Bridge Bearing

Bridge Bearings are essential structural components installed between a bridge’s substructure (such as piers or abutments) and its superstructure (including girders or deck slabs). Their primary role is to safely and efficiently transfer loads from the superstructure to the substructure, ensuring the bridge remains stable and functional under various conditions.

These loads include vertical forces from the bridge’s own weight and vehicle traffic, as well as horizontal forces caused by thermal expansion, braking, wind, and seismic activity. By accommodating these movements and forces, bridge bearings help protect the structure and prolong its service life.

There are four main types of bridge bearings commonly used in modern bridge construction: Disc Bearings, Pot Bearings, Spherical Bearings, and Elastomeric Bearing Pads.
