Abstract (en)

[origin: WO2008040381A1] To solve the problem to provide for a new grease composition giving low wear and low friction primarily to constant velocity joints, a grease composition is suggested comprising a) a base oil composition; and b) 0,25 % by weight to 5 % by weight of at least one tri-nuclear molybdenum com pound of the formula Mo<SUB>3</SUB>S<SUB>k</SUB>L<SUB>n</SUB>Q<SUB>Z1 </SUB>wherein L are independently selected legends having organo groups with a sufficient number of carbon atoms to render the compound soluble or dispersible in the oil, n is from 1 to 4, k varies from 4 though 7, Q is selected from the group of neutral electron donating compounds such as amines, alcohols, phosphines, and ethers, and z ranges from 0 to 5 and includes non-stoichiometric values.
