<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device in which an absolute amount of a lubricant contributing to lubrication during rotation of the bearing can be easily increased without increasing the number of component items of the bearing. <P>SOLUTION: The rolling bearing device includes inner rings 2, outer rings 3, rolling bodies 4, retainers 5 and an inner ring spacer 6. The inner ring spacer 6 is formed of an oil-retaining member 7 that comprises a sintered metal impregnated with lubricating oil, and of a spacer cover 8 fitted to the outer perimeter of the oil-retaining member 7. Through centrifugal force generating in the oil-retaining member 7 when the bearing rotates, lubricating oil is scattered to the outer diameter side from a chamfer 7d of the oil-retaining member 7 via an oil supply route S to thereby lubricate the interior of the bearing with the oil. <P>COPYRIGHT: (C)2012,JPO&INPIT |
