Description
Reinforced Laminated Rubber Bearing 

Elastomer Bearing Pad are made of multiple layers of rubber sandwiched with and bound to thin steel sheets,and then through vulcanization.Its vertical rigidity is sufficient to bear the perpendicular load and to shift the pressure reliably from the superstructure to the piers. Its elasticity is high enough to suit the rotation of the beam end.Its shear deformation is sufficient to cope with the horizontal displacement of the superstructure.
