Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019 with a 1,000–3,000 m² factory and ISO9001/ISO9000 certified, proudly presents our Multi Layered Elastomeric Seismic Isolation Bearing for Bridges High Damping Rubber. This advanced bearing is engineered to protect bridge structures from earthquake damage by absorbing and dissipating seismic energy. With over 101–200 skilled employees and an annual export value of US$2.5–5 million, we deliver reliable, cost-effective solutions to markets worldwide including North America, Europe, and Southeast Asia. Our product combines multi-layer elastomer design with high damping rubber to provide superior stability, durability, and isolation performance.
This bearing consists of alternating layers of high-damping rubber and steel plates, vulcanized together to form a compact unit. The rubber layers provide flexibility and energy dissipation, while the steel plates ensure vertical load capacity. The high damping rubber compound offers excellent damping characteristics (typically 10–20%), reducing the transmission of horizontal seismic forces to the superstructure. Ideal for bridges, viaducts, and elevated highways, this product enhances structural safety and extends service life even under extreme seismic events.
Key Features & Technical Specifications

Frequently Asked Questions (FAQ)
-
What is the typical lifespan of your seismic isolation bearing?
Our bearings are designed for a service life of 50 years or more under normal conditions, thanks to the high-quality rubber compound and durable steel plates. -
Can you provide custom sizes for specific bridge projects?
Yes, we offer customizable dimensions, stiffness, and damping ratios to meet your project requirements. Please provide your design parameters for a tailored solution. -
How does the high damping rubber compare to lead rubber bearings?
High damping rubber bearings provide inherent damping without lead, making them more environmentally friendly and easier to handle. They offer similar isolation performance with lower maintenance. -
What certifications do your products have?
Our factory is ISO9001 and ISO9000 certified, and our products are manufactured in compliance with international standards. Specific third-party testing reports are available upon request. -
What is the maximum horizontal displacement your bearing can accommodate?
Depending on the size and design, our bearings can accommodate lateral displacements up to ±200 mm or more. Custom designs for larger displacements are available. -
Do you offer installation support or technical guidance?
Yes, we provide installation manuals, technical drawings, and remote support. For complex projects, on-site guidance can be arranged. -
What is the minimum order quantity (MOQ)?
Our MOQ is typically 10 pieces for standard sizes, but we can discuss smaller quantities for sample or trial orders. -
How long does delivery take?
Standard lead time is 15–30 days after order confirmation, depending on quantity and customization. We ship from Tianjin or Qingdao ports.
