Electrically Insulated Bearings NU310 ECM/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, NU210 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.

 

Electrically Insulated Cylindrical roller bearing NU310 ECM/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.


Cylindrical Roller Bearings also have the other different design as follows

--Single Row Cylindrical Roller Bearings

--Double Row Cylindrical Roller Bearings

--High Capacity Cylindrical Roller Bearings

--Single Row Full Complement Cylindrical Roller Bearings

--Double Row Full Complement Cylindrical Roller Bearings

 

And different types of cylindrical roller bearings also have their different design according to their feather, and also many kinds of cages, just like Brass cage, Pressed Steel cage, nylon cage etc.


Feature of Cylindrical Roller Bearing

1. The rollers and raceway of inner ring and outer ring are in line contact or repair line contact, this design can make the bearing have large carry capacity. So Cylindrical roller bearing are suitable for heavy load and impact load.

2. Low friction coefficient, suitable for high speed, its limited speed are closed to deep groove ball bearing.

3. N and NU series Cylindrical roller bearing can move in axial direction, so they can accommodate to the changes in the relative position of the shaft and the housing due to thermal expansion or mounting errors.

4. High standard for the machining of shaft or seat holes, Relatively skew for the axial of the outer ring should be control strictly. So the Contact stress concentration can be avoid.

The outer ring and inner ring of Cylindrical Roller Bearing are separatable, the design are easy installation and removal.


Development of concept of insulated bearing


Product Features of NU310 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.
