1. Elastomeric Bearings: These are the most common type of bearings used in bridges. They are made of high-grade rubber and steel plates, and they provide good flexibility and deformation capacity.
2. Pot Bearings: These bearings are made of a steel pot and a neoprene pad that sits inside it. They allow both vertical and horizontal movements of the bridge deck.
3. Disc Bearings: These bearings consist of a series of steel discs stacked on top of each other with a layer of Teflon between them. They provide good rotation capacity and allow for some horizontal movement.
4. Roller Bearings: These bearings consist of a series of steel rollers that sit inside a steel plate. They allow for horizontal and rotational movement of the bridge deck.
5. Spherical Bearings: These bearings consist of a steel plate with a spherical shape on the top and bottom. They provide good angular movement and are suitable for curved bridges.
6. Friction Pendulum Bearings: These bearings consist of a spherical steel pendulum that sits on a concave sliding surface. They provide excellent seismic resistance and allow for horizontal movement of the bridge deck.
