摘要：
A grease composition for constant velocity joints which consists essentially of: (a) a base oil; (b) a diurea compound represented by the following general formula:R.sup.1 NH--CO--NH--p--C.sub.6 H.sub.4 --CH.sub.2 --p--C.sub.6 H.sub.4 --NH--CO--NHR.sup.2(wherein R.sup.1 and R.sup.3 may be the same or different and each represents an aryl group or a cyclohexyl group); (c) melamine cyanurate; (d) molybdenum disulfide; and (e) a phosphorus-free sulfur extreme pressure agent, and optionally (f) molybdenum dithiocarbamate.The grease composition exhibits excellent pitting-inhibitory effect and heat resistance.
