Summary:PROBLEM TO BE SOLVED: To provide a grease composition for aerogenerator bearings capable of coping with not only fatigue life (release life) but also anti-seizing life and compressibility. SOLUTION: The grease composition for aerogenerator bearings contains a base oil having a kinematic viscosity at 40°C of 10-70 mm2/s and a pour point of -40°C or lower and a diurea compound, for example, a diurea compound represented by formula (1) (wherein R1and R2are both 8C alkyls) as a thickening agent.
