Abstract: A bearing system may have an inner race coupled to an outer race defining a lubrication volume and a shield coupled to the outer race, the shield at least partially defining an aperture of the lubrication volume. The aperture may permit the flow of lubricating oil through the bearing system. The shield may retain a quantity of oil within the bearing system. The bearing system may be operated without an oil supply, for example, during an emergency, and the retained quantity of oil may provide ongoing lubrication.

Abstract: A ball bearing has an outer race and an inner race A plurality of ball members are supported radially between the inner and outer races. A pair of bearing cage halves are placed at axial ends of the balls. The bearing cage halves are formed of a first relatively hard material, and have a plating of a softer material on some surfaces The bearing cage halves have pockets facing the balls and with the soft plating The bearing cage halves are riveted together along a contact surface, not including the soft plating. The rivets extend through an aperture in each of the bearing cage halves, not provided with the soft plating. The rivets have heads extending into a ditch, not provided with the soft plating. A rotor sub-assembly, a generator, and a method of maintaining a generator are also disclosed.
