PURPOSE: An electric insulator device for a bearing is provided to satisfy various electric insulation requirements because the exterior surface is formed out of a metal material. CONSTITUTION: An electric insulator device for a bearing comprises plural metal layers(110), an insulating layer(120), and plural bearings. The insulating layer is formed out of a glass material between the metal layers. The bearings revolve along a rolling surface formed on the external side of the metal layers. The insulating layer includes an outer race which is positioned to surround the bearings. The metal layers and the insulating layer have a ring shape. |
