Product Overview: The NU 2319 Cylindrical Roller Bearing
The NU 2319 Cylindrical Roller Bearing is a high-capacity, single-row bearing designed for heavy-duty industrial applications. With dimensions of 95x200x67mm, this component is part of our robust NU 2300 Series. The 'NU' designation indicates a specific design where the outer ring has two integral flanges and the inner ring is flangeless. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions. Manufactured from high-quality bearing steel, the NU 2319 provides exceptional performance under high radial loads and high speeds.

Key Features of the NU 2319 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides a large contact area, enabling the bearing to support very heavy radial loads.
- Axial Displacement: The NU design allows for free axial movement of the shaft relative to the housing, accommodating thermal expansion or contraction without inducing stress.
- Separable Design: The inner ring is separable from the outer ring and roller assembly, which simplifies mounting, dismounting, and maintenance procedures.
- High-Speed Performance: Engineered with precision cages to manage the rollers effectively, allowing for reliable operation at high rotational speeds.
- Robust Construction: Made from premium, through-hardened bearing steel for superior durability, wear resistance, and a long operational lifespan.
- Low Frictional Profile: Optimized internal geometry minimizes friction between rolling elements and raceways, reducing heat generation and energy consumption.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts in demanding gearbox environments.
- Large Electric Motors: Used as non-locating bearings to support motor shafts and manage thermal growth.
- Pumps and Compressors: Ensures smooth and efficient rotation in various types of industrial pumps and compressors.
- Construction Machinery: Ideal for heavy equipment like excavators, cranes, and earthmovers where high radial loads are common.
- Rolling Mills: Withstands the extreme loads and high temperatures found in steel and metal processing machinery.
- Vibrating Screens and Crushers: Offers the durability needed for machinery in the mining and aggregate industries.
- Wind Turbines: Supports main shafts and gearboxes in wind energy generation systems.
Benefits of Using the NU 2319 Bearing
