SIM Lines (Bushings in Bronze)

Systems Exempt from Lubrication - Bushings in Bronze

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.

SIM-63

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.
