Pot bearing, also known as pot rubber 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.
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.
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).
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.
Technical performance
Bearing capacity of the pot bearing is 100% of the design capacity and allow overloading 10%.
When working temperature changes from -25 °C to + 60 °C, the minimum design friction coefficient of pot bearing is 0.03. When working temperature changes from -40 °C to + 60 °C, the minimum design friction coefficient of pot bearing is 0.06.
The maximum rotation of pot bearing is 0.03 rad.
Working temperature
Normal temperature type: -25 °C to + 60 °C.
Cold resistance type: -40 °C to + 60 °C.
Feature
With low-profile but high loading capability over 50,000 kN than elastomeric bearing.
Shearing strength of elastomeric pad is increased through the method of encasing it in the steel pot.
Allow for large rotations ranging from 0 to 0.03 rad.
