Electrically insulation bearings For Motors 6314M/C3VL0241 Insocoat ball bearings 6314/C3VL0241

Electrically insulated bearings, called INSOCOAT, are designed to protect a bearing against electric current passage. By inte – grating the insulating properties into the bearing, INSOCOAT bearings can improve reliability and increase machine uptime by virtually eliminating the damaging effect of electrical erosion in applications including:
Industrial electric motors
Traction motors
Generators

The effects of stray electric current :
Electric current passing through the bearing can cause micro-cratering on the raceways of the inner and outer rings and on the roll – ing element surfaces. Heat generated by the electrical discharges causes local melting that creates micro craters and changes in the structure of the metal, which can be recognized as a dull grey discolora – tion of the raceways. If such a bearing continuous to be operated, further a wash – boarding pattern may develop as a secondary damage.
