We are Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a factory spanning 1,000–3,000 square meters and a dedicated team of 101–200 employees. Our annual export value reaches US$2.5 million to US$5 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. As a reliable supplier of bridge rubber bearings, we supply Bridge Rubber Bearing with 1 Year Warranty and Mill Test Report for Each Batch, ensuring every product meets rigorous quality standards. Our bearings are designed to provide exceptional load transfer, vibration isolation, and durability for various bridge structures, making them a trusted choice for infrastructure projects worldwide.
Our bridge rubber bearings are manufactured using high-quality natural rubber or neoprene reinforced with internal steel plates. The lamination process ensures uniform load distribution and excellent elastic recovery. Each bearing undergoes strict quality control, and we provide a Mill Test Report for every batch, detailing material composition, hardness, tensile strength, and adhesion properties. This transparency gives you full confidence in the product's performance. The 1-year warranty covers any manufacturing defects, offering peace of mind for your project.
Key Features and Benefits:
- High Load Capacity: Designed to withstand vertical loads from bridge decks, with capacities up to 5000 kN per bearing. Custom sizes and capacities are available upon request.
- Excellent Seismic Performance: The rubber’s elasticity absorbs and dissipates seismic energy, reducing structural damage during earthquakes.
- Durability & Aging Resistance: Made from premium rubber compounds with UV stabilizers and antioxidants, ensuring long service life even in harsh climates.
- Easy Installation: Simple placement between bridge girder and pier; no special tools required. We provide installation guidelines.
- Wide Temperature Range: Suitable for environments from -40°C to +70°C, maintaining flexibility and performance.
- Customizable Dimensions: We can produce bearings in various sizes (length, width, thickness) to match your project specifications.
- Mill Test Report per Batch: Each batch is tested for hardness (Shore A), elongation, compression set, and bond strength. Data is provided with the shipment.
- 1-Year Warranty: Covers defects in material and workmanship. Our responsive after-sales team handles any issues promptly.
