Pyramidic Type Air Suspension Bellows Replacement For Passenger Vehicle

EVEN (Qingdao Guoxiang Yiwen Rubber Technology Co., Ltd.) supplies high-performance pyramidic type air spring bellows for passenger vehicle air suspension systems. The pyramidic (tapered) profile is engineered to deliver progressive spring characteristics, providing an optimal balance of ride comfort, load-bearing capacity and torsional resistance for modern passenger cars and new energy vehicles.

• Pyramidic profile design - progressive stiffness curve and optimized material distribution reduce stress concentration, ensuring stable performance under varying load conditions.
• Specialty rubber compound - manufactured with specialty rubber and the world-first "Liquid Gold" (EVEC) liquid-phase mixing material, delivering 4.3 times the extension fatigue performance and 5.8 times the flexural crack resistance of competitor formulations.
• Ultra-strong bonding technology - advanced rubber-to-cord adhesion improves bonding performance by 30%-50% compared with conventional products.
• Advanced manufacturing - produced on a fully automatic winding production line with precise calendering, processing and adhesion control, ensuring consistent quality.
• Full lifecycle traceability - every bellow is traceable from raw material to finished product through the Eco-Rubber Cloud system with MES, WMS and ERP integration.
• Rigorous testing - each product passes 80°C and -40°C vertical durability tests and 1/4 suspension durability tests, with fatigue life exceeding twice the national standard under compact-size and heavy-load conditions.

• Passenger car air suspension systems (OEM and aftermarket).
• New energy vehicles (NEV) and luxury vehicle platforms.
• Compatible with multiple vehicle models - custom development and collaborative design available per customer requirements.

• No.1 market share in passenger car air spring bellows in China.
• Over 9 million units delivered to high-end OEM customers since establishment, including over 6 million units supplied to innovative pioneers and market-leading brands in China's new energy vehicle sector.
• The first Chinese brand to break the international monopoly in passenger car air spring bellows.
• Backed by the National Rubber & Tire Engineering Technology Research Center (Guoxiang Industry Chain), with 3,500+ patents and IATF 16949 certification.
• Experienced engineering team providing customized formulation development, structural design and manufacturing services.
