Abstract

A rolling-element bearing assembly includes a rolling-element bearing and an oil conditioning system for conditioning oil used to lubricate the bearing. The bearing has an inner ring and an outer ring and a plurality of rolling elements rotatably disposed between the inner ring and the outer ring. The bearing includes openings for discharging oil from the bearing and for introducing oil into the bearing, and the openings are connected to the oil conditioning system. A raceway of the inner ring and/or a raceway of the outer ring is coated with a first coating, and the rolling elements are at least partially coated with a second coating that is different from the first coating.
