Abstract
An insulating device is for a bearing mountable within a housing and includes a generally annular metallic body configured to couple with an outer ring of the bearing so as to be mounted to the bearing when the bearing is separate from a housing. The body includes an axial portion, the axial portion having an inner circumferential surface disposable about the outer ring outer surface and an opposing outer circumferential surface, and first and second radial portions each disposable against a separate one of the outer ring axial ends. At least one oxide layer is formed on at least one of the inner and outer circumferential surfaces of the body axial portion so as to substantially prevent electrical flow between the bearing and the housing.
