Electrically Insulated Bearing 6328/C3VL2071 is Deep Groove Ball Bearing design. its dimension is 140×300×62mm, it has the same dimension and the same design with normal chrome steel 6328/C3 bearing. but the most different is 6328--J2AA-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.
Features of insulated bearings
1. High insulation properties
To prevent electric corrosion in bearings, a highly productive aluminum ceramic coating material is used to coat the outer ring, and by combining optimized additives, insulation performance is improved by about tenfold.
2. Improved durability
· Optimizing bearing elements improves film impact resistance by a factor of 3x.
· Optimized ceramic coating materials makes for excellent heat dissipation.

A cost-effective solution
Electrically Insulated bearings are a very cost effective solution for protecting bearings against damage or failure due to passage of electric current through the rolling contacts.
The total cost of Electrically Insulated bearings is lower than shaft or housing insulation.
Beneits:
• Two functions in one solution – a bearing function – electrical insulation
• Virtually eliminates premature bearing failures caused by stray electric currents
• Increased machine uptime
• Reduced maintenance costs
• Provide an economical solution when compared with other insulation solutions
• Global availability of a wide assortment
• Easy mounting and ready to use solutions
