High strength copper alloy (also known as JDB solid inlaid self smooth bearing) is mainly used as the matrix to replace the traditional oil groove copper sleeve by the method of embedding special formula solid smooth data into the matrix. It can be used in the environment where it is not easy to refuel, or is short of oil for a long time, which makes up for the lack of regular refueling for the traditional copper sleeve.
It has the characteristics of high bearing capacity, impact resistance, high temperature resistance, and strong self smoothness. It is especially suitable for heavy load, low speed, reciprocating or swing occasions where it is difficult to smooth and form oil film.
Because of its high hardness and strength, and low cost, its service life is twice as long as that of ordinary copper sleeve under low speed and heavy load, so it is favored by the majority of customers.
Working principle of graphite copper sleeve: the general solid smooth agent accounts for 20-30% of the conflict surface area. The smooth principle of graphite copper sleeve self smooth bearing is that in the process of sliding conflict between shaft and bearing, a part of graphite particles transfer to the conflict surface of shaft and bearing, forming a relatively stable solid smooth diaphragm to avoid direct adhesion and wear between shaft and bearing.
This reasonable combination combines the advantages of metal alloy and non-metallic antifriction data, and complements each other. It not only has the high carrying capacity of metal, but also obtains the smooth function of wear reduction data. So it is especially suitable for no oil, less oil, high temperature, high load or water environment.
Graphite copper sleeve, also known as self smooth bearing, is a kind of product with self smoothing function, which is developed on the conflict surface of copper sleeve as metal matrix, and embedded graphite or molybdenum disulfide as solid smoothing agent.
At present, graphite copper sleeve has been widely used in construction machinery, metallurgical machinery, mining machinery, locomotive support, steel rolling equipment, ship machinery, mold equipment, textile machinery, gas turbine and other occasions with low speed and heavy load, high speed and light load.
