    Abstract: A lubricant composition for oil-impregnated sintered bearings, which comprises at least one base oil selected from a perfluoropolyether oil represented by the following general formula: RfO(CF2CF2O)m(CF2O)nRf (where Rf is a perfluoroalkyl group having 1-5 carbon atoms, m+n=3-200, m:n=10-90:90-10), a perfluoropolyether oil represented by the following general formula: RfO[CF(CF3)CF2O]p(CF2CF2O)q(CF2O)rRf (where Rf is a perfluoroalkyl group having 1-5 carbon atoms, p+q+r=3-200, q and r each may be 0, and (q+r)/p=0-2), and a polyfluoropolyether oil represented by the following general formula: F(CF2CF2CF2O)sC2F5 (where s=2-100), and a fluorine-containing di- or mono-amide-based compound, has further improved lubrication characteristics, particularly wear resistance and friction coefficient characteristics, of perfluoropolyether oil.

    Abstract: A lubricant in the form of lubricating oil or grease, for use in contact with graphite or molybdenum disulfide or in contact with aluminum materials, which comprises a perfluoropolyether oil free from (CF2O)n groups as a repeat unit of polymer and having a kinetic viscosity at 40° C. of 50-1,500 mm2/sec., as a base oil, where F(CF2CF2CF2O)mC2F5 or RfO[CF(CF3)CF2O]p(CF2CF2O)qRf′ s used as the perfluoropolyether base oil. The lubricant undergoes no considerable deterioration of high-temperature characteristics (high-temperature durability), even if used in various uses as mentioned above, and also has distinguished low-temperature characteristics when the base oil has a kinetic viscosity of 50-250 mm2/sec.
