  • an inner race;

    an outer race; and

    an array of rolling elements arranged within a bearing cage situated between inner race and the outer race, an inner surface of the bearing cage being piloted on the inner race for limiting eccentric movement of the bearing cage within the bearing, and further having a reservoir formed between a pair of circumferential weirs on the bearing cage, an outer surface of the inner race comprising a raised land portion for contacting oil in the reservoir thereby to control a relative speed of the bearing cage and the inner race, whereina radial depth of each of the weirs is greater than a maximum radial clearance between the land portion and the bearing cage for maintaining a controlling contact between the land portion and the oil during the eccentric movement of the bearing cage,one or more of the weirs are detachable for permitting axial disassembly of the bearing cage from the inner race, andone or more of the detachable weirs are in a form of a resilient ring element that engages the inner surface of the bearing cage in a compression fit.
