Product Overview: The NU 317 Cylindrical Roller Bearing
The NU 317 is a single-row cylindrical roller bearing, a robust component from our NU 300 Series, designed for applications demanding high radial load capacity and high-speed performance. With dimensions of 85x180x41mm, this bearing is a crucial part of our extensive range of Cylindrical Roller Bearings. Its distinctive 'NU' design features two integral flanges on the outer ring and a flangeless inner ring. 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 precise industry standards, the NU 317 ensures exceptional reliability and a long service life in heavy-duty industrial machinery. The separable design, where the inner ring can be mounted independently from the outer ring and roller assembly, simplifies both installation and maintenance procedures.
Key Features of the NU 317 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement of the shaft relative to the housing, compensating for thermal expansion.
- Separable Design: The inner ring is separable, facilitating easier mounting, dismounting, and inspection.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from high-grade bearing steel for superior durability, wear resistance, and operational longevity.
- High Stiffness: Provides rigid support for shafts, minimizing deflection under heavy loads.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used as non-locating bearings on motor shafts to support radial loads while allowing for thermal expansion.
- Pumps and Compressors: Ensures smooth and efficient operation of rotating components in various types of pumps.
- Construction Machinery: Employed in heavy equipment like excavators and cranes where durability is critical.
- Rolling Mills: Withstands the extreme loads and high temperatures found in metal rolling applications.
- Vibrating Screens and Crushers: Offers the necessary durability to perform in harsh, high-vibration environments.
- Wind Turbines: Used in gearbox and main shaft applications to handle significant radial forces.
