Product Overview: The NU 2230 Cylindrical Roller Bearing
The NU 2230 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With key dimensions of 150x270x45mm, this bearing is part of our extensive NU 2200 Series and a core component in our range of Cylindrical Roller Bearings. The 'NU' design features two integral flanges on the outer ring and a flangeless inner ring. This configuration is crucial as it allows for axial displacement of the shaft relative to the housing in both directions, accommodating thermal expansion and preventing axial stress on the bearing.
Manufactured from high-quality bearing steel, the NU 2230 offers exceptional performance under heavy radial loads and high speeds. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies installation, inspection, and maintenance procedures. This makes it an ideal choice for machinery where reliability and serviceability are paramount.
Key Features of the NU 2230 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent support for heavy radial forces.
- Axial Displacement Accommodation: The NU design allows the shaft to move freely in both axial directions relative to the housing.
- Separable Design: The inner ring is separable, facilitating easier and more efficient mounting and dismounting.
- Robust Construction: Made from premium-grade bearing steel for superior durability and resistance to wear and fatigue.
- High-Speed Performance: Engineered with an optimized internal geometry to support high rotational speeds with minimal friction.
- Interchangeability: Manufactured to standard dimensions, ensuring it is interchangeable with other brands.
