Abstract

Provided are a grease composition which inhibits simultaneously a bearing wear and a fretting wear under a high load to make it possible to elongate a life of the bearing; a grease composition which can inhibit a fretting wear caused by a change in a load in a thrust direction in addition to an usual fretting wear caused by small vibration in an oscillating direction; and a grease composition which is excellent in low-temperature characteristics. The grease compositions contain a base oil and a thickener, wherein the base oil contains a poly-±-olefin (component A) which has a kinetic viscosity of 300 mm 2 /s or more at 40°C and which is produced by using a metallocene catalyst.
