Frequently Asked Questions
What is an air spring shock absorber?
An air spring shock absorber is a vibration isolation device that uses compressed air and elastic rubber structures to absorb vibration and reduce transmitted shock. Compared with traditional metal springs, air spring isolators provide lower natural frequency, smoother operation, and better vibration control for industrial equipment and machinery.
They are widely used in generators, HVAC systems, marine engines, pumps, compressors, precision instruments, and heavy industrial equipment.
What are the advantages of air spring shock absorbers?
Air spring shock absorbers offer several advantages:
- Lower vibration transmission
- Better low-frequency isolation
- Higher comfort and stability
- Adjustable load capacity
- Reduced equipment noise
- Longer machinery lifespan
- Improved protection for sensitive equipment
Because the internal compressed air acts as an elastic medium, the vibration isolation effect is much better than ordinary rubber pads or standard spring mounts in many industrial applications.
Why is fatigue life important for air spring isolators?
Fatigue life directly affects the long-term reliability and safety of the vibration isolation system. Industrial machinery often operates continuously under cyclic loading conditions. Poor-quality air springs may crack, leak, or fail prematurely.
The SKC series has a fatigue life of over 1 million cycles and undergoes professional durability testing to ensure stable operation under long-term dynamic loading conditions.
What industries use SKC stamped cover air spring shock absorbers?
The SKC series is widely used in:
- Industrial compressors
- Diesel generators
- HVAC equipment
- Marine machinery
- Pumps and water systems
- Precision instruments
- Printing machinery
- Textile machinery
- Power generation equipment
- Heavy industrial machinery
- Testing equipment
- Automation systems
These industries require stable vibration isolation and reliable long-term performance.
Can the product be customized?
Yes. The SKC series supports extensive customization services based on customer requirements and operating conditions.
Custom options include:
- Rubber hardness
- Rubber thickness
- Oil-resistant rubber
- Seawater-resistant rubber
- High-temperature resistant materials
- Radiation-resistant materials
- Special mounting holes
- Customized dimensions
- Different connection structures
OEM and ODM services are also available.
What media can be used inside the air spring?
The recommended working media include:
- Air
- Nitrogen
- Water
- Other non-corrosive gases or fluids
The working pressure should not exceed 0.7 MPa to ensure safe and stable operation.
How does an air spring reduce vibration?
An air spring reduces vibration by using compressed air as an elastic buffer. When equipment generates vibration, the air chamber compresses and expands to absorb vibration energy.
At the same time, the rubber structure provides damping characteristics that further reduce shock transmission. This combination allows air spring isolators to achieve better low-frequency vibration isolation than many traditional mechanical springs.
What tests are included in the third-party inspection reports?
The third-party Chinese and English reports include:
- Fatigue life testing
- Burst pressure testing
- Low-temperature brittleness testing
- Ozone aging testing
- Hot air aging testing
- Shore hardness testing
- Rubber tensile strength testing
These reports help ensure product quality, durability, and reliability for industrial applications.
