Robust Fabric-Reinforced Bellows

Heavy-Duty Composite and Wrapped Bellows for Harsh Industrial Conditions

Engineered for high temperatures, chemicals, and aggressive operating environments, these fabric-reinforced bellows—also known as composite bellows or wrapped bellows—offer excellent dimensional stability and protection. Their structure can be enhanced with internal wire rings or coil springs for added support and longevity. For maintenance ease and retrofits, a zipper is an option. Common applications include industrial machinery, automotive, printing equipment, and ball screw or piston rod protection.
