Electric Insulated bearing have an electrically insulating coat on the outer ring(suffix VL0241) or on the inner ring(suffix VL2071), respectively. 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.
Electric motors, 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 / INSOCOAT bearings:
Electric Insulated Bearing 6314 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 maintenace.
