Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019, specializes in high-performance bridge components. Our Rubber Bearing for Bridge Expansion Joints Accommodating 50mm Movement is engineered to provide reliable support and accommodate thermal expansion, contraction, and structural movements in bridges. With a factory spanning 1,000–3,000 square meters and a skilled team of 101–200 employees, we deliver products that meet global standards. This bearing is a cost-effective solution for bridges requiring precise 50mm displacement control, ensuring long service life and minimal maintenance.
Our rubber bearings are produced using premium natural rubber or neoprene compounds, reinforced with internal steel plates for enhanced load-bearing capacity. They are designed to absorb vibrations, reduce noise, and protect bridge structures from seismic forces. Whether used in highway bridges, railway overpasses, or pedestrian walkways, this bearing offers exceptional durability and performance.
Key Features & Technical Specifications
- Precise 50mm Movement Capacity: Accommodates thermal expansion and contraction up to 50mm without compromising structural integrity.
- High Load Bearing: Customizable load capacity up to 5000 kN, suitable for heavy traffic bridges.
- Excellent Elasticity: Returns to original shape after compression, ensuring consistent performance.
- Weather & Ozone Resistance: Neoprene option offers superior resistance to UV, ozone, and extreme temperatures.
- Easy Installation: Designed for simple placement between girder and abutment; no special tools required.
- Low Maintenance: No moving parts, eliminating lubrication and regular inspection needs.
- Seismic Damping: Absorbs and dissipates energy from earthquakes, reducing stress on bridge structures.
