High Precision Insulated Bearing 6324-M-J20AA-C3 is Deep Groove Ball Bearing design. its dimension is 120×260×55mm, it has the same dimension and the same design with normal chrome steel 6324-M bearing. but the most different is 6324-M-J20AA-C3 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.


Current-Insulated Bearings as a Preventive Measure · Typical Damage Caused by Electrical Current Passing through the Bearing, the ohmic resistance of the bearing. With higher frequency AC voltage (often encountered in converters!), it depends on the capacitive reactance of the bearing. Basically, a current-insulated bearing acts like a resistor and capacitor connected in parallel. To ensure good insulation, the ohmic resistance should be as high as possible, and the capacitance should be as low as possible.

Insulated bearings provided by EASIER combat electrical erosion in a wide range of conditions, including high humidity.  Sealed  protective  coatings on the outer or inner rings integrate insulating properties into the bearing. They eliminate premature bearing failures  caused  by  stray electric current in applications including:

• Industrial electric motors

• Traction motors

• Generators


Features and Benefits of Coated Bearings

• 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.
