ABSTRACT:
A grease composition for constant velocity joints consists essentially of: (a) a base oil; (b) an urea thickener; (c) molybdenum disulfide; (d) a calcium salt or an overbasic calcium salt selected from the group consisting of calcium salts or overbasic calcium salts of oxidized waxes, petroleum sulfonates, alkyl aryl sulfonates, salicylate, and phenates; (e) a metal-free sulfur-phosphorus extreme pressure agent; and (f) molybdenum dithiocarbamate. The grease composition exhibits excellent wear-resistance and pitting-inhibitory effect.
