A grease composition for a pivot assembly bearing is provided and includes a thickener of 5 to 25% by mass and a base oil of 95 to 75% by mass with respect to the total mass of the thickener and the base oil. Two or more ureas selected from: urea A: a urea comprising diurea compounds having an aliphatic (ALA)/alicyclic (ACA) substituent; urea B: a urea comprising diurea compounds having an alicyclic (ACA)/aromatic (ARA) substituent; and urea C: a urea comprising diurea compounds having an aromatic (ARA)/aliphatic (ALA) substituent are used as the thickener. A poly &#x3b1;-olefin mixture having a kinematic viscosity at 40&#xb0; C. of 40 to 70 mm/s prepared by mixing poly &#x3b1;-olefin (PAO HV) having a kinematic viscosity at 40&#xb0; C. of 350 to 450 mm/s with poly &#x3b1;-olefin (PAO LV) having a kinematic viscosity at 40&#xb0; C. of 25 to 40 mm/s in a mass ratio of 15:85 to 30:70 is used as a base oil. A lead free additive may be used as an additive.
