Rubber Bellow (also commonly referred to as rubber bellows or expansion bellows) are flexible, accordion-style rubber components.
The corrugated structure design accommodates movement, provides sealing and isolates external factors within various industrial and mechanical systems.
The unique pleated design of the bellows enables seamless expansion, compression, bending and twisting whilst maintaining structural integrity. Consequently, it has become an indispensable component in applications requiring flexibility and protective functionality.
Core Characteristics
Flexible Structure : The corrugated foldable design permits movement in multiple directions (axial, lateral, angular) to compensate for misalignment thermal expansion or vibration.
Durable Materials : Manufactured from high-performance rubber or rubber-fabric composites such as EPDM , Nitrile (NBR), Neoprene(CR), Silicone (VMQ), or FKM (Viton). Material selection can be customized to meet specific requirements including temperature resistance (-50°C to +200°C) chemical resistance or pressure tolerance.
Dual Protection and Sealing : Effectively blocks dust, water, dirt, chemicals and other contaminants while forming a tight seal to prevent liquid or gas leakage.
Vibration Damping and Noise Reduction : Absorbs mechanical vibrations and minimize noise transmission between connected components, thereby enhancing equipment stability and operational comfort.

Standard: Goods are typically supplied in about 20-25kg/carton.
Standardized Pallets: Goods are stacked on heat-treated (ISPM 15) or plastic pallets, optimized for forklift handling. Rigid Corner Protectors: High-impact cardboard corner guards are applied to the full height of the stack. This prevents the straps from cutting into the rubber and maintains the vertical integrity of the pallet.
