Product Overview: The NU 2317 Cylindrical Roller Bearing
The NU 2317 is a high-capacity, single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 85x180x60mm, this bearing is a key component in our NU Series, part of the broader Cylindrical Roller Bearings category. The 'NU' designation signifies a design where the inner ring has two integral flanges and the outer ring is flangeless. This configuration is ideal for accommodating axial displacement of the shaft relative to the housing in both directions, making it perfect for applications with thermal expansion or potential mounting inaccuracies.
As a specialist supplier of industrial components, we ensure our NU 2317 bearings meet stringent quality standards. They are designed to handle extremely high radial loads at high speeds, providing exceptional performance and durability. The separable nature of this bearing, where the outer ring can be mounted independently of the inner ring and roller assembly, greatly simplifies both installation and maintenance procedures.

Key Features of the NU 2317 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the support of heavy radial forces.
- Axial Displacement Accommodation: The NU design allows the shaft to move axially in either direction, compensating for thermal expansion and contraction.
- Separable Design: The inner and outer rings can be mounted separately, which simplifies the assembly and maintenance process.
- High-Speed Performance: Engineered with precision geometry to operate efficiently at high rotational speeds with low friction.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for superior wear resistance and extended service life.
- Interchangeability: Produced to standard ISO dimensions, ensuring interchangeability with other manufacturers' bearings.
Common Applications of NU 2317 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial loads common in power transmission.
- Electric Motors and Generators: Used as non-locating bearings to support heavy motor shafts while allowing for axial movement.
- Pumps and Compressors: Ensures reliable operation in industrial fluid handling equipment under continuous, heavy loads.
