Pot Bearings are suitable for high loads, displacements and rotations. They can be designed and manufactured according to International Standards BS5400, AASHTO or AS5100.4. Pot Bearings basically consist of an elastomeric pad restrained in a metallic pot. The pad is then compressed by a piston with bearing pressures on or near to 30 N/mm2 and rotations up to (),03 rad, depending on the design standard required. When combined with sliding elements, movement capability can be provided in either one or both directions. Standard Pot Bearings are totally detachable, making them easy to dismantle if any element has to be replaced. Custom designed Pot Bearings can be manufactured to provide maximum perfor- mance characteristics.

Pot Bearings are split into three main types:

• Fixed (TF)
• Guided (TGe)
• Free (TGa)

The following tables describe these Pot Bearing types in reference to load, displacement and standard rotation paramete
