  • Patent number: 9011014
    Abstract: A rolling bearing which can be large-sized, has corrosion resistance, and is allowed to prevent mounting accuracy from deteriorating, a fixing force from decreasing, vibration from occurring at a portion of the rolling bearing to be fixed to a bearing box or the like, and can be used for a long term even in a highly corrosive environment. A rolling bearing (1) has an inner ring (2), an outer ring (3), and rolling elements (4) as bearing members thereof. Of regions of the bearing members which are exposed to a corrosive environment, a film having a sacrificial anode action for a base material of the bearing members is formed in a region including at least a surface (c, d) of the rolling bearing (1) to be fixed. The film formed on the surface (c, d) thereof to be fixed is porous.

  • 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.
