Product Overview: The NU 322 Cylindrical Roller Bearing
The NU 322 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. With key dimensions of 110mm Bore Diameter, 240mm Outer Diameter, and 50mm Thickness, this bearing is part of the robust NU 300 Series. Its specific 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 applications with thermal expansion or potential shaft deflection. Manufactured to precise standards, the NU 322 provides exceptional radial load support and is a crucial component in heavy machinery.

Features of the NU 322 Bearing
- High Radial Load Capacity: Engineered with line contact between rollers and raceways to support heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement, preventing stress caused by thermal expansion of the shaft.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance procedures.
- Low Friction Operation: Precision engineering minimizes friction between the rollers and raceway flanges, allowing for higher operational speeds and reduced heat generation.
- Robust Construction: Made from high-quality bearing steel for enhanced durability, wear resistance, and a long service life under tough conditions.
- High Stiffness: Provides a high degree of rigidity, making it suitable for applications requiring precise shaft guidance.
Applications of NU 322 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts in heavy-duty transmission systems.
- Electric Motors: Used in large industrial motors as non-locating bearings to manage shaft expansion.
- Pumps and Compressors: Ensures smooth and efficient operation of rotating components in fluid and gas handling equipment.
- Construction and Mining Machinery: Essential for equipment like excavators, conveyors, and rock crushers that operate under extreme loads.
