摘要： The present disclosure is related to provide a lubricating grease composition having a high static friction coefficient while maintaining excellent low-temperature torque characteristics, high-temperature shear stability, and high-temperature oil separation characteristics.A lubricating grease composition of the present disclosure contains a base oil, a thickener, and a solid lubricant, wherein the solid lubricant is calcium carbonate, the amount of the calcium carbonate blended is 1 to 60% by weight based on the total weight of the lubricating grease composition, the calcium carbonate has an average particle diameter of 0.1 to 30 μm, the base oil has a kinematic viscosity of 18 to 300 mm2/s at 40° C., and the lubricating grease composition has a worked penetration of 240 to 320.

摘要： A lubricating grease composition containing a base oil having a kinematic viscosity of 10 mm2/s or more and 60 mm2/s or less at 40° C.; a thickener containing at least one soap selected from a metal soap and a metal complex soap; and a solid lubricant containing porous polyamide particles. An amount of the porous polyamide particles blended is 1% by mass or more and 20% by mass or less based on a total mass of the lubricating grease composition.
