Electrically Insulated Bearings NU315 ECP/C3VL0241 are one kind of Electrically Insulated Cylindrical roller bearing design. NU315 ECP/C3VL0241 also called Caramic Coated Bearings and FAG Current Insulated Bearings, The material are adopt high quality chrome steel, this design are separable. the bearing ring with the rollers and cage assembly can be separated from the other ring, single row cylindrical roller bearings not only NU series design, but also N, NJ, NUP design, this kind of bearing can accommodate axial displacement of the shaft relative to the housing in both directions. the cage we can supply Pressed Steel, Brass cage and nylon cage.
Insulated Bearings can be exposed to electrical current. In a worst-case scenario, this can damage raceways and rolling elements, which, in turn, causes the motor or generator to fail prematurely and without warning.
On top of the extra expenses incurred for repairs, this also means additional costs caused by machine downtime and the resulting production losses.

The plasma spraying process involves generating an arc between two electrodes to ionize a noble gas that is issued from the plasma torch. The resulting plasma jet is used to carry the injected aluminum oxide powder. This powder is melted by the heat and sprayed at high speed onto the outer or inner ring. When applied in this manner, the oxide layer adheres extremely well to the base material. It is then sealed and ground to size.
Product Features of NU315 ECP/C3VL0241 Insulated Bearings
-- High-quality coating
A plasma spray technique is used to apply the aluminum oxide layer. Sophisticated pre- and post- application processes result in an outstanding coating quality.
-- Protective sealant
Insulated bearings are treated with a unique sealant to guard against humidity penetrating the coating and reducing its effectiveness.
-- Optimized solutions
TKW can supply values for relevant electric parameters for the bearings (capacitance, impedance) to optimize the insulating solution for any application.
