Electrically Insulated Bearings NU1014 ECP/C3VL0241 are one kind of Electrically Insulated Cylindrical roller bearing design. NU1014 ECP/C3VL0241 also called Caramic Coated Bearings or 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, NU1014 ECP bearing have two integral flanges on the outer ring and no flanges on the outer ring. this kind of bearing can accommodate axial displacement of the shaft relative to the housing in both directions. The biggest difference is that the outer ring is insulated.
