Patent ID: 7097362

Claim:
An electrocorrosion preventive rolling bearing assembly, comprising: an inner raceway member; an outer raceway member; at least one circumferential row of a plurality of rolling elements rollingly interposed between respective raceway grooves of the inner and outer raceway members; an electrically insulating layer formed on the outer raceway member to cover an outer peripheral surface and opposite annular end faces of the outer raceway member; wherein, positioned between one of the opposite annular end faces and an inner peripheral surface of the outer raceway member and uncovered by the insulating layer, a first step is recessed from the first annular end face such that a peripheral surface of the first step is located a first radial distance from the inner peripheral surface, and on the remaining opposite annular end face, there is defined either a second step, recessed from the remaining annular end face such that a peripheral surface of the second step is located the first radial distance from the inner peripheral surface, uncovered by the insulating layer, and positioned between the remaining opposite annular end face and the inner peripheral surface, or a chamfered portion uncovered by the insulating layer and positioned between the remaining opposite annular end face and the inner peripheral surface, such that an intersection between the chamfered portion and the remaining annular end face is located the first radial distance from the inner peripheral surface.
