Product Description

Product Description

    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.

Structure

The laminated rubber bearing pad can be divided into standard laminated bearing pad and sliding laminated bearing pad.

    *Standard laminated rubber bearing pad is composed of natural or chloroprene rubber and reinforced steel plates.
    *Sliding laminated bearing pad is composed of natural or chloroprene rubber, reinforced steel plates and PTFE sliding plate.

Specification
