Product Overview: The NU 2313 Cylindrical Roller Bearing
The NU 2313 is a high-capacity single-row cylindrical roller bearing, engineered for superior performance in demanding industrial applications. With principal dimensions of 65mm bore diameter, 140mm outer diameter, and 48mm thickness, this bearing is a key component in our NU 2300 Series. Its design is part of the broader Cylindrical Roller Bearings category, known for accommodating heavy radial loads at high speeds. The 'NU' designation signifies that the inner ring has no flanges, allowing for axial displacement of the shaft relative to the housing in both directions. This feature makes the NU 2313 ideal for use as a non-locating bearing, perfectly suited for applications where thermal expansion of the shaft occurs.
Key Features of the NU 2313 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of heavy radial loads.
- Axial Displacement Accommodation: The flangeless inner ring design permits free axial movement, compensating for shaft expansion or mounting inaccuracies.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance procedures.
- Low Friction Operation: Advanced roller and raceway geometry minimizes friction, reducing heat generation and enabling higher operational speeds.
- High Rigidity: The robust construction provides excellent stiffness, ensuring stable and precise shaft support under load.
- Durable Construction: Manufactured from high-quality bearing steel for exceptional hardness, wear resistance, and a long service life.
Common Applications
- Industrial Gearboxes: Provides reliable support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors and Generators: Used as a non-locating bearing on motor shafts to accommodate thermal expansion while supporting heavy rotors.
- Pumps and Compressors: Ensures smooth and efficient operation in various industrial pumps where high radial loads are present.
- Vibrating Machinery: Suitable for use in equipment like vibrating screens and compactors due to its high load capacity and robustness.
