Product Overview: The NU 205 Cylindrical Roller Bearing
The NU 205 bearing is a high-performance single-row cylindrical roller bearing with principal dimensions of 25x52x15mm. As a key component in our Cylindrical Roller Bearings category, it belongs to the versatile NU 200 Series. The 'NU' designation signifies a specific design where the inner ring features two integral flanges and the outer ring is flangeless. 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 in a shaft assembly.
Manufactured to exacting standards from premium bearing steel, the NU 205 is engineered to handle high radial loads at high rotational speeds. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies both installation and maintenance procedures. This bearing is a reliable solution for a wide array of demanding industrial applications requiring robust radial support and axial freedom.
Key Features of the NU 205 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement Accommodation: The NU design permits free axial movement between the shaft and housing, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner ring is detachable from the outer ring and roller cage assembly, facilitating easier mounting and dismounting.
- High-Speed Performance: Engineered with low-friction characteristics, making it suitable for high-speed applications.
- Robust Construction: Made from high-purity, hardened bearing steel for exceptional durability and a long service life.
- Interchangeability: Manufactured to standard ISO dimensions, ensuring it can be easily interchanged with other brands.
