MAX POT BEARINGS
Pot bearings are built to withstand big loads and simultaneous large deformation in any direction, while allowing for minor rotations (<0.03 rad) in any of the bearing’s axes. A completely encased rubber pad is positioned in a steel pot; under high pressure the pad behaves like a liquid; elasticity of rubber allows tilting movement (rotation) of the piston in the horizontal axis. Movement capacity is obtained by coupling a sheet of a low friction material (for example PTFE) with a stainless-steel surface. Depending on the configuration, they can accommodate horizontal loads as well as movements in longitudinal or/and transversal directions.
This kind of bearing can withstand vertical loads of up to 100.000 kN.
The reference European Standard Code is EN 1337-5.
