Electric Insulated Deep Groove Ball Bearing 6215 M/C4VL0241 provide a bearing function and electrical insulation, virtually eliminates premature bearing failure caused by stray electric currents, electrical insulated bearing can reduce the number of failures and improve the machine uptime, reduce the cost of maintenance.

Electric motors Bearing 6215 M/C4VL0241, generators and associated equipment are at risk when an electric current passes through their bearings. This can damage the contact surfaces of rolling elements and raceways in the bearings (electrical erosion) and rapidly degrade the grease. An additional risk in electric motors and generators comes from high frequency currents caused by the inherent stray capacitance. The risk of damage increases where the application uses a frequency converter.

Electric Insulated Bearing 6215 M/C4VL0241/ INSOCOAT bearings:

• are designed to prevent electric current from passing through the bearing
• have the external surfaces of either their inner or outer ring coated with an insulating aluminium oxide layer, by applying a sophisticated plasma-spray process for an outstanding quality finish
• are a very cost-effective solution compared with other insulation methods

 Electrically Insulated Rolling Bearing as a Preventive Measure
 
As a rule, it is very difficult to eliminate the causes of bearing voltages that are induced by the motor. Nevertheless, it is possible to avoid damage to the bearing, if the flow of current can either be prevented or at least significantly reduced. Many types of Electrically Insulated Bearing are available today for this very purpose.

Benefits of CoatMaster 6215 M/C4VL0241 Electrically Insulated Bearing

• two functions in one solution:
  – a bearing function
  – electrical insulation
• virtually eliminates premature bearing failures caused by stray electric currents
• increases machine uptime
• reduces maintenance costs
• provides an economical solution when compared with other insulation solutions
• global availability.
