Electrically Insulated Roller Bearing NU1028 M/C4VA301 Coating Outer Ring for Traction Motors in Railway Applications

Electric Insulated Cylindrical Roller Bearing NU1028 M/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 NU1028 M/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 NU1028 M/C4 Cylindrical roller Bearing.

Electric Insulated Bearing NU1028 M/C4VA301

  • are designed to prevent electric current from passing through the bearing
  • have the external surfaces of either their inner or outer ring coated with an insulating aluminium oxide layer, by applying a sophisticated plasma-spray process for an outstanding quality finish
  • are a very cost-effective solution compared with other insulation methods

Features and Benefits of CoatMaster Electrically Insulated rolling Bearings

The same with normal Cylindrical roller bearing, Electrically Insulated Cylindrical Roller Bearing NU1028 M/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. There are many different design according to the ribs of the rings, NU, NJ, NUP, N, NF series single row cylindrical roller bearing, NNU, NN series double row cylindrical roller bearing.

XRB is the China bearing manufacturer & exporter & supplier, it can supply NU1028 M/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 NU1028-M-J20AA-C4 Bearing, the other type and brand Electrically insulated Cylindrical Roller bearing, insocoat tapered roller bearing, Current-Insulated Bearings.
