FS Type Single Bellow Air Sping

FS Type Edge-wrapped plate integrated rubber air spring

Frequently Asked Questions

FS-Type Rubber Air Springs offer a range of benefits that make them highly suitable for industrial vibration isolation and load-bearing applications:

  1. Excellent Vibration Isolation
    The flexible rubber air chamber effectively absorbs and isolates both high- and low-frequency vibrations, reducing noise and protecting sensitive equipment.

  2. Adjustable Load and Height
    Air pressure inside the spring can be adjusted to accommodate different load conditions, making it ideal for dynamic systems such as HVAC units, compressors, and platforms.

  3. Modular Design with Movable Flange
    Each FS-type air spring is equipped with a movable flange, allowing the user to easily assemble it with an additional blind plate using bolts. This design makes installation, removal, and replacement of the rubber airbag extremely convenient—especially useful when only the rubber part is damaged.

  4. Long Service Life
    Made from high-strength, wear-resistant rubber (like neoprene), FS-Type air springs are built for thousands of compression cycles in harsh environments without loss of performance.

  5. Low Maintenance
    Unlike metal springs, FS air springs operate without metal-to-metal contact, requiring no lubrication and minimal maintenance over time.

  6. Compact and Lightweight
    The cylindrical design allows for easy integration into tight or limited spaces, while still delivering high load capacity.

The FS-Type air spring functions by utilizing a rubber airbag that compresses and expands to absorb shocks and vibrations. As a load is applied, the internal air pressure adjusts to match the weight, enabling the air spring to maintain a steady height and efficiently isolate vibrations from external sources. Its design incorporates sealed end plates, eliminating the need for additional components and ensuring easy installation. This construction provides superior vibration dampening and impact absorption, improving comfort and safety. These air springs are ideal for use in various machinery and vehicles, delivering reliable performance in diverse applications.
