Use of an additive mixture in a lubricant composition for fluid dynamic bearing systems

摘要

The invention relates to the use of an additive mixture to increase the oxidation resistance in a lubricant composition for fluid dynamic bearing systems, which in addition to the additive mixture comprises at least one base fluid, the additive mixture at least one ionic liquid, the cation of which is substituted by an alkyl radical and the anion of which is essentially a is hydrophobic anion, and comprises at least one aminic antioxidant.
