Abstract
A lubricating grease composition includes a base oil, a thickener, and a solid lubricant, wherein the base oil is a synthetic hydrocarbon oil with a kinematic viscosity of 600 to 2000 mm2/s at 40° C., the thickener is a barium complex soap, and the solid lubricant is an inorganic fine particle with Mohs hardness of 3 to 6 and an average particle size of 10 to 40 μm.
Claims15
A lubricating grease composition comprising 30 to 65% by weight of a base oil based on a total weight of the lubricating grease composition, 15 to 30% by weight of a thickener based on a total weight of the lubricating grease composition, and 10 to 60% by weight of a solid lubricant based on a total weight of the lubricating grease composition, wherein the base oil is a synthetic hydrocarbon oil with a kinematic viscosity of 600 to 2000 mm2/s at 40° C., the thickener is a barium complex soap, and the solid lubricant is an inorganic fine particle with Mohs hardness of 3 to 6 and an average particle size of 20 to 40 μm.
