    摘要: 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.
