Pot Type Rubber Bearing is a kind of new type bearing which is composed of pot, elastomeric pad, stainless steel plate, sealing ring and other components. It is designed for bearing the combinations of vertical loads, horizontal loads, longitudinal and transverse displacements and rotations. Pot bearing is ideal bearing for large bridge with the features of large horizontal displacement, light weight, simple structure and easy operation.
Pot-type rubber bearings are key load-bearing and force-transferring devices widely used in large and medium-span bridge engineering. They are particularly suitable for bridges requiring high load capacity, large rotation angles, and significant displacement accommodation. Their working principle is based on the three-dimensional confinement of the rubber block by the semi-enclosed steel pot and low-friction sliding mechanisms. The core design concept is to “combine the flexibility of rubber with the rigidity of steel, achieving restraint in specific directions while allowing movement in others.”
