Abstract
The grease composition for constant velocity joints of the invention is characterized by comprising a lubricating base oil, a thickener, carbon black with a mean particle size of not greater than 500 nm, and an organic molybdenum compound. A grease composition for constant velocity joints according to the invention can achieve a highly satisfactory balance between anti-flaking, anti-seizure and anti-wear without using lead compounds, and can sufficiently maintain these properties with long-term use.
