Product Overview: The NU 234 Cylindrical Roller Bearing
The NU 234 is a high-capacity single-row cylindrical roller bearing designed for heavy-duty industrial applications. With principal dimensions of 170x310x52mm, this bearing is part of our robust NU 2300 Series. Its key feature is the NU design, which includes two integral flanges on the outer ring and a flangeless inner ring. This configuration allows the inner ring to move axially relative to the outer ring, accommodating shaft expansion and contraction. The separable design simplifies mounting and dismounting, making it ideal for machinery requiring frequent maintenance. As a crucial component in our Cylindrical Roller Bearings range, the NU 234 is engineered to handle high radial loads at high speeds, ensuring reliability in the most demanding environments.
Key Features of the NU 234 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 axial movement of the shaft relative to the housing, compensating for thermal expansion.
- Separable Design: The inner ring can be mounted independently of the outer ring and roller assembly, simplifying installation and maintenance procedures.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, making it suitable for high-speed operations.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long operational lifespan.
- Interchangeability: Produced to standard ISO dimensions, ensuring it is interchangeable with other manufacturers' equivalent bearings.
Common Applications
- Industrial Gearboxes: Provides rigid support for gears and shafts, handling the high loads and speeds common in gear systems.
- Large Electric Motors: Used as non-locating bearings on motor shafts to support heavy rotors and manage thermal expansion.
- Rolling Mills: Essential in steel and metal processing for supporting the rolls under extreme pressure and temperature.
- Construction and Mining Equipment: Ideal for use in heavy machinery like excavators, crushers, and conveyors where reliability is critical.
- Pumps and Compressors: Ensures smooth and efficient operation of rotating assemblies in heavy-duty industrial pumps.
- Wind Turbines: Utilized in gearbox and main shaft applications to withstand the immense forces generated during power production.
- Vibrating Screens and Shakers: The robust design is well-suited to handle the high radial loads and vibrations found in screening equipment.
