NU 1019 ML/C3VL0241 Bore 95 Mm, INSOCOAT Cylindrical Roller Bearings, Single Row, NU Design
The NU 1019 ML/C3VL0241 INSOCOAT cylindrical roller bearings are widely used in industrial motors (variable frequency motors), railway traction motors, wind turbines, papermaking machinery (exhaust gas recirculation fans), rail transit drive systems, and variable frequency drive equipment—any application where shaft current risks exist.
The NU 1019 ML/C3VL0241 bearing is a INSOCOAT cylindrical roller bearings, single row, NU design with an inner diameter of 95 mm , an outer diameter of 145 mm, a width of 24 mm. It typically uses PN grade precision tolerances and GCr15SiMn rings, GCr15SiMn rolling mlement. Its dynamic radial rated load is approximately 83864 N, its static radial rated load is approximately 109296 N. It uses C3 standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
NU 1019 ML/C3VL0241 bearings ( 95 mm x 145 mm x 24 mm) have the advantages of Insulated against electrolytic corrosion, combining the high radial load capacity and high rigidity of cylindrical roller bearings, and are therefore widely used in the Electric motors, generators, frequency converters, railway traction, machine tools and industrial machinery.

The NU 1019 ML/C3VL0241 INSOCOAT cylindrical roller bearings are primarily composed of an inner ring, outer ring, cylindrical rollers, a cage, and an electrically insulating coating. The outer surfaces of both the inner and outer rings are coated with an approximately 100μm thick alumina coating using a plasma spraying process. The suffix VL0241 indicates a coated outer ring, and VL2071 indicates a coated inner ring. NU-type bearings have flanged outer rings and unflappable inner rings, allowing for bidirectional axial displacement and featuring a separable design.
INSOCOAT cylindrical roller bearings possess excellent electrical insulation properties, effectively preventing current flow and avoiding electro-corrosion damage. They achieve a minimum resistance of 50MΩ at 1000VDC and can withstand voltages up to 3000VDC. They also feature high radial load capacity, low friction, and a long service life, and installation and maintenance are no different from ordinary bearings.
