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.
