Hengshui Ruibin New Materials LLC, a professional manufacturer based in Hengshui, Hebei, China, presents our premium Laminated Rubber Bearing 10mm Thickness Inner Diameter 100mm for Bridges. Since our establishment in 2019, we have dedicated ourselves to producing high-quality bridge bearings that ensure structural stability and longevity. With a factory spanning 1,000-3,000 square meters and a team of 101-200 skilled employees, we leverage advanced manufacturing techniques to deliver products that meet the rigorous demands of bridge construction worldwide. Our annual export value of US$2.5 Million - US$5 Million reflects the trust placed in us by markets across North America, South America, Europe, Asia, Africa, and Oceania. This bearing is designed to absorb vertical loads and accommodate horizontal movements, providing essential support for bridge decks while minimizing stress on the substructure.
Our laminated rubber bearing consists of alternating layers of high-quality elastomer and steel reinforcing plates, vulcanized together to form a durable, flexible unit. The 10mm thickness and 100mm inner diameter make it suitable for medium-sized bridge applications where precise load distribution and movement accommodation are required. The rubber compound is resistant to ozone, weathering, and aging, ensuring decades of reliable performance even in harsh environments.

Product Features and Benefits
- Superior Load Distribution: The steel laminates evenly distribute vertical loads across the bearing, preventing concentrated stress on the bridge deck and substructure.
- Excellent Flexibility: The rubber layers allow for horizontal and rotational movements caused by thermal expansion, traffic loads, and seismic activity, reducing structural damage.
- Durable Construction: High-quality natural rubber or neoprene resists cracking, ozone attack, and UV degradation, ensuring a service life of over 50 years under normal conditions.
- Corrosion Resistance: The steel plates are fully encapsulated in rubber, protecting them from moisture and corrosive elements, making the bearing suitable for coastal and humid environments.
- Easy Installation: The bearing is lightweight and pre-formed, requiring minimal on-site preparation. It can be installed directly between the bridge girder and pier cap.
- Customizable Dimensions: We offer a wide range of outer diameters, thicknesses, and inner diameters to meet specific project requirements. Contact us for non-standard sizes.
- Low Maintenance: Once installed, the bearing requires no routine lubrication or adjustment, saving long-term operational costs.
- Seismic Performance: The bearing’s flexibility allows it to dissipate energy during earthquakes, providing an additional layer of safety for the bridge structure.
This laminated rubber bearing is manufactured in accordance with international standards such as ASTM D4014 and GB/T 17955 (China national standard), ensuring consistent quality and performance. Each bearing is tested for compressive stiffness, shear modulus, and bond integrity before shipment. Our quality control team uses advanced testing equipment to guarantee that every product meets the specified tolerances.

Frequently Asked Questions (FAQ)
-
Q: What is the typical service life of these bearings?
A: Under normal conditions, our laminated rubber bearings can last over 50 years. The rubber compound is formulated to resist aging, ozone, and UV radiation, and the steel plates are fully encapsulated to prevent corrosion. -
Q: Can you provide bearings with different inner diameters?
A: Yes, we can customize the inner diameter, outer diameter, and thickness according to your project specifications. Please provide your design requirements, and we will manufacture accordingly. -
Q: How do I determine the correct bearing size for my bridge?
A: The bearing size depends on factors such as the vertical load, horizontal movement, rotation angle, and bridge geometry. Our engineering team can assist you in selecting the appropriate bearing based on your structural calculations. -
Q: Are these bearings suitable for seismic zones?
A: Yes, they are designed to accommodate horizontal movements and absorb energy during earthquakes. The flexible rubber layers help dissipate seismic forces, reducing the risk of structural failure. -
Q: What certifications do your products have?
A: Our products comply with international standards like ASTM D4014 and GB/T 17955. We also have internal quality certifications. Specific third-party certifications can be obtained upon request. -
Q: What is the lead time for an order?
A: For standard sizes, the lead time is typically 15-20 days after order confirmation. Custom orders may require 25-35 days, depending on the complexity and quantity. -
Q: Do you offer samples for testing?
A: Yes, we can provide samples for evaluation. Please contact us to discuss sample costs and shipping arrangements. -
Q: How should these bearings be stored before installation?
A: Bearings should be stored in a cool, dry place away from direct sunlight, ozone sources (such as motors), and chemicals. They should be kept flat and not stacked to avoid deformation.
