As a professional manufacturer based in Hengshui, Hebei, China, Hengshui Ruibin New Materials LLC proudly presents the Steel-Reinforced Neoprene Laminated Elastomeric Bridge Bearing Pad. This product is engineered to provide superior load-bearing capacity, long-term durability, and reliable performance in demanding bridge construction projects. With over 5 years of expertise and a dedicated team of 101-200 employees, we ensure every bearing pad meets stringent quality standards. Our ISO9001-certified production process guarantees consistency and reliability, making our bearing pads a trusted choice for infrastructure projects worldwide.
The Steel-Reinforced Neoprene Laminated Elastomeric Bridge Bearing Pad is designed to accommodate vertical loads, horizontal movements, and rotations in bridge structures. The combination of high-quality neoprene rubber and internal steel reinforcement plates offers exceptional strength and flexibility. This bearing pad effectively absorbs vibrations, reduces noise, and compensates for thermal expansion and contraction, ensuring the structural integrity of bridges over time. It is suitable for a wide range of applications, including highway bridges, railway bridges, and pedestrian overpasses.
Our bearing pads are manufactured using advanced lamination technology, where layers of neoprene are bonded to precisely positioned steel plates. This construction provides uniform load distribution and prevents excessive deformation under heavy loads. The neoprene material offers excellent resistance to weather, ozone, aging, and chemicals, making it ideal for both indoor and outdoor installations. Additionally, the steel reinforcement enhances the pad's ability to withstand high compressive forces without compromising its elastomeric properties.
Key Features & Technical Specifications
- High Load Capacity: Designed to support vertical loads ranging from 100 kN to over 5000 kN, depending on size and configuration.
- Excellent Durability: Neoprene rubber provides excellent resistance to UV radiation, ozone, and extreme temperatures (-40°C to +100°C).
- Steel Reinforcement: Internal steel plates add rigidity and prevent excessive lateral deformation, ensuring stable performance under dynamic loads.
- Low Maintenance: Sealed design prevents moisture ingress and corrosion, reducing the need for regular inspections and replacements.
- Customizable Dimensions: Available in various lengths, widths, and thicknesses to meet specific project requirements. Custom shapes (e.g., circular, rectangular) are also available on request.
- Easy Installation: Lightweight design and standard dimensions allow for quick installation without specialized equipment.
| Parameter | Standard Value | Remarks |
|---|---|---|
| Hardness (Shore A) | 60 ± 5 | Customizable upon request |
| Compressive Modulus | ≥ 2.0 MPa | At 5% strain |
| Shear Modulus | ≥ 0.8 MPa | At 25% strain |
| Tensile Strength | ≥ 15 MPa | Per ASTM D412 |
| Elongation at Break | ≥ 400% | Per ASTM D412 |
| Bond Strength (Rubber to Steel) | ≥ 7 kN/m | Per ASTM D429 |
| Temperature Range | -40°C to +100°C | Continuous operation |
These specifications ensure that the bearing pad can withstand heavy traffic loads, resulting in long service life for bridges. The neoprene material also provides excellent damping characteristics, reducing the transmission of vibrations to the superstructure and improving ride comfort for vehicles.
Advantages for Your Project
- Cost-Effective: Compared to traditional steel bearings, our elastomeric pads are more affordable to produce and install, reducing overall project costs.
- Low Noise: The rubber compound naturally absorbs sound, making it ideal for bridges in urban areas where noise pollution is a concern.
