Product Overview: The NU 2208 Cylindrical Roller Bearing
The NU 2208 is a high-performance single-row cylindrical roller bearing, designed with the dimensions 40x80x23mm. As a key component in our Cylindrical Roller Bearings lineup, it belongs to the versatile NU 2200 Series. This bearing is engineered to handle high radial loads at high speeds. The 'NU' designation signifies that the inner ring is free of flanges, while the outer ring has two integral flanges. This unique construction 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.
Manufactured to stringent industry standards, the NU 2208 features a separable design, which simplifies mounting and dismounting procedures. The inner ring can be mounted separately from the outer ring, roller, and cage assembly, streamlining installation and maintenance. This bearing is a reliable choice for a wide array of demanding industrial applications where strength and precision are paramount.
Key Features of the NU 2208 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Capability: The flangeless inner ring design allows for axial movement of the shaft, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner and outer rings can be separated, simplifying installation, inspection, and maintenance.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, enabling operation at high rotational speeds.
- Enhanced Rigidity: The robust construction offers high stiffness, making it suitable for applications requiring precise shaft guidance.
- Durable Construction: Made from high-grade bearing steel for superior wear resistance and a long operational lifespan.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Pumps and Compressors: Ensures reliable rotation in industrial pumps and compressors where high loads are present.
- Electric Motors: Used as a non-locating bearing in large electric motors to support the rotor shaft.
