Product Overview: The NU 2214 Cylindrical Roller Bearing
The NU 2214 is a high-capacity single-row cylindrical roller bearing, engineered to handle heavy radial loads at high speeds. As a key component in our NU 2200 Series, this bearing features a separable design with flanges on the inner ring and a flangeless outer ring. This configuration allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for applications involving thermal expansion or where precise axial positioning is not required. With standard dimensions of 70x125x31mm, the NU 2214 provides a robust and reliable solution for a wide range of industrial machinery.

Features of the NU 2214 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial forces.
- Accommodates Axial Displacement: The NU design allows the shaft to move freely in both axial directions relative to the housing, compensating for thermal expansion.
- Separable Design: The inner ring with its roller and cage assembly can be mounted separately from the outer ring, simplifying installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered with an optimized internal design and cage to operate effectively at high rotational speeds with low friction.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and long service life.
- Interchangeability: Produced to strict industry standards, ensuring dimensional and running accuracy for easy replacement.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts under heavy, continuous radial loads.
- Electric Motors: Commonly used in large electric motors as a non-locating bearing to support the rotor shaft.
- Pumps and Compressors: Ensures smooth and efficient operation in various types of industrial pumps and compressors.
