Product Description

 

Product Description

 

It is made of rubber and sandwich steel plates layered and bonded by high-temperature vulcanization. 
It has a large vertical load-bearing capacity and a small horizontal stiffness. It is generally used to support the weight of structures, connect upper and lower structures, and play a role in blocking the upward propagation of earthquake horizontal motion energy.
The laminated rubber bearing is a new type of bridge bearing with the advantages of simple structure, easy processing and manufacturing, less steel consumption, low cost and easy installation.
