Oil-free self-lubricating graphite copper sleeves are mainly used in automobile chassis, metallurgical machinery, mining machinery, water conservancy machinery, construction machinery, agricultural machinery, steel rolling equipment, etc. So, what are the advantages of graphite copper sleeve? Let's find out below!
No or less oil lubrication, suitable for places where it is impossible or difficult to refuel. It can be used without maintenance or less maintenance.
Good wear resistance, low friction coefficient and long service life. It has an appropriate amount of elastoplasticity, which can distribute the stress on a wider contact surface and improve the bearing capacity of the bearing.
The static and dynamic friction coefficients are similar, which can eliminate crawling at low speeds, 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 during operation, which can protect the grinding shaft without the phenomenon of shaft biting. For grinding shafts, the hardness requirements are low, and shafts that have not been quenched and tempered can be used, thereby reducing the difficulty of processing related parts. The technical characteristics of graphite copper sleeves are constantly improving.
