Product Overview: The NU 317 Cylindrical Roller Bearing
The NU 317 bearing is a high-performance component within our comprehensive NU 300 Series of Cylindrical Roller Bearings. This single-row cylindrical roller bearing features two integral flanges on the outer ring and no flanges on the inner ring, allowing for axial displacement of the shaft relative to the housing. This design makes the NU 317 ideal as a non-locating bearing, accommodating thermal expansion and contraction without generating internal stresses.
With a bore diameter of 85mm, an outer diameter of 180mm, and a thickness of 41mm, the NU 317 is engineered for demanding industrial applications requiring high radial load capacity and the ability to handle high speeds. Its robust construction ensures reliable and long-lasting performance in a wide range of machinery. As a trusted supplier of industrial bearings and mechanical parts, we ensure that our NU 317 bearings meet rigorous industry standards for precision and durability.
Key Features of the NU 317 Bearing
- High Radial Load Capacity: Designed with a large number of rollers to support significant radial forces, making it suitable for heavy-duty applications.
- Axial Displacement Capability: The NU configuration allows for axial movement between the shaft and housing, preventing internal stresses from thermal expansion or contraction.
- Separable Design: The inner and outer rings, along with the roller and cage assembly, can be mounted separately, simplifying installation and maintenance procedures.
- High-Speed Performance: Engineered for efficient operation even at high rotational speeds, thanks to its low friction characteristics.
- Precision Manufacturing: Produced to strict dimensional tolerances, ensuring accurate alignment and consistent operational stability.
- Durable Construction: Manufactured from high-quality bearing steel for excellent wear resistance and an extended service life in challenging environments.
