The Grafimec bearings of Line SIM are exempt from oil and have solid permanent lubrication, they are ideal for critical combinations of load/speed and extremes of temperature, ensuring better conditions of sliding through the formation of permanent film that occurs right when starts the movement between a compound and the bearing.
Bronze alloy of high strength and hardness, used for applications of static high loads and extreme at low speeds. It has excellent resistance to corrosion and extreme temperatures.
Typical applications: steel, non-ferrous metallurgy, hydraulic sluice gates, butterfly valves.
