Product Overview: The NU 2312 Cylindrical Roller Bearing
The NU 2312 is a high-capacity single-row cylindrical roller bearing designed to handle heavy radial loads in demanding industrial applications. With dimensions of 60x130x46mm, this bearing is a key component in our NU 2300 Series. The 'NU' designation signifies that the inner ring features two integral flanges, while the outer ring is flangeless. This unique design 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 2312 offers exceptional durability and performance.

Key Features of the NU 2312 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides a high degree of stiffness and allows the bearing to support heavy radial forces.
- Axial Displacement Accommodation: The flangeless outer ring design permits axial movement, compensating for thermal expansion or mounting inaccuracies between the shaft and housing.
- Separable Design: The inner ring with its roller and cage assembly can be mounted separately from the outer ring, which greatly simplifies installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered with an optimized internal geometry to reduce friction and support high rotational speeds.
- Robust and Durable: Constructed from premium-grade, through-hardened bearing steel for extended service life even under harsh operating conditions.
- Interchangeability: Manufactured to standardized dimensions, ensuring it can be interchanged with other equivalent bearings from different manufacturers.
Common Applications of NU 2312 Bearings
- Industrial Gearboxes: Used as non-locating bearings on gear shafts to support heavy radial loads and allow for thermal expansion.
- Electric Motors: Ideal for the non-locating end of large electric motors, where axial shaft movement must be accommodated.
- Pumps and Compressors: Provides reliable support for rotating shafts in various types of industrial pumps and compressors.
- Construction Machinery: Employed in heavy equipment like excavators, cranes, and loaders where high load capacity and durability are critical.
- Rolling Mills: Suitable for use in steel and metal processing machinery that operates under extreme loads and temperatures.
- Vibrating Screens: Its robust design is well-suited for the demanding environment of vibrating machinery used in mining and aggregate industries.
- Wind Turbines: Utilized in the gearboxes of wind energy systems to handle significant radial forces.
Benefits of Using the NU 2312 Bearing
- Enhanced Machine Reliability: Its high load-carrying capacity prevents premature failure and increases the operational uptime of machinery.
- Simplified Assembly and Maintenance: The separable nature of the bearing allows for easier and faster mounting and dismounting processes.
- Improved Performance: Accommodates shaft expansion and contraction, preventing stress on the bearing and other components, leading to smoother operation.
- Extended Service Life: The durable materials and design that minimizes friction contribute to a longer lifespan for the bearing and the entire assembly.
- Versatile Application Range: Its ability to handle high radial loads and axial displacement makes it suitable for a wide variety of heavy-duty industrial uses. While the NU 2312 allows for free axial movement, it is often paired with an axially locating bearing, such as an NJ 2312, in the same application.
