Application of INSOCOAT bearings 6322 M/C3VL0241
Electrical insulated bearings 6322 M/C3VL0241 can avoid damage caused by electrical corrosion, so they can be used in motors to ensure more reliable operation than ordinary bearings. It is more cost effective and reliable than other insulation methods such as shaft or housing insulation. INSOCOAT bearings have the same dimensions and technical features as non-insulated bearings and are therefore 100% interchangeable. Insulated bearings are suitable for motors and wind power generators,Traction motors of railway vehicles, especially for variable frequency motors.
Operation Precautions of INSOCOAT bearings
To avoid an accident or failure resulting from damage to insulated bearings, carefully observe
the following.
Never drop an insulated bearing or strike it directly with a hammer during installation.
Do not use an insulated bearing if a defect is visible on the surface or it has an unusual appearance.
Attaching an electrical conductor to an insulated bearing can lower the bearing’s insulation resistance.
To prevent current flow from the side faces of a bearing, strictly observe the mounting dimensions given in the dimension tables for required shoulder height.
Providing approximately 15˚ of relief at the entrance to the housing will facilitate assembly.
For DC motors such as those used in railway cars, earth-ground the shaft during a voltage resistance test.
Excessive shock can damage the insulating layer, possibly resulting in electrical pitting. Electrical pitting can in turn damage the bearing, leading to abnormal bearing performance and possible faulty operation or failure.
Size range of INSOCOAT bearings
Electrical insulated deep groove ball bearings
Inner diameter: 40mm ~ 140mm,Outer diameter: 80mm ~ 300mm,Width: 18mm ~ 62mm
Insulated angular contact ball bearings
Inner diameter: 40mm ~ 140mm,Outer diameter: 80mm ~ 300mm,Width size: 18mm ~ 62mm
INSOCOAT cylindrical roller bearings
Inner diameter: 45mm ~ 140mm,Outer diameter size: 100mm ~ 300mm,Width : 25mm ~ 62mm
Feather of electrically insulated bearings
Optimum protection against bearings damage caused by the passage of currents;
More economic than insulation on housings or shaft
Interchangeable: same key dimensions and technical properties as conventional bearings
Coating resistant to damage if correctly handled.
Development status of Insulated bearings
NSK develops insulated bearings for inverter motors used in general industrial machinery
A highly productive aluminum ceramic coating material is sued to coat the outer ring of NSK insulated bearings, and by combining optimized additives, insulation performance is improved by about tenfold.
FAG bearings: current-insulated bearings as a preventive measure to solve typical damage caused by electrical current passing through the bearings
