Electrically Insulated Bearings 1000VDC

Electrically insulated bearings protect against bearing damage caused by electrocorrosion — the passage of electrical current.
Insulating the bearings with silicon-nitride ceramic eliminates the need for additional electrical insulation at the end covers and provides a minimum 1,000V ac or V dc breakdown voltage. For smaller bearings, silicon-nitride rolling elements can be used. The bearings are available with 35 to 500-mm outerring diameters.
