Electrically Insulated Bearing 6228/C3VL2071 is Deep Groove Ball Bearing design. its dimension is 140×250×42mm, it has the same dimension and the same design with normal chrome steel 6215 M bearing. but the most different is 6228--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.

Development of concept of insulated bearing


The effects of stray electric current Electric current passing through the bearing can cause micro-cratering on the raceways of the inner and outer rings and on the rolling element surfaces. Heat generated by the electrical discharges causes local melting that creates micro craters and changes in the structure of the metal, which can be recognized as a dull grey discoloration of the raceways. If such a bearing continuous to be operated, further a wash boarding pattern may develop as a secondary damage.


Local high temperatures cause the additives in the lubricant to char or burn the base oil. This causes the additives to be consumed more quickly. In the case of grease lubrication, the grease turns black and hard. This signiicantly shortens grease life, leading to shorter bearing service life.


Once bearing damage from electric erosion has progressed, increased noise levels, reduced effectiveness of the lubricant, increased heat and inally excessive vibration can all contribute to signiicantly decreased bearing service life.
