High Precision Insulated Bearing 6317-M-J20AA-C3 is Deep Groove Ball Bearing design. its dimension is 85×180×47mm, it has the same dimension and the same design with normal chrome steel 6317 M/C3 bearing. but the most different is 6317-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.
The Coating Process
The plasma spraying process involves generating an arc between two electrodes to ionize a noble gas that is
issued from the plasma torch. The resulting plasma jet is used to carry the injected aluminum oxide powder. This powder is melted by the heat and sprayed at high speed onto the outer or inner ring. When applied in this manner, the oxide layer adheres extremely well to the base material. It is then sealed and ground to size.

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 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).
Type:
Deep groove ball bearing, cylindrical roller bearing
Inner diameter:
50 mm to 110 mm
Dimensional deviation:
Compatible with traditional bearings
Benefits of Electrically 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.
A much more economical solution is to provide for the use of Electrically insulated bearings during the planning stage. This reduces maintenance and repair costs, and increases machine availability – all of which means greater value for the customer.
