| 摘要 |
The invention provides a grease composition for bearings used in wind power generators, containing a base oil which has a kinematic viscosity of 10 to 70 mm2/s at 40° C. and a pour point of−40° C. or less, and a diurea compound as a thickener, for example, a diurea compound represented by formula (1) where R1 and R2 are both C8-alkyl group. The grease composition for bearings used in wind power generators according to the invention can meet the requirements in terms of the seizure life and the pumpability as well as the fatigue life (flaking life). |
