<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device having suppressed vibration. <P>SOLUTION: A bearing 101 has an outer ring 50, an inner ring 51, a plurality of rolling elements 52 laid between the outer ring 50 and the inner ring 51, and a cage 53 for holding the rolling elements 52. The rolling elements 52 are rollers cylindrically formed of bearing steel such as SUJ2, each having a hollow portion 54. The hollow portion 54 stores first and second vibration dampers 55, 56 whose natural frequencies are mutually different. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
