<p>The present application relates to a grease composition, more particularly, to a grease composition for a constant velocity joint or a ball joint for a vehicle and, even more particularly, to a grease composition containing 70 to 80 parts by weight of a paraffinic base oil; 7.5 to 17.5 parts by weight of a urea-type thickener; an extreme pressure-wear additive containing 1 to 2 parts by weight of molybdenum dithiocarbamate and 1 to 2 parts by weight of zinc alkyl dithiophosphate; a lubricant containing 0.5 to 1.5 parts by weight of animal and vegetable oils and 0.5 to 1.5 parts by weight of calcium sulfonate; 0.5 to 1.5 parts by weight of a dispersing agent; and 0.5 to 1.5 parts by weight of a structural stabilizer. According to the present application, grease that has excellent high-temperature and low-temperature characteristics, has excellent durability to allow long-term lubrication, contributes greatly to temperature rise prevention by reducing sliding friction, and has the optimal effect in constant velocity joints or ball joints for vehicles, gears for steel and other industries, bearings, and particularly lubrication sites requiring extreme pressure, can be provided.</p> |
