Customized Reversible Style Truck Air Spring With High Strength Rubber Compound Material

EVEN (Qingdao Guoxiang Yiwen Rubber Technology Co., Ltd.) supplies high-performance reversible style air springs for truck chassis suspension systems. Engineered with specialty rubber and the world-first "Liquid Gold" material, our reversible sleeve air springs provide reliable support and outstanding durability for heavy-duty trucks, tractors and semi-trailers in highway logistics and engineering transport.

• Structural topology optimization - optimized material distribution reduces stress concentration; modular segmentation with reinforced end sections and a flexible central buffer achieves the ideal balance of lightweight and strength.
• Specialty rubber + "Liquid Gold" material - the world-first liquid-phase mixing compound delivers ultra-long fatigue durability and wear resistance.
• 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 air spring 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 (inflation pressure 0.7 MPa, amplitude ±50 mm, frequency 2.5 Hz, per GB/T13061).

• Truck chassis suspension systems (OEM and aftermarket).
• Widely matched with leading Chinese truck brands including Shaanxi Automobile (Delong X3000/X5000), Sinotruk (SITRAK C7H/T7H) and BPW axle applications.
• Semi-trailer and hazardous chemical transport vehicle applications (e.g., BPW30K).
• Highway logistics, urban transit and off-road operating scenarios.

• Fatigue life of up to 18.17 million cycles, reaching an internationally leading level.
• Fatigue cycles exceed the national standard (GB/T13061) by more than 2 times under compact-size and heavy-load conditions.
• Full model interchangeability with major OE references (ContiTech / Firestone cross-reference available).
• Backed by the National Rubber & Tire Engineering Technology Research Center (Guoxiang Industry Chain), with 3,500+ patents and IATF 16949 certification.
• Customized development and collaborative design available according to customer requirements.
