NU 224 ECM/C3VL0241 120x215x40 Bearing

The NU 224 ECM/C3VL0241 bearing is designed for heavy-duty industrial applications requiring high radial load capacity and electrical insulation. Below are the types of machines where this bearing is commonly used:

1. Electric Motors:

   • Role: The bearing provides electrical insulation, preventing electrical currents from passing through the bearing and causing damage to both the bearing and the machine. It also supports high radial loads in motors operating under heavy-duty conditions.

2. Generators:

   • Role: In generators, this bearing plays a crucial role by insulating the rotating components from electrical currents while supporting the generator’s rotor shaft under high radial loads.

3. Pumps:

   • Role: The bearing supports the pump shafts, particularly in high-speed and high-load environments, while preventing electrical currents from damaging the rotating components.

4. Industrial Gearboxes:

   • Role: The NU 224 ECM/C3VL0241 handles significant radial loads in gearboxes while maintaining electrical insulation, protecting the gearbox from stray electrical currents that could lead to bearing failure.

5. Compressors:

   • Role: It ensures smooth and reliable operation in compressors by supporting high radial loads and preventing electrical currents from passing through the components, thereby extending the service life of the machinery.

6. Wind Turbines:

   • Role: In wind turbines, this bearing protects against electrical erosion while ensuring that heavy radial loads are efficiently handled in the turbine’s rotating components.

Role in These Machines:

• Electrical Insulation: The NU 224 ECM/C3VL0241 is part of the Insocoat series, featuring a ceramic coating that prevents electrical currents from flowing through the bearing. This protects sensitive equipment, such as motors and generators, from electrical erosion or damage.

• Radial Load Support: The cylindrical roller design allows the bearing to support heavy radial loads in various industrial machines, ensuring efficient and smooth operation even in demanding environments.

• Durability and Longevity: With its machined metal cage and cylindrical design, the bearing is capable of withstanding high loads and speeds, offering durability in critical applications.
