BARBIERI RUBBER also designs and manufactures rubber bellows to protect brake pumps and brake valves.
The bellows or boot protects the brake pump components from dust and other aggressive external agents, prolonging their average life. The rubber compound used is highly elastic and highly resistant to mechanical and chemical attacks, and it is also perfectly resistant to brake fluid and brake oil.
In this way, protection of the brake pump is ensured for many years even in severe weather conditions.
BARBIERI RUBBER has studied different shock absorber devices for electric motors and drive shafts; small rubber parts, suitably designed, have greatly increased comfort inside the car, not only in terms of noise level, but also of vibration transmitted to the person in the car by the many moving parts.
Rubber spring drives, apparently insignificant, but carefully designed and tested, silence the drive system and decrease mechanical stress. In the same way, bearing supports made from special materials and to special hardness levels can greatly reduce the noise produced by a ventilation system whilst increasing its reliability and durability.
Barbieri also produces many items installed in the engine, such as rubber manifolds, suction seals, and air and fuel pipes; items that require specialized rubber compounds due to the fact that they are in contact with aggressive substances, (oil or gasoline and fuel in general), and are operating in the presence of temperatures that in some areas may even compromise the working life of the component.
Furthermore, the rubber components near the engine must maintain good flexibility over time because vibrations cause mechanical stress in the rubber and speed up its deterioration.
