Abstract
A rolling bearing device includes a rolling bearing and an oil supply unit. The oil supply unit includes a lubrication oil tank, a pump which sucks lubrication oil from the lubrication oil tank and discharges the lubrication oil from a discharge porta driving section which drives the pump and a generator section which supplies the driving section with electric energy. The oil supply unit is attached to a fixed-ring-side member of the rolling bearing or a spacer adjacent to the rolling bearing. The oil supply unit further includes a communication unit which transmits operation information of the oil supply unit to an outside.
