Bearing insulation prevents electrical current damage Insulated bearings prevent premature bearing failures eventually caused by stray electrical currents. Insulation properties must remain stable regardless of Electrically Insulated BearingsNKE electrically insulated rolling bearings reliably prevent current discharge. NKE provides bearings with oxide ceramic insulating layers on the bearing
