Product Overview: The NU 418 Cylindrical Roller Bearing
The NU 418 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 90x225x54mm, this bearing is a key component in our Cylindrical Roller Bearings collection and a part of the robust NU 400 Series. Its design features two integral flanges on the inner ring and a flangeless outer ring, which allows it to accommodate axial displacement of the shaft relative to the housing in both directions. This makes the NU 418 a non-locating bearing, ideal for use as a floating bearing in arrangements that must manage thermal expansion.
As a leading supplier of industrial components, we ensure our NU 418 bearings are manufactured to precise standards to deliver exceptional performance in high-radial-load environments. The separable design simplifies mounting and dismounting, which is a significant advantage during installation and maintenance. For comprehensive solutions, explore our entire NU Series of bearings.
Key Features of the NU 418 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: Functions as a non-locating bearing, allowing for thermal expansion and contraction of the shaft without inducing stress.
- Separable Design: The inner ring with its roller and cage assembly can be mounted separately from the outer ring, 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-quality bearing steel for superior durability, wear resistance, and a long service life under tough conditions.
- Low Cross-Sectional Height: Offers a compact design solution for applications where radial space is limited.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces generated during power transmission.
- Large Electric Motors: Used as floating bearings to support motor shafts, accommodating thermal growth during operation.
- Pumps and Compressors: Ensures smooth rotation and stability in heavy-duty fluid handling and gas compression equipment.
- Construction and Mining Machinery: Ideal for use in equipment like excavators, conveyors, and crushers that operate under heavy loads and harsh environments.
- Steel and Paper Mills: Withstands the extreme conditions and high radial loads common in rolling mill and processing line machinery.
- Vibrating Screens and Shakers: The robust design is well-suited for applications involving significant vibration and shock loads.
