Product Description

Product Description

Laminated Rubber Bearing – Standard and Sliding Types for Different Bridge Span

Bridge bearing acts as the core load-transfer medium connecting the superstructure to piers and abutments. Under vehicles, pedestrians and temperature variation, it transmits loads smoothly and releases displacement and rotation, keeping the bridge safe and quiet. Elastomeric bridge bearings laminated with rubber and steel provide softness and damping, while sliding bridge bearings equipped with stainless sliders and seals allow free movement and offer long-term, reliable support.

In harsh environments such as coastal salt spray, plateau UV or urban pollution, bridge bearings maintain flexibility and strength thanks to weather-resistant compounds and fully encapsulated construction, avoiding brittleness, corrosion or oil leakage and realizing a maintenance-free service life equal to that of the bridge. Designed to international standards and subjected to strict fatigue and seal tests, every bridge bearing delivers stable mechanical behaviour and lasting durability.

Introduction

    The laminated rubber bearing pads are made of several layers of natural rubber with reinforced steel inserted through sulfuration and adhesion. Laminated rubber bearings have enough stiffness and elasticity to transfer all load on bridge span structure to pier. Additional, it can bear the horizontal displacement, rotation and transformation caused by load.

    The laminated rubber bearing pads can reduce the pier vibration and accommodate the horizontal movement on the bridge span structure caused by the temperature changing and thermal expansion.

Features
    *3-D movement: ±200 mm longitudinal, ±50 mm transverse, 0.02 rad rotation
    *High damping & isolation: lead-rubber bridge bearing damping 15-25%, reduces seismic response by 40%
    *Ultra-low friction: PTFE sliding bridge bearing μ≤0.03 for smooth thermal movement
    *Weather & ageing resistance: anti-ozone rubber formula, UV and salt-spray proof, life ≥50 years
    *Maintenance-free: sealed steel pot prevents rubber exposure, no replacement needed within service life

Installation

Bridge bearings are widely used for:
    *Highway, urban expressway and viaduct concrete or steel box-girder supports
    *Main-tower lower cross-beam and girder connections of long-span cable-stayed, suspension and continuous rigid-frame bridges
    *Special tapered and spherical steel bridge bearings for curved, graded and skew bridges
    *Seismic isolation bridge bearings in zones ≥ magnitude 8 to improve urban resilience
    *Bearing replacement in existing bridge jacking and retrofit projects, minimizing road closure time with rapid-exchange systems
