Product Overview: The NU 204 Cylindrical Roller Bearing
The NU 204 is a single-row cylindrical roller bearing, a key component in our Cylindrical Roller Bearings category and a part of the versatile NU 200 Series. With dimensions of 20x47x14mm, this bearing is engineered to handle high radial loads at high speeds. Its distinctive NU design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions.
As a specialist supplier of industrial components, we ensure our NU 204 bearings are manufactured to the highest industry standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies the installation and maintenance process. This makes the NU 204 an indispensable part for a wide range of industrial machinery demanding reliability and precision.
Key Features of the NU 204 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial loads.
- Axial Displacement: The NU design permits free axial movement of the shaft relative to the housing, compensating for thermal expansion.
- Separable Design: The inner ring, outer ring, and roller assembly are separable, facilitating easier mounting and dismounting.
- High-Speed Performance: Engineered for low friction and optimized internal geometry, making it suitable for high-speed applications.
- Robust Construction: Manufactured from high-quality bearing steel with a durable cage for long service life and reliability.
- Precision Engineering: Adheres to strict dimensional and running accuracy standards for consistent and efficient operation.
Common Applications of NU 204 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used as non-locating bearings on motor shafts to support radial loads while allowing for thermal expansion.
- Pumps and Compressors: Ensures smooth rotation of shafts in demanding fluid and gas handling equipment.
- Machine Tool Spindles: Offers the rigidity and precision required for high-accuracy machining operations.
