Product Overview: The NU 203 Cylindrical Roller Bearing
The NU 203 bearing is a high-capacity cylindrical roller bearing with principal dimensions of 17x40x12mm. As part of our NU 200 Series, this bearing is engineered to handle high radial loads at high speeds. Its distinct 'NU' design features two flanges on the outer ring and no flanges on the inner 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 applications with thermal expansion or potential mounting inaccuracies. Manufactured from high-quality bearing steel, the NU 203 ensures reliability and a long service life in demanding industrial environments.

Features of the NU 203 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The non-flanged inner ring allows for axial movement, compensating for shaft expansion and contraction.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, which simplifies installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed applications.
- Robust Construction: Made from premium, through-hardened bearing steel for exceptional durability and wear resistance.
- Precision Engineering: Manufactured to tight tolerances to ensure consistent performance and dimensional stability.
