Electrical insulating bearing

摘要

A bearing (1) is provided with a rolling element (6) interposed between an outer ring (3) and an inner ring (5) thereof. The outer ring (3) of the bearing (1) is formed by integrating three elements of: a metallic outer ring body (11) having a path of rotation of said rolling element (6); an insulating thin film (12), being made of polymer elastic material having an electrical insulating property, and covering a portion where said outer ring body(11) is mounted to a housing (2); and a thin metallic plate (13) provided on an outer surface of the insulating thin film (12).
