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 natural rubber (NR) certified in accordance with EN 1337-3 CE standards, either plain or reinforced with S235JR steel plates, are manufactured by vulcanizing an elastomeric layer bonded to a smooth or dimpled PTFE layer, topped with an AISI 304 stainless steel plate of suitable thickness.
The combination of PTFE and stainless steel allows translational movements with a low coefficient of friction, while ensuring reliable and durable performance over time.
In the reinforced version, the internal steel plates are completely embedded in the rubber, providing protection against external agents.
These bearings are ideal for moderate vertical and horizontal loads and represent an economical and functional solution, particularly suitable for structures requiring controlled movements and low sliding resistance.
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.
