The ohmic resistance of the bearing. With higher-frequency AC voltage (often encountered in converters!), it depends on the capacitive reactance of the bearing. Basically, a current-insulated bearing acts like a resistor and capacitor connected in parallel. To ensure good
insulation, the ohmic resistance should be as high as possible, and the capacitance should be as low as possible.
Regardless of whether a bearing was exposed to direct current or alternating current (up to frequencies in the MHz range), the resulting changes to the surface are
always the same: Uniformly dull, gray marks in the raceways (Fig. 1) and on the rolling elements. These marks are not very specific and can also be caused by other factors (e. g. lubricating oil containing abrasives).
