Shimmed Elastomeric Bearings

Laminated Steel Elastomer Bearing Pads are now in service in tens of thousands of bridges and similar structures throughout the world.

Laminated elastomeric bearing pad, one type of reinforced elastomeric bearings, is made of multi-layer rubber and reinforced with steel plate through sulfuration and adhesion. Compared with non-reinforced elastomeric bearing, it has sufficient vertical rigidity which can reliably transfer the concentrated down-loads and impact loads of the superstructure to both ends of the pier. What’s more, laminated elastomeric bearing pad not only has fine elasticity which can adapt the rotation of beam end but also has great shearing deformation capacity which can satisfy the horizontal displacement of the superstructure. Thus, it is often applied for steel bridge, PC bridge, RC bridge including right, curved, or skew angled bridge.
