Electric Insulated Cylindrical Roller Bearing NJ315 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.
Features and Benefits of NJ315 ECM/C4VA301 Electrically Insulated rolling Bearings
The same with normal Cylindrical roller bearing, Electrically Insulated Cylindrical Roller Bearing NJ315 ECM/C4VA301 is one kind of rolling bearing, it consist of Inner Ring, outer ring, cage and steel rollers, the cylindrical roller and raceway of the rings are line contact, so cylindrical roller bearings are the same with spherical roller bearing, tapered roller bearing, thrust roller bearing and the other kinds of roller bearings, they all have larger load capacity than ball bearings, cylindrical roller bearing mainly carry radial load, Small friction between the rollers and the ribs of the rings make the cylindrical roller bearings are suitable for the application which are high speed rotation.

Electrically Insulated Rolling Bearing Designation
The Electrically Insulated Cylindrical Roller Bearing NJ315 ECM/C4VA301 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.
XRB is the China bearing manufacturer & exporter & supplier, it can supply NJ315 ECM/C4VA301 bearing, Our large quantity Electrically insulated Cylindrical Roller Bearing Stock can meet your need with good quality and fast delivery, Also you can find FAG NJ315-M-J20AA-C4 Bearing, the other type and brand Electrically insulated Cylindrical Roller bearing, insocoat tapered roller bearing, Current-Insulated Bearings.
