powder metallurgical oil bearing bushing 3*7*6mm for fan motor

Oil bearing in metal powder as the main raw material, by using powder metallurgy sintered body. It already have porous and can freely adjust the pore in the process of manufacturing the number, size, shape and distribution, etc. Use of the porous sintered body, and make it contain 10% ~ 40% (volume fraction) of lubricating oil, used in oil supply condition. Running, the shaft sleeve temperature, due to the expansion coefficient is larger than the metal oil, thus automatically to the surface of the sliding lubrication shaft sleeve.
