These are structural bearings consisting of an elastomeric core in which one or more steel laminates are inserted, hot vulcanized to the rubber.
The presence of the laminates determines a vertical (axial) stiffening effect and the simultaneous reduction in the rubber swelling. Curing has two purposes: one is to convey the rubber tangential actions to the laminate and the other is to ensure the protection of steel against corrosion.
