Product Description

Product Description

The bearing is composed of several layers of rubber sheet and thin steel plate superimposed by pressure vulcanization, which has enough vertical stiffness to meet the vertical load, and has good elasticity to adapt to the rotation of the beam end. It has large shear deformation to meet the water of the superstructure horizontal displacement, and has a good seismic effect, can reduce the dynamic load on the upper structure and pier impact.

Features of rubber bridge bearing:

(1) Quality materials including natural rubber, neoprene complying with AASHTO standards.

(2) Allow for expansions and contractions of precast steel structure of bridges.

(3) Capable to control load distribution, meanwhile accommodate thermal and end-beam rotational movements.

(4) Vibration, sounds and shocks isolation.

(5) Avoid excessive load eccentricity and edge compression.

(6) Simple but robust structure.

(7) Lower price than laminated elastomeric bearing.

(8) High cost effectiveness.

(9) Minimal maintenance is needed
