Product Overview: The NU 330 Cylindrical Roller Bearing
The NU 330 Cylindrical Roller Bearing is a high-capacity, single-row bearing designed for heavy-duty industrial applications. With principal dimensions of 150mm bore diameter, 320mm outer diameter, and 65mm thickness, this bearing is engineered to handle substantial radial loads at high speeds. As a key component in our Cylindrical Roller Bearings collection, the NU 330 belongs to the versatile NU Series. Its distinctive design features two integral flanges on the outer ring and a flangeless inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions.
Manufactured from premium-grade bearing steel, the NU 330 ensures exceptional durability and performance under demanding operating conditions. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures.
Key Features of the NU 330 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement of the shaft relative to the housing, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner and outer rings can be separated, facilitating easier mounting and dismounting processes.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, enabling reliable operation at high rotational speeds.
- Robust and Durable: Constructed from high-quality, clean steel to extend service life and withstand harsh industrial environments.
- Interchangeability: Manufactured to standardized dimensions, ensuring it is interchangeable with other brands' NU 330 bearings.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces involved.
- Large Electric Motors: Used as non-locating bearings to support motor shafts and manage thermal expansion.
