We are excited to introduce our Chloroprene Rubber Bridge Bearing, engineered to meet the rigorous demands of modern bridge construction. As a manufacturer based in Hengshui, Hebei, China, with over 5 years of industry experience and a factory spanning 1,000-3,000 square meters, we pride ourselves on delivering high-quality, durable solutions. This bearing, compliant with ASTM D4014, offers a 1500kN load capacity and operates reliably from -40°C to 70°C, making it an ideal choice for diverse climatic conditions. Our commitment to precision and performance ensures that your bridge structure benefits from superior load distribution, vibration isolation, and long-term stability.
Crafted from premium chloroprene rubber (neoprene), this elastomeric bearing pad provides exceptional resistance to aging, ozone, and weathering. The 1500kN capacity allows it to support heavy loads while accommodating thermal expansion, contraction, and rotational movements. Whether used in highway bridges, railway overpasses, or pedestrian walkways, our bearing enhances structural safety and extends service life. Below, we detail its key features and technical specifications.

Benefits to Your Project: By using our chloroprene rubber bridge bearing, you gain improved structural integrity, reduced maintenance costs, and enhanced safety. The bearing effectively absorbs vibrations and noise, protects the bridge deck from thermal stresses, and simplifies installation due to its lightweight and flexible nature. Compared to conventional steel bearings, it offers superior corrosion resistance and lower life-cycle expenses.
Our manufacturing process adheres to strict quality control, with each bearing tested for dimensional accuracy, mechanical properties, and performance under simulated loads. We offer customization options including size, shape, number of internal steel layers, and even color (if requested). Our team works closely with engineers to ensure the bearing meets your specific design requirements.
Frequently Asked Questions (FAQ)
- What is the warranty period for this bridge bearing? We provide a standard warranty of 12 months from the date of shipment, covering manufacturing defects. Extended warranty options are available upon request.
- Can the bearing be used in seismic zones? Yes, our chloroprene rubber bearing is designed to accommodate moderate horizontal displacements and rotations, making it suitable for seismic-prone areas when combined with proper design considerations.
- What is the typical lead time for production? For standard sizes, lead time is 15-20 working days. Custom orders may require 25-30 working days depending on complexity.
