  • Closure design of a conductive rubber material for allowing current passage through a bearing in electric machines
    Patent number: 8992091
    Abstract: A bearing seal, which has a rubber body impregnated with an electrically conductive material such as graphite. A level of conductivity of the bearing seal depends upon an amount of graphite integrated into the rubber body. A bearing is also disclosed, which includes at least one closure element, such as a seal, arranged between an outer and inner ring of the bearing that is impregnated with an electrically conductive material, such as graphite, to create a conductive pathway for an electrical current to circumvent the rolling elements of the bearing. The closure element aids in ensuring electric current is kept away from the rolling elements by diverting electric current from the outer ring to the inner ring of the bearing.
