Product Overview: The NU 2205 Cylindrical Roller Bearing
The NU 2205 is a high-performance single-row cylindrical roller bearing, engineered to handle heavy radial loads at high speeds. With key dimensions of 25x52x18mm (Bore x Outer Diameter x Thickness), this bearing is a crucial component in a wide array of industrial applications. As part of our NU 2200 Series, the NU 2205 features a unique design where the inner ring is flangeless, while the outer ring has two integral flanges. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion.
Manufactured from high-quality bearing steel, the NU 2205 offers exceptional durability and reliability. Its line contact between the rollers and raceways provides superior radial stiffness and load-carrying capacity compared to ball bearings of the same size.
