Electrically Insulated Bearings NU210 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.


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

Principle bearing types for traction motor applications

• cylindrical roller bearings

• electrically insulated cylindrical roller bearings

• electrically insulated deep groove ball bearings

• hybrid cylindrical roller bearings with ceramic rollers

• hybrid deep groove ball bearings with ceramic balls

• traction motor bearing units based on cylindrical roller bearings and

deep groove ball bearings

• Sensorised traction motor bearing unit

• Regreasable traction motor bearing unit

Product Features of NU210 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.
