Insulated Cylindrical Roller Bearing NJ326 ECM/C4VA301 Used In Long Service Intervals For High Speed Trains

Electric Insulated Cylindrical Roller Bearing NJ326 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.

NJ326 ECM/C4VA301 Bearing is special design Rolling Bearing and it official named Electrically Insulated Bearing, Electrically Insulated Bearing are not only Electrically Insulated deep groove ball Bearing, but also Electrically Insulated Cylindrical Roller Bearing, Electrically Insulated Tapered Roller Bearing, Electrically Thrust Roller Bearing and the other type Normal or Non-Standard Electrically Insulated Rolling Bearings. they are the same dimension, same cage, same elements and the other data with normal chrome steel rolling bearing, just the different coating on the surface of the inner ring or outer ring of the 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 of NJ326 ECM/C4VA301 Electrically Insulated Bearing 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 NJ326 ECM/C4VA301 cylindrical roller bearings, accommodate radial loads only while other bearings, such as angular contact ball bearings, are better suited for combined loads.

The Electrically Insulated NJ326 ECM/C4VA301 Cylindrical Roller Bearing adopts the special spraying process, spraying the high quality coating on the outer surface of the bearing, Strong adhesion between film and substrate, Good insulation performance, avoiding the electric corrosion effect of the induced current on the bearing, Prevent current from damage for grease, rolling elements and raceways, Improve the service life of bearings . The process is constantly being improved. Among Electrically Insulated Bearing, there is a 100 μm thick coating on the outer or inner ring surface that can withstand voltages up to 1000 V DC. Special spraying process can form a layer with uniform thickness and strong adhesion , After further processing, it can be protected from moisture and humidity.

Electrically Insulated Bearing can protect the machine to be exposed to electrical current. In a worst-case scenario, this can damage raceways and rolling elements, which in turn, causes the motor or generator to fail prematurely and without warning. On top of the extra expenses incurred for repairs, this also means additional costs caused by machine downtime and the resulting production losses.
