Product Overview: The NU 406 Cylindrical Roller Bearing
The NU 406 is a high-capacity, single-row cylindrical roller bearing designed to handle heavy radial loads at high speeds. As a key component in our NU 400 Series, this bearing is part of the extensive Cylindrical Roller Bearings family. Its defining feature is the NU design, where the inner ring has two integral flanges and the outer ring is flangeless. This configuration allows the bearing to function as a non-locating bearing, accommodating axial displacement of the shaft relative to the housing in both directions. With standard dimensions of 30x90x23mm, the NU 406 is engineered for reliability and precision in demanding industrial applications.
The separable nature of the NU 406, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies both installation and maintenance procedures. This makes it an ideal choice for machinery where frequent assembly and disassembly are required. Our commitment to quality ensures that every NU 406 bearing meets stringent industry standards for performance and durability.
Key Features of the NU 406 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the support of very heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement of the shaft relative to the housing, accommodating thermal expansion or mounting inaccuracies.
- Separable Design: The inner and outer rings can be separated, which simplifies mounting, dismounting, and inspection processes.
- High-Speed Performance: Engineered with low friction characteristics, making it suitable for high-speed rotational applications.
- Robust and Durable: Manufactured from high-grade bearing steel for exceptional hardness, wear resistance, and long service life.
- Non-Locating Functionality: Functions purely as a radial support, allowing it to be paired with a locating bearing for complete shaft guidance.
Common Applications of NU 406 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the heavy radial forces common in gear systems.
- Electric Motors: Used to support motor shafts, ensuring smooth rotation under significant radial loads.
- Pumps and Compressors: Essential for supporting rotating assemblies in industrial fluid and gas handling equipment.
- Machine Tool Spindles: Offers the rigidity and precision required for high-speed machining applications.
- Construction and Mining Equipment: Withstands the harsh conditions and heavy loads found in heavy machinery like excavators and conveyors.
- Rolling Mills: Provides reliable support for rollers in steel and metal processing plants.
- Vibrating Screens and Crushers: Capable of handling the combination of high radial loads and vibrations in aggregate processing machinery.
Benefits of Using the NU 406 Bearing
