Product Overview: The NU 328 Cylindrical Roller Bearing
The NU 328 is a high-capacity single-row cylindrical roller bearing designed for heavy radial loads and high-speed applications. With principal dimensions of 140mm Bore Diameter, 300mm Outer Diameter, and 62mm Thickness, this bearing is a crucial component in demanding industrial machinery. As part of our NU 300 Series, the NU 328 features two integral flanges on the outer ring and a flangeless inner ring. This design allows it to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing. Its robust construction ensures reliability and a long service life. Explore our full range of Cylindrical Roller Bearings to find the perfect solution for your application.
Key Features of the NU 328 Bearing
- Separable Design: The inner ring can be removed from the outer ring and roller assembly, simplifying mounting and dismounting procedures.
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides a high degree of rigidity and allows the bearing to support heavy radial loads.
- Accommodates Axial Displacement: The NU design allows for free axial movement of the shaft relative to the housing, compensating for thermal expansion and mounting errors.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Manufactured from high-quality bearing steel for exceptional durability and resistance to wear and fatigue.
- Interchangeability: Produced to industry-standard dimensions, ensuring it is interchangeable with other manufacturers' equivalent bearings.
Common Applications of NU 328 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Large Electric Motors: Used as non-locating bearings on motor shafts to support heavy rotors and manage thermal expansion.
- Pumps and Compressors: Ensures reliable operation in heavy-duty pumps where significant radial loads are present.
- Construction and Mining Equipment: Ideal for gear systems and rotating shafts in machinery like excavators, cranes, and conveyors.
- Rolling Mills: Used in the steel and metalworking industries to support the rollers that shape metal under extreme pressure.
- Wind Turbines: Supports the main shaft and gearbox components, providing the necessary capacity for high loads and continuous operation.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed cutting and grinding applications.
Benefits of Using the NU 328 Bearing
