Product Overview: The NU 230 Cylindrical Roller Bearing
The NU 230 is a single-row cylindrical roller bearing engineered for superior performance in demanding industrial applications. With principal dimensions of 150x270x45mm, this bearing is a key component in our NU 200 Series, part of the extensive Cylindrical Roller Bearings range. The 'NU' designation signifies a design where the inner ring is free of flanges, and the outer ring has two integral flanges. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured to precision standards, the NU 230 excels at handling very high radial loads at high speeds. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies both installation and maintenance procedures. This feature is particularly advantageous in applications requiring frequent inspections or component changes.
Key Features of the NU 230 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Capability: Accommodates thermal expansion and contraction of the shaft by allowing axial movement in both directions.
- Separable Design: The inner ring is separable, facilitating easier and more efficient mounting and dismounting processes.
- High-Speed Performance: Engineered with low friction characteristics, making it suitable for high-speed rotational applications.
- Robust and Durable: Constructed from high-quality, clean bearing steel to ensure long service life and reliable operation under harsh conditions.
- Component Interchangeability: The separable components can be interchanged, offering flexibility during assembly.
Common Applications of NU 230 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces involved.
- Large Electric Motors: Used as non-locating bearings to support motor shafts and manage thermal expansion.
- Pumps and Compressors: Ensures reliable rotation in heavy-duty fluid and gas handling equipment.
- Construction and Mining Equipment: Withstands the heavy loads and harsh operating environments found in machinery like excavators and crushers.
- Rolling Mills: Essential for supporting the rollers that shape metal in steel and aluminum production.
- Wind Turbines: Used in the gearbox and main shaft assemblies to handle significant loads and rotational speeds.
- Vibrating Screens and Shakers: Its durability is crucial for withstanding the constant vibrations and heavy loads in aggregate and material processing.
Benefits of Using the NU 230 Bearing
