Electrically Insulated Cylindrical Roller Bearing NU330 ECM/C4VA301 with Good availability and adequate lead time

Electric Insulated Cylindrical Roller Bearing NU330 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 NU330 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 NU330 ECM/C4 Cylindrical Roller Bearing.

Electrically Insulated Bearing NU330 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.
