  • Electrically insulated sleeve bearing and method of making same
    Patent number: 4109978
    Abstract: An electrically insulated bearing and method of making the bearing. In the preferred embodiment the bearing is a sleeve bearing having a tubular member with a machined inner wear surface for supporting the shaft of rotating electrical machinery. The as-cast outer surface of the tubular member is wrapped with an epoxy resin-impregnated fibrous material and covered with a heat-shrinkable tape. The bearing is then subjected to a heat curing cycle. The hardened resin-impregnated fibrous layer is then machined to form the bearing seat and thrust faces.
