Product Overview: The NU 314 Cylindrical Roller Bearing
The NU 314 Cylindrical Roller Bearing is a high-capacity, single-row bearing engineered to handle heavy radial loads at high speeds. With dimensions of 70x150x35mm, this bearing is a key component in our NU 300 Series. The 'NU' designation signifies a design where the inner ring has no flanges, and the outer ring has two integral flanges. This unique configuration allows the shaft to move axially in either direction relative to the housing, making it an excellent choice for non-locating bearing positions, especially where thermal expansion of the shaft occurs. As a leading supplier, we ensure our NU 314 bearings provide the reliability and performance needed for demanding industrial applications.
Key Features of the NU 314 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides a high capacity for radial forces.
- Axial Displacement: The flangeless inner ring design allows for axial displacement of the shaft, compensating for thermal expansion and mounting errors.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered for low friction and minimal heat generation, enabling reliable operation at high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life under tough conditions.
- Precision Engineering: Adheres to strict industry standards for dimensional and running accuracy, ensuring consistent and reliable performance.
Common Applications of NU 314 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, accommodating heavy radial loads.
- Electric Motors: Used as non-locating bearings on motor shafts to allow for thermal expansion.
- Pumps and Compressors: Ensures reliable rotation of shafts in various industrial pump and compressor systems.
- Construction Machinery: Found in heavy equipment like excavators and cranes where high radial loads are common.
- Rolling Mills: Withstands the extreme radial forces present in steel and metal processing machinery.
- Vibrating Screens: Suitable for shaker screens and other vibrating equipment due to its robust design.
- Machine Tool Spindles: Offers the precision and rigidity required for high-performance machine tools.
Benefits of Using the NU 314 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy radial loads and axial movement reduces stress on the entire assembly, minimizing downtime.
- Extended Service Life: The low-friction design and robust materials contribute to a longer operational life, even in continuous-use applications.
- Simplified Maintenance: The separable components make it easier to install, remove, and inspect the bearing, reducing maintenance time and costs.
- Improved Operational Efficiency: Minimizes energy loss through friction, contributing to more efficient machinery operation.
- Versatile Functionality: Ideal as a non-locating or 'floating' bearing, providing flexibility in machine design.
- Accommodates Misalignment: While primarily for radial loads, it effectively manages axial shaft movement caused by thermal effects or minor alignment issues.
