Product Overview: The NU 315 Cylindrical Roller Bearing
The NU 315 is a high-capacity single-row cylindrical roller bearing engineered to handle heavy radial loads at high speeds. With principal dimensions of 75x160x37mm, this bearing is a key component in our NU 300 Series, a part of the broader Cylindrical Roller Bearings collection. The 'NU' designation signifies a design where the inner ring has no flanges, and the outer ring features two integral flanges. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
As a leading supplier of industrial components, we ensure our NU 315 bearings are manufactured to precise industry standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation, inspection, and maintenance procedures. This robust bearing is a reliable choice for demanding industrial applications requiring superior radial support and thermal expansion management.
Key Features of the NU 315 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Accommodates Axial Displacement: The NU design allows for axial movement of the shaft in both directions, compensating for thermal expansion or mounting inaccuracies.
- Separable Design: The inner ring is separable from the outer ring and roller cage assembly, facilitating easy and efficient mounting and dismounting.
- High-Speed Performance: Engineered with an optimized internal geometry to support high rotational speeds with low friction and minimal heat generation.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and a long service life.
- Interchangeability: Produced to standard dimensions, allowing for full interchangeability with other manufacturers' NU 315 bearings.
Common Applications of NU 315 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in power transmission systems.
- Electric Motors and Generators: Used as non-locating bearings on motor shafts to support heavy rotors and manage thermal growth.
- Pumps and Compressors: Ensures reliable rotation of shafts in industrial pumps and compressors operating under demanding conditions.
