Electrically Insulated Bearings NU215 ECM/C3VL0241 are one kind of Electrically Insulated Cylindrical roller bearing design. NU215 ECM/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 Cylindrical roller bearing NU215 ECM/C3VL0241 is one kind of Current Insulated bearings, it consist of Inner Ring with Coated, or outer ring with coating, brass or nylon, Brass 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.
Product Features of NU215 ECM/C3VL0241 Insulated Bearings
1. High insulation properties
To prevent electric corrosion in bearings, a highly productive aluminum ceramic coating material is used to coat the outer ring, and by combining optimized additives, insulation performance is improved by about tenfold.
2. Improved durability
· Optimizing bearing elements improves film impact resistance by a factor of 3x.
· Optimized ceramic coating materials makes for excellent heat dissipation.
-- 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.
