GRAPHITE IMPREGNATED BRONZE BUSHING

WORKING PRINCIPLE & ADVANTAGES

• The working principle of a graphite impregnated bronze bushing and copper sleeve :Generally solid lubricant accounts for 20-30% of friction surface, graphite and copper set of self-lubricating bearing lubrication principle is in the process of sliding friction of shaft and bearing, part of the graphite particles transferred to the shaft and the bearing friction on the surface, formed a relatively stable layer of solid lubricant membrane, prevent the shaft and bearing directly adhesive wear. This reasonable combination of metal alloy and non-metal wear reducing materials of their respective performance advantages, complementary, that is, with the metal’s high bearing capacity, but also get the wear reducing material lubrication performance. Therefore, it is especially suitable for no refueling, less refueling, high temperature, high load or water environment.
• The application of graphite impregnated bronze bushing: Self-lubricating bearing, is the copper sleeve as a metal matrix friction surface to develop an orderly arrangement, the size of the appropriate holes, and embedded graphite or molybdenum disulfide as a solid lubricant, a self-lubricating product. At present, the graphite impregnated bronze bushing has been widely used in construction machinery, metallurgical machinery, mining machinery, locomotive support, steel rolling equipment, Marine machinery, die equipment, textile machinery, gas turbine and other low-speed heavy-duty, high-speed light load and other occasions.
