Product Overview: The NU 2204 Cylindrical Roller Bearing
The NU 2204 is a single-row cylindrical roller bearing from our NU 2200 Series, designed for high performance in demanding industrial applications. With dimensions of 20x47x18mm, this bearing is engineered to handle heavy radial loads at high speeds. Its key feature is the separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifying installation and maintenance. The NU design features two integral flanges on the outer ring and no flanges on the inner ring, allowing it to accommodate axial displacement of the shaft relative to the housing in both directions. This makes it an excellent choice for non-locating bearing positions in machinery. For a comprehensive selection, explore our full range of Cylindrical Roller Bearings.
Key Features of the NU 2204 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial forces.
- Separable Design: The inner ring is separable, facilitating easier mounting, dismounting, and inspection procedures.
- Axial Displacement: Accommodates thermal expansion and contraction of the shaft by allowing free axial movement in either direction.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed applications.
- Robust Construction: Manufactured from high-quality, hardened bearing steel for superior durability and a long service life.
- Interchangeability: Made to industry-standard dimensions, ensuring it can be easily replaced or interchanged with bearings from other manufacturers.
