Product Overview: The NU 415 Cylindrical Roller Bearing
The NU 415 bearing is a high-capacity, single-row cylindrical roller bearing designed for heavy-duty industrial applications. With key dimensions of 75x190x45mm, this bearing is a crucial component in our NU 400 Series. Its distinctive NU design features two 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 ideal non-locating bearing for applications where thermal expansion and contraction of the shaft are expected.
As a leading supplier of Cylindrical Roller Bearings, we ensure the NU 415 is manufactured to precise standards. The line contact between the rollers and raceways provides a high radial load-carrying capacity and high stiffness, essential for machinery operating under severe conditions. Its separable design simplifies the mounting and dismounting process, allowing the inner ring to be fitted independently of the outer ring and roller assembly.
Key Features of the NU 415 Bearing
- High Radial Load Capacity: Engineered with line contact between rollers and raceways to support substantial radial forces.
- Axial Displacement Accommodation: The NU design allows free axial movement between the shaft and housing, compensating for thermal expansion.
- Separable Components: The inner ring, outer ring, and roller cage assembly are separable, facilitating easy installation, inspection, and maintenance.
- High Stiffness: The robust construction provides excellent rigidity, ensuring stable shaft support under heavy loads.
- Low Friction Design: Optimized internal geometry minimizes friction and heat generation, enabling higher operational speeds and efficiency.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life.
Common Applications of NU 415 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts in heavy-duty transmission systems.
- Large Electric Motors: Used as non-locating bearings to handle high radial loads and allow for shaft expansion.
- Pumps and Compressors: Ensures smooth and efficient operation in various industrial fluid and gas handling equipment.
