Oil free self lubricating graphite copper sleeve is mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc. So, what advantages does graphite copper sleeve have? Let's learn about it!
No oil lubrication or less oil lubrication, suitable for the places where it is impossible or difficult to add oil. It can be used without maintenance or less maintenance.
Good wear resistance, small friction coefficient and long service life. With a proper amount of elastic-plastic, the stress can be distributed on a wide contact surface and the bearing capacity can be improved.
The static and dynamic friction coefficient is similar, which can eliminate the crawling at low speed, so as to ensure the working accuracy of the machine. It can reduce vibration, noise, pollution and improve working conditions.
The graphite copper sleeve can form a transfer film in the process of operation, which can protect the grinding shaft and avoid the phenomenon of shaft biting. The hardness requirement of grinding shaft is low, and the shaft without quenching and tempering treatment can be used, which reduces the machining difficulty of related parts. The technical characteristics of graphite copper sleeve are constantly improving.
