Pot bearings

Pot, Spherical and linear-Rocker bearings, up to 5000 Mton capacity



TGa Multidirectional bearings

sThese bearings are used for movements in both ways. “x” and “y” direction. They are able to resist and transmit external horizontal forces like seism.

TGe Unidirectional bearings

This kind of bearings are used for just one direction movements. They are capable to resist and transmit forces on the direction the movement is restricted.

TF Fixed bearings

The fixed bearings does not allow any movement: They are are used to transmit horizontal forces in any direction.

 

Elastomeric Pads

Laminated bearings may be molded to any shape or size depending on the design requirements. Internal steel plates may vary in thickness and are vulcanized-bonded during the molding process.

The pads fulfill all AASHTO specifications: the compression and the low temperature resistance, the adhesion and the deflection.

Product presentation: bonded to load plates, rectangular, circular, beveled, clipped cornes and skewed.
