Electrically Insulated Bearings NU 1011 ECP/C3VL0241 are one kind of Electrically Insulated Cylindrical roller bearing design. 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, NU 1011 ECP 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.

 

Electrically Insulated Cylindrical roller bearing NU 1011 ECP/C3VL0241 is one kind of Electrically Insulated bearings, it consist of Inner Ring with Coated, or outer ring with coating, brass or nylon, pressed steel cage and steel rollers, the cylindrical roller and raceway of the rings are line contact, so cylindrical roller bearings are the same with spherical roller bearing, tapered roller bearing, thrust roller bearing and the other kinds of roller bearings, they all have larger load capacity than ball bearings, cylindrical roller bearing mainly carry radial load, Small friction between the rollers and the ribs of the rings make the cylindrical roller bearings are suitable for the application which are high speed rotation. There are many different design according to the ribs of the rings, NU, NJ, NUP, N, NF series single row cylindrical roller bearing, Insulated Cylindrical roller bearings focus on used in Electrical Motors.


-- N, NU series cylindrical roller bearing

N series cylindrical roller bearing have no flange on outer ring, and double flange on inner ring. This design Allows displacement of the shaft relative to the bearing housing in both axial directions.

NU series cylindrical roller bearing have flange on both side of the outer ring, and no flange on inner ring, it also allows movement of the shaft relative to the housing in both axial directions, so this design suitable for used as floating bearing.

  

-- NJ, NF Series cylindrical roller bearing

NJ series cylindrical roller bearing have ribs on both side of the outer ring, and single flange on one side of inner ring. It Can withstand a certain degree of one-way axial load .

NF series cylindrical roller bearing have single flange on one side of outer ring, double flange on inner ring , it can carry certain degree of one way axial load. Therefore, this type of structure is suitable for use as a single direction axial locating bearing



Development of concept of insulated bearing


Product Features of NU 1011 ECP/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.
