Current Insulated Bearing 6316-J20AA-C3 is Deep Groove Ball Bearing design. its dimension is 80×170×39mm, it has the same dimension and the same design with normal chrome steel 6316 bearing. but the most different is 6316-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.


Benefits of Current Insulated Bearing 

• two functions in one solution:

– a bearing function

– electrical insulation

 

• virtually eliminates premature bearing failures caused by stray electric currents

 

• increases machine uptime

• reduces maintenance costs

• provides an economical solution when compared with other insulation solutions

• global availability.

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.

Typical Damage Caused by Electrical Current Passing through the Bearing

Regardless of whether a bearing was exposed to direct current or alternating current (up to frequencies in the MHz range), the resulting changes to the surface are

always the same: Uniformly dull, gray marks in the raceways (Fig. 1) and on the rolling elements. These marks are not very specific and can also be caused by other factors (e. g. lubricating oil containing abrasives).
