How to use graphite copper sleeve bearing

Working principle of graphite copper sleeve: general solid lubricant accounts for 20-30% of friction surface area. The lubrication principle of graphite copper sleeve self-lubricating bearing is that in the process of sliding friction between shaft and bearing, some graphite particles are transferred to the friction surface of shaft and bearing to form a relatively stable solid lubrication film to prevent direct adhesion and wear of shaft and bearing. This reasonable combination integrates the respective performance advantages of metal alloy and nonmetal antifriction materials, and complements each other, which not only has the high bearing capacity of metal, but also obtains the lubrication performance of antifriction materials. Therefore, it is especially suitable for environments such as no refueling, little refueling, high temperature, high load or water. Knowledge extension: graphite copper sleeve, also known as self-lubricating bearing, is a product with self-lubricating performance, which takes copper sleeve as metal matrix, develops holes with orderly arrangement and appropriate size on the friction surface, and embeds graphite or molybdenum disulfide as solid lubricant. At present, graphite copper sleeve has been widely used in construction machinery, metallurgical machinery, mining machinery, locomotive support, steel rolling equipment, marine machinery, mold equipment, textile machinery, gas turbine and other low-speed heavy-load and high-speed light-load occasions.
