Dunlop Pneuride Air Bellows Applications
Dunlop Pneuride air bellows are engineered for applications where standard pneumatic actuators lack sufficient power, require excessive space, or face harsh environments demanding constant maintenance. These robust components are widely used across multiple industries:
Industrial Applications: Paper, food processing, textile manufacturing, and building sectors
Automotive Applications: Auxiliary air suspension and air assist kits for motorhomes
Vehicle Upgrades: Heavy trucks, buses, trains, and industrial/agricultural vehicles
The air bellow functions as a single-acting pneumatic actuator constructed from reinforced elastomer material, featuring metal end covers with mounting holes and air inlets. Available in single, double, and triple convolution types, these bellows excel in vibration isolation, effectively reducing transmitted vibration across various equipment types.
When integrated with existing steel suspension systems, Dunlop air bellows deliver enhanced stability, improved ride comfort, reduced body roll, and adjustable leveling capabilities—providing practical benefits for demanding road conditions and heavy load applications.
