摘要：
A grease is provided which has an improved inflow property of the grease into a lubrication unit and has a long life when used for bearings even under a high temperature environment.A grease composition comprising a base oil and a thickener, characterized in that the base oil contains an ester synthetic oil, the content of the ester synthetic oil is not less than 20% by mass of the total mass of the base oil and the thickener contains a diurea compound represented by the Formula (I): R1—NHCONH—R2—NHCONH—R3, (I) wherein R2 is a C6-15 divalent aromatic hydrocarbon group, R1 and R3 are the same or different, and represent cyclohexyl or C8-22 linear or branched alkyl, and the molar ratio of cyclohexyl to the total of cyclohexyl and C8-22 linear or branched alkyl is 60 to 95%.
