LUBRICATING GREASE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a novel lubricating grease composition which exerts a stable effect in reducing the friction coefficientμwithin a wide temperature range, does not affect synthetic resins and is therefore suitably used for devices using members made of synthetic resins, e.g. a reducing gear of an electric power steering device, etc. SOLUTION: The lubricating grease composition is prepared by compounding a fluororesin powder at a compounding ratio F (pts.wt.) that satisfies the formula: W<=F<=(W+30) [wherein W is the compounding ratio (pts.wt.) of a thickener against 100 pts.wt. base oil] with 100 pts.wt. base oil.
