Publication number: 20090105103Abstract: A lubricating oil composition for use in oil-impregnated sintered bearings together with a resin member having C?C bonds or C?O groups in the molecules, which comprises a base oil comprising a synthetic hydrocarbon oil as the main component, and 0.1-30% by weight of an ester-based oil on the basis of total composition, and free from zinc dialkyldithiophosphate and molybdenum dialkyldithiocarbamate, where the synthetic hydrocarbon oil as the main component of the base oil has substantially no adverse effect on resin, can minimize an adverse effect on various metal species of sintered materials by suppressing a mixing amount of a wear inhibitor or an extreme pressure agent to a minimum, without deteriorating a good lubricability required for the lubricating oil in oil-impregnated sintered bearings.Type: ApplicationFiled: April 18, 2007Publication date: April 23, 2009Inventors: Miyuki Hashida, Wataru Sawaguchi, Toshio Nitta
