Bearings
Bearing devices are essential structural components for the correct transmission of loads between the various parts of a structure, while also allowing relative movements such as displacements and rotations.
Ronam Gomma Group offers reliable and certified solutions for the construction and maintenance of infrastructure, providing a high-performance range of bearing devices for bridges, viaducts, and civil or industrial buildings.
RG/A reinforced rubber bearings are designed to withstand vertical loads up to 20,000 kN, while simultaneously allowing movements and rotations in all directions thanks to the natural deformability of rubber.
Steel plates are embedded within the elastomer, perfectly bonded through a vulcanization process. These plates, are fully encapsulated in the rubber and therefore protected from atmospheric agents and corrosion.
RG/A bearings are supplied ready for installation and are designed to guarantee a minimum service life of 50 years. If not installed immediately, they must be stored properly, away from moisture, heat, and dirt.
Barring exceptional events, a visual inspection every five years is sufficient to verify the integrity of the rubber and the corrosion protection.
Ronamflon bearings, made of reinforced rubber and PTFE, consist of an elastomeric pad placed between two steel plates. Between the pad and the upper plate, a stainless steel sheet and a PTFE layer are interposed, allowing for low-friction sliding movements.
The lower plate is vulcanized to the elastomeric pad and equipped with anchoring systems (dowels, anchor bolts, screws) for integration with the structure. The internal plates, slightly smaller than the rubber layers, are completely embedded and protected.
These bearings are ideal for moderate vertical and horizontal loads and offer an economical and functional solution, especially suitable for structures requiring controlled movements and long-term reliability.
The RG/DISC bearing consists of a steel base with a rubber disc confined by an upper steel element. Rotation occurs through deformation of the rubber disc, while translations take place via the contact between two flat surfaces (PTFE - INOX), ensuring effective dissipation of mechanical stresses, fully embedded and protected.
