Insulated Bearings

To support the trend towards electrically motorized wheel drives, bearings have to perform under high temperatures, shocks and vibrations and stray electric currents. SKF hybrid bearings can handle it.SKF hybrid bearings offer OEMs several benefits associated with ceramic rolling elements. Their electrical insulation properties virtually eliminate risk of electrical erosion in the rolling contacts, even under poor lubrication. Low friction and centrifugal forces facilitate high-speed capabilities. End-users ultimately enjoy longer service life and reduced lifecycle costs.Electrical pitting often occurs in bearings used in electrical equipment, such as motors and power generators, as a result of current leakage. An electrical current present near a bearing can flow to the inside of the bearing, causing sparks that damage the rolling contact surface, ultimately leading to bearing failure.
