CoatMaster Electrically Insulated NJ1026 M/C4VA301 Cylindrical Roller Bearing For Higher Weight of Railway Vehicles

Electric Insulated Cylindrical Roller Bearing NJ1026 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 NJ1026 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 NJ1026 ECM/C4 Cylindrical Roller Bearing.

Electrically Insulated Bearing NJ1026 ECM/C4VA301 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.

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
