PROBLEM TO BE SOLVED: To provide a rolling bearing to be suitably used under the conditions of high temperature, speed, load and vibration, having good rust proofing performance and superior peeling life without giving damages to human bodies. SOLUTION: A grease composition consists of composite oil as base oil, a diurea compound as a thickening agent, and at least one type of rust proofing additive selected from naphthenic acid zinc and succinic acid derivative to be 0.1-10 mass% of the total amount of grease. It is filled into a bearing space which is formed by an inner ring, an outer ring and rolling elements. COPYRIGHT: (C)2006,JPO&NCIPI |
