Electric Insulated Cylindrical Roller Bearing NJ314 ECM/C4VA301 provide a bearing function and electrical insulation, virtually eliminates premature bearing failure caused by stray electric currents, electrical insulated bearing can reduce the number of failures and improve the machine up-time, reduce the cost of maintenance.

Electric Insulated Cylindrical roller Bearing NJ314 ECM/C4VA301 consist of one inner ring, one outer ring with Aluminuim Oxide Coating,  Electrically Insulated Cylindrical Roller Bearing can be separately design, its inner ring and outer ring can be interchange of each bearings, the inner ring and outer ring can move relatively to each other in the axial direction. So it can be used as free end bearing, The cylindrical roller bearing, which have double ribs on the side of inner ring or outer ring, and the other side have one single ribs, can hold certain degree of axial load from one direction. this kind bearing usually have pressed steel cage, or the brass cage, some of the application have to adopt Nylon Cage.

Features and Benefits of CoatMaster Electrically Insulated rolling Bearings

The same with normal Cylindrical roller bearing, Electrically Insulated Cylindrical Roller Bearing NJ314 ECM/C4VA301 is one kind of rolling bearing, it consist of Inner Ring, outer ring, 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.

Electrically Insulated Rolling Bearing as a Preventive Measure

The Electrically Insulated Cylindrical Roller Bearing NJ314 ECM/C4VA301 adopts the special spraying process, spraying the high quality coating on the outer surface of the bearing,

Feature of Electrically Insulated 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.
