Electric Insulated Cylindrical Roller Bearing NU318 ECM/C4VL0241 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 NU318 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 NU318 ECM/C4 cylindrical roller bearing. they are all have the enhanced optimized large steel rollers and cage.
Features and Benefits of CoatMaster Electrically Insulated rolling Bearings NU318 ECM/C4VA301
VL0241 : electrically insulating outer ring
- Perfect used for small and medium traction motors
- Its design is based on cylindrical roller bearings and deep groove ball bearings.
- Outer ring is electrically insulated by alumina coating
- Basic elimination of premature bearing failure due to stray currents
VL2071: electrically insulating inner ring
- Perfect used for larger traction motors
- Alumina coating applied to the outer surface of the inner ring: holes, chamfers and end faces
- Improved electrical insulation characteristics compared to coated outer ring design VL0241
- Reduced capacitance due to the small surface area of the coating
- Increased electrical impedance
