本发明提供一种流体轴承用润滑油组合物，该组合物含有50～100％质量具有至少一个醚键的碳原子数为11～34的醚化合物作为基油、且温度100℃时的运动粘度为2.2mm 2 /s以上，具有低温流动性良好、且即使在高温区域粘度下降也少等优异的粘度特性，同时具有低蒸发性、节能性和耐热稳定性等，适合在高速旋转下所使用的小型流体轴承中使用。

Water-soluble metalworking fluid

Phosphorus, nitrogen and sulfo-containing additives

Compositions made by reaction of (A) at least one phosphorus acid compound of the formula: ##STR1## wherein each X is independently oxygen or divalent sulfur, M is hydrogen or an equivalent of metal or ammonium cation, R is a hydrogen atom or a hydrocarbyl or hydrocarbyloxy or hydrocarbyl mercapto group of about one to about thirty carbon atoms and R' is XM or R with the proviso that the total number of carbon atoms in both R and R' is at least two, with (B) at least one sulfo-containing compound of the formulae: ##STR2## wherein y is one or two, R 3 is hydrogen or lower alkyl group, R 2 is a divalent or trivalent hydrocarbyl group, R 4 is a trivalent hydrocarbyl group, and Q is --OH, --OR 3 , --OM, an alkylene polyamine residue, or N(R 3 ) 2 , are novel and useful and have utility as, for example, additives for water-containing hydraulic fluids.
