Provided is a rolling bearing device comprising inner races (2), outer races (3), rolling elements (4), a retainer (5), and an inner race spacer (6). The inner race spacer (6) is formed of an oil reservoir member (7) made of a sintered metal impregnated with lubricating oil, and a spacer cover (8) fitted onto an outer periphery of the oil reservoir member (7). Through a centrifugal force to be applied to the oil reservoir member (7) at the time of bearing rotation, the lubricating oil is scattered radially outward through a chamfered portion (7d) of the oil reservoir member (7) via an oil supply passage (S), to thereby lubricate the interior of the bearing with oil. |
