Bearings used in electric motors are susceptible to damage caused by the passage of current. Schaeffler offers a range of innovative solutions to prevent this, including inner and outer rings with oxide ceramic coating and hybrid bearings with ceramic rolling elements. Coated bearings are suitable for breakdown voltages of up to a minimum of 500 V or 1,000 V, depending on the layer thickness. Hybrid bearings with ceramic rolling elements provide even better protection.
