PROBLEM TO BE SOLVED: To provide a conductive rolling bearing having a longer life in use under high temperature conditions and hardly permitting the leakage of a grease composition and base oil. SOLUTION: In a cavity where rolling elements 3 formed between an inner ring 1 and an outer ring 2 of a deep groove ball bearing are arranged, the conductive grease composition 6 is filled which contains the base oil and a thickener. The base oil of the conductive grease composition 6 mainly contains fluorine oil, and the thickener contains graphite and carbon black. The ratio of the amount of the graphite to the total amount of the graphite and the carbon black is 20-90 mass%. COPYRIGHT: (C)2009,JPO&INPIT |
