Sintered Oil-impregnated Bearings

A sintered oil-impregnated bearing is a sliding bearing in which a porous metal body manufactured with powder metallurgy methods is impregnated with oil, meaning the bearing lubricates itself during use. The oil inside the bearing forms a lubricating film when it seeps out to the sliding surface due to the pumping action and heat resulting from the revolution of the shaft.
