Electric Insulated Cylindrical Roller Bearing NU314 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 NU314 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 NU314 ECM/C4 Cylindrical roller Bearing.
The same with normal Cylindrical roller bearing, Electrically Insulated Cylindrical Roller Bearing NU314 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 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
Feature of Electrically Insulated Cylindrical Roller Bearing
- VA301 Bearing for traction motors
VL0241 Aluminium oxide coated outside surface of outer ring for electrical resistance up to 1 000ed are closed to deep groove ball bearing. - Electrical Resistance: Voltages up to 3000 V DC
- N and NU series Electrically Insulated Cylindrical roller bearing can move in axial direction, so they can accommodate to the changes in the relative position of the shaft and the housing due to thermal expansion or mounting errors.
- High standard for the machining of shaft or seat holes , Relatively skew for the axial of the outer ring should be control strictly. So the Contact stress concentration can be avoid.
- The outer ring and inner ring of Cylindrical Roller Bearing are separatable , the design are easy installation and removal.
XRB is the China bearing manufacturer & exporter & supplier, it can supply NU314 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 NU314-M-J20AA-C4 Bearing, the other type and brand Electrically insulated Cylindrical Roller bearing, insocoat tapered roller bearing, Current-Insulated Bearings.
