Ceramic Coated Insulating Bearings NU332 ECM/C4VA301 For Prevent Prevent Disrupt Voltage 1000 VDC

Electric Insulated Cylindrical roller Bearing NU332 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 NU332 ECM/C4 Cylindrical roller Bearing.

Feature of Electrically Insulated Cylindrical Roller Bearing NU332 ECM/C4VA301

  1. The rollers and raceway of inner ring and outer ring are in line contact or repair line contact, this design can make the bearing have large carry capacity. So Cylindrical roller bearing are suitable for heavy load and impact load. the outer ring or the inner ring With Aluminium Oxide Coating.
  2. Low friction coefficient, suitable for high speed, its limited speed are closed to deep groove ball bearing.
  3. NU332 ECM/C4VA301 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.
  4. 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 Electrically Insulated Cylindrical Roller Bearing are separatable, the design are easy installation and removal.

Electrically Insulated Rolling Bearing as a Preventive Measure

The Electrically Insulated Cylindrical Roller Bearing NU332 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 NU332 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 NU332-M-J20AA-C4 Bearing, the other type and brand Electrically insulated deep groove ball bearing, insocoat tapered roller bearing, Current-Insulated Bearings.
