the air bellows. These errors can lead to leaks, reduced performance, and premature failure.
Correct Installation Practices
To ensure proper installation, follow the guidelines provided by Tevema. Use the correct tools and techniques, and ensure that the air bellows are aligned correctly. Regular training and refresher courses for installation personnel can also help in maintaining high installation standards.
Vibration and Noise
Air bellows are often used for their excellent vibration isolation properties. However, improper use can lead to increased vibration and noise. Tevema air bellows are designed to absorb more than 99% of unwanted vibrations, ensuring a quieter and smoother operation.
Causes of Increased Vibration
Increased vibration can be caused by improper installation, wear and tear, or operating the air bellows outside their designed parameters. Regular inspections and maintenance can help in identifying and rectifying these issues.
Noise Reduction Techniques
To reduce noise, ensure that the air bellows are installed correctly and are operating within their designed parameters. Tevema air bellows are designed to minimize noise by absorbing vibrations effectively. Using additional noise-dampening materials can further enhance noise reduction.
Maintenance and Inspection
Regular maintenance and inspection are vital to ensure the longevity and safety of air bellows. Tevema recommends periodic checks for signs of wear, pressure testing, and ensuring that the air bellows are free from contaminants.
Maintenance Schedule
A regular maintenance schedule should include visual inspections, pressure testing, and cleaning of the air bellows. Tevema provides detailed maintenance guidelines to help you keep your air bellows in optimal condition.
Inspection Techniques
Use both visual and non-destructive testing methods to inspect the air bellows. Look for signs of wear, cracks, and deformations. Regular inspections can help in early detection of potential issues, preventing costly repairs and downtime.
