The present application relates to a grease composition, and more particularly, to a grease composition for a constant velocity joint or a ball joint for a vehicle. More particularly, the present application relates to a grease composition containing: 70 to 90 parts by weight of base oil that is a mixture of paraffin oil and naphthene oil; 7 to 18 parts by weight of a urea-type thickener; and 5 to 15 parts by weight of an additive. According to the present application, grease that has excellent high-temperature and low-temperature characteristics, excellent durability allowing long-term lubrication, and an excellent temperature rise prevention effect for reducing slip friction can be provided. The grease can have an optimal effect in constant velocity joints or ball joints for vehicles, gears or bearings used in the steel industry or other industries, and particularly lubrication places requiring extreme pressure. |
