The spherical bearing used on bridge,the loading capacity can be produced during 1500-60000 KN, The structure, specification, technical requests, material performance requests of bridge spherical bearing needed to be comply with regulatory requirements.

Earthquake is one of the terrible natural calamities,although we can not prevent earthquakes, but we can reduce the damage caused by earthquakes by using seismic isolation, lead rubber bearings are widely used on bridge construction, as well as building construction, now we have Mature production processes of LRB,

We need to follow the installation order of the lead rubber bearing, The installation construction order for the building lead rubber bearing is from the bottom to the top, that is to say, we must finish the construction of the substructure components or base of the LRB

The designing of elastomeric bearing pad, except vertical loading request, we also need to consider material choose, designing of shape,stiffness, and Temperature influence
