The laminated elastomeric bearing is an elastomeric rubber block reinforced with steel plates vulcanised when built.

This bearing is the connection between a structure and its support, and should make the following possible through elastic deformation:

  • transmission of normal forces;
  • horizontal movements (if that is the case);
  • in case of structure rotation in any direction (if that is the case);
  • in case transmission of horizontal forces, within defined limits (if that is the case).

Types of elastomeric bearings:

  • standard bearings;
  • bearings with anchor plates;
  • bearings with sliding surface;
  • restrained bearings.

The tetron CD bearing is composed of an elastomer disk confined in a cylindrical space limited by a hollow base and a piston. Thus it behaves like an uncompressible liquid and can transmit very high loads and absorb rotations of the structure.


  • resistance from low to very high vertical loads;
  • transmission of high vertical and horizontal forces within small overall dimensions;
  • high amplitude movement capacity in one or two horizontal directions with a very low coefficient of friction and without any elastic return force;
  • high rotation amplitude along any horizontal axis, with a low resisting moment;
  • very high resistance to dynamic loads.

Types of Tetron bearings:

  • Tetron CD/FX
  • Tetron CD/GL (free sliding)
  • Tetron CD/GG (guided sliding)
  • Tetron CD special – any of the types above can have a special, anti-uplift feature.
