| abstract |
The invention provides a grease composition for constant velocity joint containing the components (a) to (g) below and a constant velocity joint containing said composition. n (a) a diurea thickening agent having the following formula (1):n nR 1 NH—CO—NH—C 6 H 4 - p -CH 2 —C 6 H 4 - p -NH—CO—NHR 2 (1)n nwherein R 1 and R 2 may be the same or different and represent C 8 -C 20 alkyl groups, (b) an ester synthetic oil, (c) a mineral oil and/or a synthetic hydrocarbon oil, (d) a molybdenum dialkyldithiocarbamate, (e) molybdenum disulfide, (f) a polytetrafluoroethylene, and (g) a zinc dithiophosphate compound. The grease composition of the invention reduces variations in rotational resistance of the constant velocity joint at a low temperature. |
