CoatMaster Eelectrically Insulated Cylindrical Roller Bearing NJ324 ECMC4VA301 Environmentally friendly

Electrical Insulated Cylindrical Roller Bearing NJ324 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 uptime, reduce the cost of maintenance.

Electric Insulated Cylindrical Roller Bearing NJ324 ECM/C4VA301 consist of one inner ring, one outer ring with Aluminuim Oxide Coating, and one piece of machined brass cage, steel balls, Its dimension are the same with normal chrome steel NJ324 ECM/C4 Cylindrical Roller Bearing.

Principle bearing types for traction motor applications

  • Cylindrical roller bearings
  • Electrically insulated CoatMaster cylindrical roller bearings
  • Electrically insulated CoatMaster 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

Loads of Electrically Insulated Rolling Bearing

In order to select the best bearing for a particular application, all operational loads should be taken into account. In addition to the weight of the components, the forces created when power is transmitted, such as those listed below, should also be considered:

  • the magnetic pull resulting from asymmetrical air gaps
  • dynamic forces due to misalignment
  • out of balance forces
  • forces due to pitch errors in gears
  • thrust loads

Loads can be radial, axial or a combination of the two. In cases where there are heavy loads,

Roller bearings are typically used. Ball bearings are generally used for lighter loads. Certain bearings, such as NU322 ECM/C4VA301 cylindrical roller bearings, accommodate radial loads only while other bearings, such as angular contact ball bearings, are better suited for combined loads.
