At Hengshui Ruibin New Materials LLC, we specialize in manufacturing high-quality laminated rubber bearings for bridges with robust 10mm steel plate layers and a total displacement capacity of 50mm. As a factory-direct supplier since 2019, we combine advanced production techniques with strict quality control to deliver durable, reliable bridge support solutions that meet the demands of modern infrastructure projects worldwide. Our bearings are engineered to provide superior load distribution, vibration damping, and seismic resistance, making them an ideal choice for highway bridges, railway bridges, and elevated structures.
Our laminated rubber bearings are constructed by alternating layers of high-quality natural rubber and 10mm thick steel plates, vulcanized together to form a compact, resilient unit. This design allows for controlled horizontal displacement (up to 50mm total) while maintaining vertical load-bearing capacity. The steel plates provide dimensional stability and prevent bulging under heavy loads, while the rubber layers absorb vibrations and accommodate thermal expansion and contraction. Each bearing is manufactured to strict tolerances, ensuring consistent performance and long service life.

Benefits for Your Bridge Projects
- Enhanced Seismic Performance: The laminated structure allows the bearing to deform horizontally during earthquakes, reducing the forces transmitted to the bridge piers and superstructure. This improves the overall safety and resilience of the bridge.
- Durable Construction: Using 10mm thick steel plates ensures high stiffness and load-bearing capacity, while the rubber provides excellent fatigue resistance and weather resilience. The vulcanized bond between layers prevents delamination even under repeated stress.
- Easy Installation: Factory-direct supply means consistent dimensions and pre-drilled holes (if required) for simple anchoring. Our bearings are designed to be directly placed between the girder and abutment, requiring minimal site preparation.
- Cost-Effective: By eliminating middlemen, we offer competitive pricing without compromising quality. The long service life (typically 30+ years) reduces maintenance and replacement costs over the project lifecycle.
- Customizable to Your Needs: We can adjust the number of layers, overall height, displacement capacity, and rubber hardness to match specific project requirements. Contact our engineering team for tailor-made solutions.
Our laminated rubber bearings are widely used in road bridges, pedestrian bridges, and railway bridges across various climates and load conditions. They effectively accommodate bridge movements caused by temperature changes, concrete creep, shrinkage, and traffic loads. The 50mm total displacement capacity is suitable for medium-span bridges, while larger displacements can be achieved through custom designs.
Quality Assurance & Factory Control
At our 1,000-3,000 square meter factory in Hengshui, Hebei, we employ a team of 101-200 experienced workers and engineers. Every production batch undergoes rigorous testing including compressive strength, shear modulus, compression set, and adhesion tests. We follow international standards for bridge bearings (such as AASHTO or EN 1337-3) and can provide test reports upon request. Our annual export value of US$2.5-5 million demonstrates our capability to serve global clients with consistent quality.
Frequently Asked Questions
-
Q: What is the typical lifespan of your laminated rubber bearings?
A: Under normal service conditions, our bearings can last over 30 years. The rubber compound is formulated to resist ozone, UV, and aging. -
Q: Can you provide bearings with different displacement capacities?
A: Yes, the 50mm total displacement is a standard option. We can design bearings with displacements from 20mm up to 150mm based on your project requirements. -
Q: Are your bearings suitable for curved bridges?
A: Yes, our bearings accommodate rotational movements as well. We can supply pot bearings or spherical bearings if needed, but for most applications, laminated bearings with proper design work well. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 50 pieces. For custom sizes, please contact us for a quote. -
Q: Do you provide installation guidance?
A: Yes, we offer technical support including installation drawings and on-site guidance (if arranged). We also provide documentation for quality control. -
Q: How do you ensure the steel plates don't corrode?
A: The steel plates are fully encapsulated by rubber during vulcanization, which provides excellent corrosion protection. Exposed surfaces (if any) can be coated with anti-rust paint. -
Q: What are the main markets you serve?
A: Our products are exported to North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, as well as the domestic Chinese market. -
Q: Can you provide samples before mass production?
A: Yes, sample orders are welcome. We charge a nominal fee for samples and shipping, which is refundable upon bulk orders.
