PTFE Pot Type Rubber Bearing In Bridges
Pot bearing, also known as pot rubber bearing, basin rubber bearing or pot bridge bearing, with elastomeric bearing embedded inside of the steel plate, can be divided into fixed pot bearing, guided pot bearing and free sliding pot bearing. Pot bearings are special types of bridge bearings for taking large loads, large horizontal displacements and large rotation requirements in confined areas. The loading capacity of elastomeric bearings is limited, while pot bearings solved this problem, thus pot bearings are often regarded as suitable for use when bridges need large bearing reactions.
Common internal sturcture of pot bearing: anchor bolts, top steel plate, stainless steel slide, PTFE slide, elastomeric bearing pad, guided bar, bottom steel plate.
Classification of Pot Bearing
| A.Fixed pot bearing(code: (GD) | Fixed pot bearing is unmoved in all directions. Under loads, the elastomeric bearing pad behaves likes an incompressible confined fluid which enables the rotations on any axis. |
| B.Guided pot bearing(code: (DX) | Guided pot bearing with steel guide edge can be only moved in one direction. The stainless steel slide and PTFE slide further reduce the friction coefficient and guided pot bearing is used best when horizontal loads are relatively small (less than 20% of vertical Load). |
| C. Free sliding pot bearing(code: (SX) | Free sliding pot bearing can be movable in all directions. The added PTFE and stainless steel sliding surface between the piston and the sole plate creates a bearing assembly that allows horizontal movement in any direction. |
