NU 224 120x215x40 Bearing

The NU 224 Single Row Cylindrical Roller Bearing is suitable for a wide range of industrial machines that require high radial load capacity and smooth operation. Below is a list of machines and their specific applications:

1. Electric Motors

   • Role: The bearing provides radial support for the rotating shaft, allowing smooth, low-friction motion and preventing shaft misalignment during high-speed operations.
   • Use Case: Common in large electric motors where high loads are expected, ensuring efficient power generation and minimal wear.

2. Gearboxes

   • Role: The NU 224 bearing supports the gearbox’s rotating shafts, handling heavy radial loads and allowing for axial movement to accommodate thermal expansion.
   • Use Case: Ideal for gearboxes in power transmission systems, providing stability and extending the life of gears and other components.

3. Pumps (Centrifugal and Reciprocating)

   • Role: Supports pump shafts by handling the radial loads generated during operation. The bearing ensures the shafts rotate smoothly under pressure, preventing excessive wear.
   • Use Case: Used in water pumps, oil pumps, and other industrial pumps where efficient rotation and load capacity are essential.

4. Compressors (Screw and Centrifugal Compressors)

   • Role: The bearing stabilizes compressor shafts, handling high radial loads while ensuring smooth motion and preventing shaft misalignment.
   • Use Case: Essential for compressors in HVAC systems, industrial refrigeration units, and air compressors.

5. Turbines (Steam and Gas Turbines)

   • Role: In turbines, the NU 224 bearing supports the turbine shafts, managing heavy radial loads generated during high-speed operations.
   • Use Case: Frequently used in power plants and energy generation systems to ensure reliable turbine operation over long periods.

6. Steel Mills and Paper Mills

   • Role: The bearing supports the heavy rotating components of the mills, handling high radial loads while preventing wear and tear in harsh operating environments.
   • Use Case: Commonly found in rolling mills and paper processing equipment, where stable, high-speed performance is necessary.

Role of NU 224 Bearing in Machines

In all these machines, the NU 224 Single Row Cylindrical Roller Bearing primarily plays the following roles:

• Radial Load Support: The cylindrical rollers in the bearing allow it to handle high radial loads, providing stability in heavy-duty machines.
• Low Friction Operation: The bearing’s design reduces friction between the rotating parts, ensuring smooth motion and extending the lifespan of the machinery.
• Axial Movement Accommodation: The bearing can allow slight axial movement, making it suitable for applications where thermal expansion or shaft elongation is common.
