Electrically Insulated Bearing 6314 M/C4VL0241 Insocoat Bearing 70×150×35mm Used In Electric Motors

Electrically Insulated Bearing 6314 M/C4VL0241 is Deep Groove Ball Bearing design. its dimension is 70×150×35mm, it has the same dimension and the same design with normal chrome steel 6314 bearing. But the most different is 6314M/C4VL0241 bearing with Aluminium Oxide Coating . the coating can Electrical Resistance Voltages up to 3000 V DC.

Electric Insulated bearing has an electrically insulating coat on the outer ring(suffix VL0241) or on the inner ring(suffix VL2071), respectively. insulated bearings are widely used in Electric Motors, Generator, Alternator. there is 100μm thick coating on the surface of the inner or outer ring, the into coat bearing can bear voltages up to 1000V DC, insulated & into coat 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:

• 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 aluminum 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

Electric Insulated Bearing 6314 M/C4VL0241 provide a bearing function and electrical insulation, virtually eliminates premature bearing failure caused by stray electric currents, electrically insulated bearing can reduce the number of failures and improve the machine uptime, reduce the cost of maintenance.
