Product Overview: The NU 2318 Cylindrical Roller Bearing
The NU 2318 is a high-capacity single-row cylindrical roller bearing, engineered to handle heavy radial loads at high speeds. With key dimensions of 90mm bore diameter, 190mm outer diameter, and 64mm width, this bearing is a robust component in our Cylindrical Roller Bearings collection. Part of the NU 2300 Series, its design features two integral flanges on the inner ring and a flangeless outer ring. This 'NU' configuration allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing to accommodate thermal expansion or mounting inaccuracies.
As a leading supplier of industrial components, we ensure our NU 2318 bearings are manufactured to the highest standards, offering exceptional reliability and service life. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation and maintenance procedures, reducing machinery downtime.
Key Features of the NU 2318 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial forces.
- Axial Displacement Accommodation: The NU design allows the shaft to move axially in either direction, compensating for thermal expansion and contraction.
- Separable Design: The inner ring is separable, facilitating easier mounting, dismounting, and inspection processes.
- High-Speed Performance: Engineered with an optimized internal geometry to support high rotational speeds with low friction and heat generation.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for superior durability and resistance to wear and fatigue.
- Interchangeability: Produced to standard ISO dimensions, ensuring it is interchangeable with other manufacturers' equivalent parts.
Common Applications
- Industrial Gearboxes: Provides strong radial support for gears and shafts in heavy-duty transmission systems.
- Pumps and Compressors: Used in industrial pumps where reliable operation under high radial stress is essential.
- Electric Motors: Ideal for large electric motors, supporting the rotor shaft and handling significant radial loads.
- Construction Machinery: Found in heavy equipment like excavators, loaders, and cranes where durability is critical.
- Rolling Mills: Withstands the extreme radial forces present in steel and metal rolling applications.
- Mining and Quarrying Equipment: Offers reliable performance in crushers, conveyors, and screening machinery.
- Wind Turbines: Used in the gearbox and main shaft assemblies of wind power generation systems.
