Electrically Insulated Bearing 6214-2RSR-J20AA is Deep Groove Ball Bearing design. its dimension is 70×125×24mm, it has the same dimension and the same design with normal chrome steel 6214 bearing. but the most different is 6214M/C4VL0241 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.
Modern traction motor bearings must deliver higher output shaft speeds, the ability to handle shock loads and resist smearing, while controlling component dead weight. In addition, sensitivity to electrical discharge contributes to the unique design challenges in traction motor design.

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 Insulated Bearings
• Oxide ceramic coatings (J20...) provide a high level
of insulation. Plasma spraying is used to apply these coatings to the bearing surfaces (Fig. 5).
• 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.
