Product Overview: The NU 324 Cylindrical Roller Bearing
The NU 324 is a high-capacity single row cylindrical roller bearing, featuring the standard dimensions of 120x260x55mm. As a key component in our NU 300 Series, this bearing is engineered to handle heavy radial loads at high speeds. Its distinct NU design features two 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 an excellent choice for non-locating bearing positions. Manufactured from premium-grade steel, the NU 324 is a durable and reliable solution for a wide range of demanding industrial applications.

Key Features of the NU 324 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides a large contact area, enabling the bearing to support very heavy radial loads.
- Axial Displacement Accommodation: The NU design with a flangeless inner ring allows for axial movement, effectively compensating for thermal expansion or contraction of the shaft.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered for low friction, this bearing is suitable for applications requiring high rotational speeds without excessive heat generation.
- Robust Construction: Made from high-quality, hardened bearing steel for exceptional durability and a long service life under tough operating conditions.
- Dimensional Stability: Precision manufacturing ensures consistent dimensions and reliable performance, facilitating easy interchangeability.
Common Applications of NU 324 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used as a non-locating bearing on motor shafts to support heavy rotors while allowing for thermal expansion.
- Pumps and Compressors: Ensures reliable operation of rotating components in various industrial pumps and compressors.
