3B-300 Airkraft Rubber Air Spring FT 412-32 DS Contitech Industrial Isolation System

The GUOMAT NO.3B12X3T is a triple-convoluted rubber air spring designed for industrial vibration isolation, shock absorption, lifting, and pneumatic suspension applications. This component serves as a direct replacement for Airkraft 3B-300 and Contitech FT 412-32 DS style air springs.

The flexible rubber bellows provide effective vertical movement and vibration isolation while maintaining a compact installation profile. Compared to conventional mechanical springs, this pneumatic design significantly reduces transmitted vibration, noise, and mechanical impact in industrial equipment.

This industrial air spring is ideal for machinery and systems requiring controlled pneumatic isolation, precise height adjustment, or reliable shock absorption capabilities.

Advantages of Industrial Air Springs

Rubber air springs offer significant advantages over conventional steel springs by providing flexible pneumatic support and adjustable operating characteristics. By modifying internal air pressure, the air spring can be precisely adapted to varying load and operating conditions.

The three-convolution construction delivers excellent flexibility while accommodating substantial vertical movement. This makes the 3B12X3T particularly suitable for applications where vibration reduction, controlled movement, and equipment protection are critical requirements.
