NU 1022 M/C3VA3091 110x170x28 Bearing

The NU 1022 M/C3VA3091 bearing is a high-performance cylindrical roller bearing designed for heavy-duty industrial applications. It offers excellent load-carrying capacity, electrical insulation (due to its Insocoat coating), and enhanced durability under extreme conditions. Below are the types of machines this bearing is suitable for:

1. Electric Motors:

   • Role: Supports the rotating shaft, ensuring smooth, low-friction operation while protecting the bearing from electrical erosion with its Insocoat coating. This makes it ideal for motors exposed to electrical currents, enhancing longevity and performance.

2. Gearboxes:

   • Role: Supports the transmission shaft and handles high radial loads, ensuring efficient torque transmission while minimizing wear. Its high load capacity and resistance to thermal expansion make it reliable for prolonged gearbox operation in industrial machinery.

3. Pumps:

   • Role: Provides stable, smooth rotation of the pump shaft, reducing friction and wear under continuous operation. The C3 clearance helps accommodate thermal expansion in high-temperature conditions, improving pump efficiency and lifespan.

4. Compressors:

   • Role: Handles the rotating parts of the compressor, supporting high radial loads and reducing the risk of bearing damage from electrical currents. Its robust design ensures stability and durability in high-speed, high-load environments.

5. Turbines:

   • Role: Ensures smooth, efficient rotation of turbine components under high-speed and high-load conditions. The Insocoat feature protects the bearing from electrical discharge, enhancing reliability and reducing the risk of premature failure.

6. Paper Mills:

   • Role: Provides support for heavy rollers, enabling smooth, continuous operation. Its ability to handle high loads and resist electrical erosion makes it perfect for industrial paper production machinery.

Role of NU 1022 M/C3VA3091 in These Machines:

• High Radial Load Handling: This bearing excels in carrying heavy radial loads, making it perfect for machines like electric motors, gearboxes, and turbines. The cylindrical roller design ensures minimal friction, allowing for efficient operation under continuous heavy loads.

• Electrical Insulation: The Insocoat coating on the outer ring prevents electrical erosion, a common issue in electric motors and generators. This feature ensures longer bearing life in applications where stray currents can cause damage.

• Thermal Expansion Management: The C3 radial internal clearance provides additional space to accommodate thermal expansion, ensuring smooth performance in high-temperature environments like turbines and compressors.
