POT Bearing for Bridges
POT bearing was developed in 1959 as an alternative to heavy steel sliding bearings. It consists of a circular non-reinforced rubber-pad fully enclosed in a steel pot.
POT-PTFE BEARING- In POT-PTFE(PolyTetraFluoroEthylene) bearing, two most important synthetic materials i.e. Elastomer & PTFE are utilized. Elastomer has an excellent property of providing translation and rotation without any moving parts. In POT-PTFE bearing, the latter part is utilized by completely encasing the elastomer pad in steel casing or POT. PTFE has an excellent property of having very low coefficient of friction and in the free end, a sliding component is added on top of POT, comprising stainless steel and PTFE for translation. The rotation, therefore, is provided by elastomer due to differential compression and translation by steel and PTFE.
Types?of?Pot Bearing:
According to the displacement ability, pot bearing can be divided into three types:
>Fixed pot bearing: The internal sealing ring enables the piston to rotate under load. This pot bearing has rotational performance, but limits all displacements of the plane shaft.
>Guided sliding pot bearing: The structure of the guide sliding pot bearing is the same as that of the free sliding bearing, but two guide rails are fixed on the top steel plate to limit the movement of the bearing bush.
>Free sliding pot bearing: These multi-directional devices are equipped with pure PTFE plates in contact with austenitic steel plates, so that the bearing?can slide in all directions.
