NU 313 ECM/C3VL0241 65x140x33 Bearing

The NU 313 ECM/C3VL0241 bearing is ideal for a wide range of industrial machines, particularly those requiring high radial load capacity and electrical insulation. It is designed for applications where electrical discharge could damage the bearing, making it suitable for electrically driven machinery.

Suitable Machines:

1. Electric Motors
   • Role: The NU 313 ECM/C3VL0241 provides radial support and ensures smooth rotation in electric motors, while its electrical insulation prevents damage caused by stray electrical currents.
2. Generators
   • Role: In generators, the bearing helps handle the radial load while its insulation prevents electrical arcing, which can prolong the life of the equipment.
3. Compressors
   • Role: In high-speed compressors, this bearing minimizes friction and provides stability for rotating components, making the machine more efficient.
4. Pumps
   • Role: For pumps that operate under heavy loads, the NU 313 ECM/C3VL0241 ensures smooth operation, prevents electrical damage, and maintains stability during prolonged use.
5. Conveyor Systems
   • Role: In conveyor systems, the bearing provides stability for long-lasting and smooth operation, even under heavy loads and high speeds. The electrical insulation helps to avoid electrical damage.
6. Fans and Blowers
   • Role: This bearing allows for high-speed operation, reducing wear and tear on rotating components in fans and blowers while preventing electrical arcing.

Role of the Bearing in These Machines:

The NU 313 ECM/C3VL0241 plays several critical roles in the machines it is used in:

• Radial Load Support: Its cylindrical roller design allows it to handle heavy radial loads, ensuring reliable performance in heavy-duty machinery.
• Electrical Insulation: The VL0241 insulation coating on the outer ring protects the bearing from electrical discharges, preventing damage and ensuring the long-term reliability of equipment like motors and generators.
• Friction Reduction: The bearing minimizes friction, allowing for smoother, more efficient operation of rotating shafts, which in turn improves the overall efficiency of the machine.
• High-Speed Capability: It is designed to operate at high speeds, with a limiting speed of 6,000 r/min, making it suitable for high-performance machines such as compressors, fans, and blowers.
