Product Overview: The NU 2234 Cylindrical Roller Bearing
The NU 2234 is a high-capacity single-row cylindrical roller bearing designed for heavy-duty industrial applications. With principal dimensions of 170x310x86mm (Bore x Outer Diameter x Thickness), this bearing is a key component in our NU 2200 Series line of Cylindrical Roller Bearings. The 'NU' designation signifies a design with two flanges on the outer ring and no flanges on the inner ring. This unique construction allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions where thermal expansion or contraction of the shaft must be compensated for.
Engineered for superior performance, the NU 2234 excels at handling high radial loads at 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 robust bearing is a reliable solution for machinery operating under demanding conditions.
Key Features of the NU 2234 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement, compensating for shaft expansion and mounting inaccuracies.
- Separable Design: The inner ring is separable, which simplifies the mounting and dismounting process.
- High-Speed Performance: Precision manufacturing ensures low friction and suitability for high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional wear resistance and long service life.
- Interchangeability: Produced to industry-standard dimensions, ensuring it can be interchanged with other manufacturers' equivalent parts.
Common Applications of NU 2234 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts in large-scale transmission systems.
- Rolling Mills: Used in the steel and metal forming industries where extreme loads and high temperatures are common.
