12" x 3 Triple Convoluted Suspension Air Spring Bellow W01-R58-4062 Firestone Air Isolator

GUOMAT 3B12X3T is a heavy-duty triple convoluted rubber air spring designed as a direct replacement for Firestone W01-R58-4062 air spring bellows. Manufactured from premium natural rubber, high-strength reinforced cord fabric, and durable steel components, this air spring provides exceptional load-bearing capacity, vibration isolation, and shock absorption for industrial equipment and suspension systems.

The triple convoluted design offers a greater working stroke and higher vertical travel than single or double convoluted air springs, making it an ideal choice for applications requiring increased flexibility, stable load support, and excellent vibration control. The air spring automatically adjusts to varying loads while maintaining consistent operating height, helping improve equipment performance and reduce mechanical stress.
