NU 314 ECM/C3VL0241 70x150x35 Bearing

The NU 314 ECM/C3VL0241 Single Row Cylindrical Roller Bearing is designed for heavy-duty industrial applications, particularly in machinery that requires high radial load capacity and electrical insulation. Its unique Insocoat insulation coating protects against electrical discharges, making it ideal for use in electric motors, generators, and other electrical machinery.

Suitable Machines:

1. Electric Motors

   • Role: The bearing provides radial support for the rotor, allowing smooth and efficient rotation. The insulation coating prevents electrical currents from flowing through the bearing, avoiding damage caused by arcing.

2. Generators

   • Role: In generators, the bearing ensures stability and smooth rotation under heavy loads while its insulation coating protects the bearing from electrical discharge, extending the life of the machine.

3. Pumps

   • Role: Pumps operate at high speeds and require bearings that can handle substantial radial loads. The NU 314 ECM/C3VL0241 helps in reducing friction and ensuring smooth operation while also preventing electrical damage.

4. Compressors

   • Role: Compressors require bearings that can handle heavy loads and high speeds. This cylindrical roller bearing provides the necessary load-bearing capability and ensures that electrical discharges do not damage the bearing or the surrounding components.

5. Industrial Fans

   • Role: The bearing allows for high-speed, low-friction rotation of industrial fans while ensuring that electrical currents do not pass through the bearing, which could otherwise lead to overheating and bearing failure.

Role of the NU 314 ECM/C3VL0241 in These Machines:

• Radial Load Capacity: The bearing is designed to handle heavy radial loads, making it perfect for high-load machinery like compressors, pumps, and industrial fans.
• Electrical Insulation: The Insocoat insulation coating on the outer ring prevents electrical discharge through the bearing, reducing wear and tear and preventing premature failure in electrical machinery such as motors and generators.
• High-Speed Capability: The bearing is capable of operating at high speeds, with a limiting speed of 5,600 r/min, making it ideal for high-speed applications like fans and compressors.
