Pot bearings are commonly classified into three types based on their degree of freedom: fixed, guided, and free sliding. They allow for rotation because the base pot and rubber pad can rotate against each other. Fixed and guided bearings are designed to support horizontal loads. In guided and free sliding bearings, the Teflon plate and stainless steel plate form a sliding surface, which allows for the horizontal movement of the superstructure. Additionally, pot bearings can be equipped with anti-uplift devices according to structural requirements. Pot bearings are widely used in the construction of bridges due to their reliable behavior and simple mechanism.
