C.M.M. confined elastomeric disk supports POT
POT bearings are composed of an elastomeric disc encapsulated in a metal base plate (basement).
An upper plate (piston) works as a cap, covering the rubber disc and transferring the vertical load.
Rotation is possible by means of the deformation of the rubber disc.
As regards sliding bearings, the motion is possible by means of the sliding of an upper plate on a lubricated PTFE surface embedded in the piston. If the bearing must enable the motion along one single direction and withstand a side load in orthogonal direction, it can be “guided” by means of
a central guide bar embedded in the upper sliding plate.
POT bearings are designed in order to withstand high vertical and horizontal load values and ensure large displacements in any direction.
Their main features are:

POT bearings are designed in order to withstand high vertical and horizontal load values and ensure large displacements in any direction.
Their main features are:
- Vertical load up to 50.000 kN at the Ultimate Limit State (ULS) – Also negative loads can be withstanded
- Horizontal load up to 25.000 kN
- Great motion capability in any direction in the plane, if needed
- Rotation up to 0.02 rad
- High resistance to dynamic loads (e.g. seismic events) and fatigue cycles
- High durability (every steel component is covered with protective paint) and low need for maintenance
- Temperature range: -40°C ÷ +70°C
- The supports can be designed and installed on any type of structures
