Product Overview: The NU 222 Cylindrical Roller Bearing
The NU 222 bearing is a high-capacity, single-row cylindrical roller bearing with principal dimensions of 110x200x38mm. As a key component in our NU Series, this bearing is engineered to handle high radial loads at high speeds. Its distinct NU 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 an excellent choice for non-locating bearing positions and applications subject to thermal expansion.
Manufactured from premium-grade bearing steel, the NU 222 ensures durability and reliable performance in demanding industrial environments. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures.

Features of the NU 222 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 with a flangeless inner ring allows for axial movement, compensating for shaft expansion or mounting inaccuracies.
- Separable Design: The inner and outer rings are separable, which simplifies the mounting and dismounting process.
- High-Speed Performance: Engineered with low-friction characteristics, making it suitable for high-speed rotational applications.
- Robust Construction: Made from high-purity, hardened bearing steel for superior wear resistance and extended service life.
- Interchangeable Components: The separable components are often interchangeable with those of other manufacturers, offering flexibility in maintenance.
Applications of NU 222 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 to support motor shafts and accommodate thermal expansion during operation.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps and compressors under heavy loads.
