An object of the present invention is to provide a grease composition having excellent rust prevention, extreme pressure, water resistance, lubrication life, and conductivity. Further, the present invention provides a rolling device having a long life even when used under severe conditions. An organic bentonite and a second thickener component (metal soap, metal composite soap, polyurea, fluororesin) are formed in a gap formed between an inner ring 1 and an outer ring 2 of a ball bearing and in which a ball 3 is disposed. , N-substituted terephthalamic acid metal salt, calcium sulfonate complex, or carbon black) as a thickener.
