GREASE COMPOSITION

摘要

PURPOSE: To obtain a grease compsn. which improves the acoustic properties of a bearing at a high temp. and is suitable for prolonging the life of acoustic properties from a high to a low revolution speed. CONSTITUTION: This grease compsn. comprises 5-20wt.% thickening agent comprising 0-60wt.% lithium salt of a 12-24C fatty acid having no hydroxyl group and 40-100wt.% lithium salt of a 12-24C hydroxylated fatty acid and 80-95wt.% base oil having a kinematic viscosity at 40 deg.C of 80-300mm<2> /sec and contg. at least 10wt.% ester oil.
