Electrically Insulated Bearings NU213 ECM/C3VL0241 are one kind of Electrically Insulated Cylindrical roller bearing design. NU213 ECM/C3VL0241 also called Caramic Coated Bearings or Current insulated Bearings, The material are adopt high quality chrome steel, this design are separable. the bearing ring with the rollers and cage assembly can be separated from the other ring, single row cylindrical roller bearings not only NU series design, but also N, NJ, NUP design, NU213 ECM bearing have two integral flanges on the outer ring and no flanges on the outer ring. this kind of bearing can accommodate axial displacement of the shaft relative to the housing in both directions. The biggest difference is that the outer ring is insulated.

Development of concept of insulated bearing


Product Features of NU213 ECM/C3VL0241 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.


Product Benefits

The new product is designed to improve the reliability of motors in general industrial machinery, thereby contributing to the greater adoption of inverter motors.
