Electricaly Insulated Cylindrical Roller Bearing NJ2218 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 NJ2218 ECM/C4VA301 consist of one inner ring, one outer ring with Aluminuim Oxide Coating, and one piece of machined brass cage, steel rollers, Its dimension are the same with normal chrome steel NJ2218 ECM/C4 Cylindrical roller Bearing.
Advantages of Electrically Insulated Bearing NJ2218 ECM/C4VA301:
— Higher operational reliability through optimum protection against current passages
— More economical than insulation on housings or shafts
— Interchangeable: Same dimensions and technical properties as conventional bearings
— Coating resistant to mechanical damage if correctly handled
Typical applications:
— Traction motors of railway vehicles
— Electric motors (AC/DC)
— Generators (e.g. in wind turbine generators)
