Product Description

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

As we all know, the bearing pad can be divided into elastomeric bearing pad and laminated rubber bearing pad according to different inner structure: elastomeric bearing pads and laminated rubber bearing pads. The elastomeric bearing pads are solid blocks of rubber without any steel reinforcement plates, which are not used in bridges. In this topic, we will introduce you the introduction, structure, classification, production line, features and applications about laminated rubber bearing. Just refer to them and know more about products and our company. If you need customized products, Contact our professional sales representatives, they will give you satisfied suggestion.

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

*Excellent accommodation for horizontal movement.

*Low friction coefficient.

*Absorb vibrations and isolate sounds.

*Easy to install.

*Completed products for suitable displacement requirements.

*Can be used in extremely low temperatures.

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.
