Features and Benefits of CoatMaster Electrically Insulated rolling Bearings
Dimensions Of NU322 ECM/C4VA301 Electrically Insulated Cylindrical Roller Bearing
In most cases, power output determines shaft size, and shaft size determines the bore diameter of the bearings. In recent years, the tendency has been to use bearings with smaller cross sections because they require less space.
Loads of Electrically Insulated Rolling Bearing
In order to select the best bearing for a particular application, all operational loads should be taken into account. In addition to the weight of the components, the forces created when power is transmitted, such as those listed below, should also be considered:
- the magnetic pull resulting from asymmetrical air gaps
- dynamic forces due to misalignment
- out of balance forces
- forces due to pitch errors in gears
- thrust loads
Loads can be radial, axial or a combination of the two. In cases where there are heavy loads,
roller bearings are typically used. Ball bearings are generally used for lighter loads. Certain bearings, such as NU322 ECM/C4VA301 cylindrical roller bearings, accommodate radial loads only while other bearings, such as angular contact ball bearings, are better suited for combined loads.

The Electrically Insulated NU322 ECM/C4VA301 Cylindrical Roller Bearing 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.
