Patent ID: 7053028

Claim:
A grease comprising: a base oil a thickener, and an amide-based wax, wherein the amide-based wax is contained in an amount of 0.5 to 10% by weight based on the total weight of the grease, has a melting point of 80° C. or more, and an antioxidative ability to the base oil, wherein the base oil is at least one base oil selected from the group consisting of an ether-based oil, an ester-based oil and a synthetic hydrocarbon oil, and has a kinematic viscosity of 20 to 150 mm 2 /s at 40° C., wherein the thickener is an urea-based thickener, and is contained in an amount of 5 to 30% by weight based on the total weight of the grease wherein the amide-based wax is represented by the following formula (II): R 3 CONHR 4 CONHR 5 (II) where R 3 , R 4 , and R 5 are aliphatic groups.
