Product Overview: The NU 326 Cylindrical Roller Bearing
The NU 326 is a high-capacity single-row cylindrical roller bearing designed for superior performance in demanding industrial applications. With dimensions of 130x280x58mm, this bearing is part of the robust NU Series within our extensive range of Cylindrical Roller Bearings. The NU design features two integral flanges on the outer ring and a smooth, flangeless inner ring. This configuration is crucial as it allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured to precise industry standards, the NU 326 is engineered to handle very high radial loads at high speeds. Its separable design, where the inner ring can be removed from the outer ring and roller assembly, simplifies the mounting and dismounting process, which is a significant advantage during maintenance and installation. This bearing is a vital component in heavy machinery where reliability and durability are paramount.
Features of the NU 326 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the accommodation of heavy radial loads.
- Axial Displacement: The NU design with a flangeless inner ring permits axial movement of the shaft within the bearing, compensating for thermal expansion.
- Separable Design: The inner and outer rings can be mounted separately, which greatly simplifies installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered for low friction and optimized internal geometry, making it suitable for high-speed rotational applications.
- Robust Construction: Made from high-purity, hardened bearing steel for exceptional durability and a long operational service life.
- Interchangeability: Produced with standardized dimensions, allowing for easy replacement and interchangeability with other manufacturers' bearings.
Applications of NU 326 Bearings
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used in large industrial 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.
- Rolling Mills: Withstands the extreme loads and harsh operating conditions found in steel and metal rolling applications.
