High Precision Insulated Bearing 6317 M/C3VL0241 is Deep Groove Ball Bearing design. its dimension is 85×180×41mm, it has the same dimension and the same design with normal chrome steel 6317M/C3 bearing. but the most different is 6317-M-C3J20AA bearing with Aluminium Oxide Coating. the coating can Electrical Resistance Voltages up to 3000 V DC. This kind of bearing are widely used in high quality demand application like traction motor.
Electrically Insulated Bearing are not only Electrically Insulated deep groove ball Bearing, but also Electrically Insulated Cylindrical Roller Bearing, Electrically Insulated Tapered Roller Bearing, Electrically Thrust Roller Bearing and the other type Normal or Non-Standard Electrically Insulated Rolling Bearings. they are the same dimension, same cage, same elements and the other data with normal chrome steel rolling bearing, just the different coating on the surface of the inner ring or outer ring of the Rolling Bearing.

Features and Benefits of Coated Bearings 6317 M/C3VL0241
Coated outer ring
Bearings with an electrically insulating coating on the external surfaces of the outer ring are the most common INSOCOAT types. They are:
• Recommended for medium-sized motors using bearing sizes with a bore diameter < 120 mm
• Suitable for all housing types
• Can be applied to bearings with an outside diameter > 80 mm
• Identiied by the sufixes VL0241 and VL0246
Coated inner ring
Bearings with an electrically insulating coating on the external surfaces of the inner ring provide enhanced protection against electric current damage, as the smaller coated surface area offers higher impedance. They are:
• Recommended for larger-sized motors using bearing sizes with a bore diameter > 120 mm
• Can be applied to bearings with a bore diameter > 70 mm
• Identiied by the sufix VL2071 and VL2076
