Product Overview: The NU 224 Cylindrical Roller Bearing
The NU 224 is a high-capacity single-row cylindrical roller bearing, designed with dimensions of 120x215x40mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to handle heavy radial loads at high speeds. The 'NU' designation indicates that it features two integral flanges on the outer ring and a flangeless inner ring. This specific design allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions.
Part of the robust NU 2200 Series, the NU 224 bearing's separable design simplifies mounting and dismounting, as the inner ring can be installed independently of the outer ring and roller assembly. This feature is particularly advantageous for applications requiring an interference fit for both rings. Manufactured from high-quality bearing steel, it provides exceptional durability and reliability in demanding industrial environments.
Features of the NU 224 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the accommodation of very heavy radial loads.
- Axial Displacement: The NU design with a flangeless inner ring permits free axial movement, compensating for shaft expansion or mounting inaccuracies.
- Separable Design: Allows for easy and convenient installation and removal, as the inner ring can be mounted separately from the outer ring assembly.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from premium-grade steel to ensure long service life and consistent performance under challenging conditions.
- Interchangeability: Manufactured to standard dimensions, allowing for easy replacement and interchangeability with other standard bearings.
Applications of NU 224 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the heavy radial forces common in gear systems.
- Electric Motors: Used as non-locating bearings in large electric motors to support the rotor shaft and accommodate thermal expansion.
- Pumps and Compressors: Ensures smooth and efficient operation of rotating components under significant radial stress.
- Construction Machinery: Essential in heavy equipment like excavators, cranes, and loaders where durability and high load capacity are critical.
- Rolling Mills: Withstands the extreme loads and high-speed conditions found in steel and metal processing applications.
- Machine Tool Spindles: Offers the rigidity and precision required for high-performance machine tools.
- Vibrating Screens and Crushers: Its robust design makes it suitable for machinery subjected to heavy vibrations and shock loads.
Benefits of Using the NU 224 Bearing
- Enhanced Machine Reliability: High load capacity and durable construction lead to fewer failures and reduced downtime.
- Extended Service Life: Low-friction operation minimizes wear, resulting in a longer operational lifespan for the bearing and associated components.
- Simplified Maintenance: The separable design facilitates easier inspection, maintenance, and replacement procedures.
- Improved Operational Efficiency: Optimized internal geometry reduces friction, contributing to lower energy consumption and cooler operation.
- Versatile Performance: Effectively handles applications with both high speeds and heavy radial loads, offering a flexible solution for various industries.
- Cost-Effective Solution: Long life and low maintenance requirements translate to a lower total cost of ownership over the machine's lifecycle.
