High Precision Insulated Bearing 6319/C3VL0241 is Deep Groove Ball Bearing design. its dimension is 95×200×45mm, it has the same dimension and the same design with normal chrome steel 6319 /C3 bearing. but the most different is 6319-C3J20AA bearing with Aluminium Oxide Coating. this insulated can be inner ring coating or outer ring coated. 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.
Coated outer ring
Bearings with an electrically insulating coating on the external surfaces of the outer ring are the most common insulated bearing 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
