Electric Insulated Cylindrical roller Bearing NU217 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 NU217 ECM/C4 Cylindrical roller Bearing.

Electrically Insulated Cylindrical roller bearings NU217 ECM/C4VA301 in which the rolls in roll stands are supported, are subjected to high loads; the specific load is also high. In order that the bearings can reliably support the rolling forces, they must have high load carrying capacity. On the other hand, the mounting space available for these bearings is restricted, especially in relation to the section height of the bearings.

Electrically Insulated NU217 ECM/C4VA301 Cylindrical Roller bearings have a higher load carrying capacity than ball bearings. As a result, the radial forces are supported by roller bearings only, namely cylindrical roller bearings, tapered roller bearings or spherical roller bearings. The material used for the bearing rings and rolling elements is through hardening rolling bearing steel or, in some cases, case hardening steel. The frequent replacement of rolls influences the selection of bearing type.

Electrically Insulated Rolling Bearing NU217 ECM/C4VA301 
 

The Electrically Insulated Cylindrical Roller Bearing NU217 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.
