To provide a composite type insulator and a conductor assembly for a bearing, which have a fixed conductor.SOLUTION: A composite type electric insulator and a conductor assembly include an annular insulator that can be disposed around a bearing outside ring and is configured to prevent a current flow between an outside ring and a housing, the annular insulator including projecting portions extending in axial direction along a center line and disposed around the center axis at intervals in a circumferential direction. A conductor includes a conductive disc that has an outside diametrical direction end portion that can be engaged with a housing inside surface, an inside diametrical direction end portion defining a center opening portion for receiving a shaft, and an opening portion receiving each of the plurality of projecting portions of the insulator. The disc is fixed in an axial direction with respect to the insulator. An annular conductive brush sub assembly includes a plurality of electric conductive fibers that are united with the conductive disc, and can contact with a shaft outside surface so as to provide a conductive path between the shaft and the disc.SELECTED DRAWING: Figure 2 【課題】固定された導体を有する、軸受のための複合型の絶縁体および導体アセンブリを提供すること。【解決手段】複合型の電気的絶縁体および導体アセンブリは、軸受外側リングの周りに配置可能な、外側リングとハウジングとの間の電流の流れを防止するように構成される環状絶縁体であって、中心線に沿って軸方向に延在しかつ中心線の周りに周方向に間隔を空けて配置される突出部を含む、環状絶縁体を含む。導体は、ハウジング内側表面と係合可能な外側径方向端部と、シャフトを受容するための中央開口部を画成する内側径方向端部と、絶縁体の複数の突出部のうち別個のものをそれぞれ受容する開口部と、を有する導電ディスクを含み、ディスクは、絶縁体に対して軸方向に固定される。環状導電ブラシサブアセンブリは、導電ディスクと結合され、シャフトとディスクとの間に導電経路を提供するようにシャフト外側表面に接触可能な複数の電気的導電繊維を含む。【選択図】図２
