Pot Bearing
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.

CE 0370-CPR-2609
- Customized design can be made according to the requirements and structure properties.
- Excellent durability and virtually maintenance-free.
- Easy for installation.
- Low total height, resulting in a low P-Δ effect.
Pot bearings are a type of structural bearings used in construction to support heavy loads. They are designed to allow the structure to move and rotate in response to external forces, and can also resist horizontal loads or uplift forces. It is important to note that they can be connected to both steel and reinforced concrete superstructures and substructures. Based on these characteristics, pot bearings are commonly used in the construction of bridges.
