High Precision Insulated Bearing 6315/C3VL0241 is Deep Groove Ball Bearing design. its dimension is 75×160×37mm, it has the same dimension and the same design with normal chrome steel 6315 bearing. but the most different is 6315-J20AA 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 can protect the machine to be exposed to electrical current. In a worst-case scenario, this can damage raceways and rolling elements, which in turn, causes the motor or generator to fail prematurely and without warning. On top of the extra expenses incurred for repairs, this also means additional costs caused by machine downtime and the resulting production losses.

Features and Benefits of Coated Bearings 6315/C3VL0241
• Oxide ceramic coatings (J20...) provide a high level
of insulation. Plasma spraying is used to apply these coatings to the bearing surfaces.
• Thanks to a special sealant, the J20AA coating retains its insulating properties even in a damp environment.
The resulting oxide ceramic coating is very hard, wear resistant, and a good thermal conductor.
• The external dimensions of the current-insulated rolling bearings are in accordance with DIN 616
(ISO 15). This means that they are interchangeable with standard bearings.
• For special applications, such as those with a rotating outer ring, we recommend using an inner ring coated with J20C.
• Starting with the 62-series and up, coated deep-groove ball bearings are available in both open and sealed
versions (with lip seals on one or both sides). This
enables the user to also benefit from the advantages offered by for-life lubrication.
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
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
