PROBLEM TO BE SOLVED: To provide a rolling bearing for a business machine having high corrosion resistance and reducing the deterioration with age of electrical conducting properties. SOLUTION: A ball bearing 1 comprises an outer ring 2 made out of martensite stainless steel and assembled in a housing made out of a resin, an inner ring made out of SUJ2, and a steel ball 4 for the bearing harder than the martensite stainless steel. The electrically conductive grease 7 is packed in a void part formed between the outer ring 2 and the inner ring 3. COPYRIGHT: (C)2005,JPO&NCIPI |
