PROBLEM TO BE SOLVED: To readily discriminate rolling bearings different in bearing specification such as the contact angle of rolling elements, a preload amount and the size of a radial internal clearance, even when bearing sizes are the same. SOLUTION: The rolling bearing 1 includes an inner ring 2, an outer ring 3 and the rolling elements 4 interposed between the respective rolling faces 2a, 3a of the inner and outer rings 2, 3. The rolling bearing 1 has a bearing component in a color defined according to the bearing specification. The bearing component is the rolling element 4 or a retainer 5, for instance. In this instance, preferably the rolling element 4 is made of ceramic and the retainer 5 of resin. COPYRIGHT: (C)2011,JPO&INPIT
