Seismic Isolation Bridge Support Rubber Elastomeric Bearing Pad

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Seismic Shock Absorption: Designed to isolate and absorb seismic vibrations and shocks in bridge structures, protecting against earthquake-induced damage.
  • Load Distribution: Distributes heavy vertical and horizontal loads between bridge decks and piers, ensuring structural stability under dynamic conditions.

Key features

  • 1. Advanced Material Technology

    • With a corrosion-resistant metal body combined with high-performance rubber composites (CR, EPDM, SBR, NBR), you can ensure durability in harsh industrial and bridge environments. The chemical-treated rubber layers provide superior resistance to UV, ozone, and extreme temperatures compared to conventional rubber bearings*.

  • 2. Customizable Interactive Design

    • With modular mounting flanges and pre-drilled holes for precise alignment, you can easily integrate the bearing into diverse structural configurations. This adaptability outperforms rigid, non-modular designs in accommodating site-specific requirements*.

  • 3. High-Performance Load Capacity

    • With a load capacity engineered to withstand seismic forces and heavy bridge loads, you can achieve up to 20% greater weight distribution efficiency than standard elastomeric bearings*. The circular pattern ensures uniform stress dispersion for long-term stability.

  • 4. Seismic Scenario Solutions

    • Designed for critical seismic isolation in bridge infrastructure, you can mitigate structural damage during earthquakes by absorbing vibrations and displacements. This specialized functionality is unmatched in non-seismic-grade bearing systems*.

  • 5. Certified Industrial Compliance

    • With compliance to international standards for bridge engineering and industrial safety (e.g., ISO, ASTM), you can guarantee regulatory adherence and reliability in high-stakes applications. These certifications surpass basic rubber product requirements*.
