Electric Insulated Deep Groove Ball Bearing 6311 M/C3VL0241 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.

Electrically Insulated Bearing 6311 M/C3VL0241 can be exposed to electrical current. In a worst-case scenario, this can damage raceways and rolling elements, which in turn, causes the motor or generator to fail prematurely and without warning. On top of the extra expenses incurred for repairs, this also means additional costs caused by machine downtime and the resulting production losses

Features and Benefits of XRB Electrically Insulated Ball Bearings

Electric Insulated bearing have an electrically insulating coat on the outer ring (suffix VL0241) or on the inner ring (suffix VL2071) , respectively. Electrically Insulated Bearing  are widely used in Electric Motors , generator , Alternator . there are 100μm thick coating on the surface of inner or outer ring , the insocoat bearing can bear voltages up to 1000V DC , insulated & insocoat bearing can keep away from moisture and humidity , it can carry radial and axial loads in both directions .

Electrically Insulated Rolling Bearing 6311 M/C3VL0241 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.

Electric Insulated Bearing / 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
