Bridge bearings are structural equipment or devices installed between bridge substructure and superstructure to transfer the applied load including earthquake loads; wind loads; traffic loads; and superstructure self-weight. Bridge bearings also makes rooms for relative movements between superstructure and substructure, for instance, rotation movements and translational movements in horizontal and transverse direction. Bearing used in the construction of bridge structure is divided into two major categories namely expansion bearings and fixed bearings. The former permits both translational and rotational movements whereas the latter allow rotational and limited translational movements. There are several types of bridge bearings which have been employed in bridge construction which are discussed below.

1.     Spherical Bearings

2.     Pot cum PTFE Bearings

3.     Elastomeric Bearings

4.     Rocker cum Roller Bearings
