Electrically Insulated Rolling Bearing NJ317 ECM/C4VA301 Designation

The Electrically Insulated Cylindrical Roller Bearing NJ317 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.

Feature of Electrically Insulated NJ317 ECM/C4VA301 cylindrical roller bearing

  1. the rollers and raceway are line contact, Large radial load capacity, are Suitable for heavy and impact loads.
  2. Low friction, suitable for high speed, its limited speed closed to deep groove ball bearing
  3. N and NU series can be move on axial direction, they can adapt the change of relatively position between the shaft and housing due to Thermal expansion or mounting error.
  4. High demand of machining for the shaft or the hole of housing, After installation of the bearing, the relatively inclined of the axis of outer ring to be controlled strictly, In order to avoid contact stress concentration.
  5. The Inner or outer ring separable, the design are easy for installation and removal.
