Product Overview: The NU 312 Cylindrical Roller Bearing
The NU 312 is a high-capacity single-row cylindrical roller bearing with principal dimensions of 60x130x31mm. As a key component in our NU 300 Series, this bearing is part of the broader Cylindrical Roller Bearings category. The 'NU' designation signifies a design where the inner ring has two integral flanges, and the outer 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 ideal choice for non-locating bearing positions in demanding industrial applications.
Engineered for high performance, the NU 312 bearing is designed to handle very high radial loads at high speeds. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation and maintenance procedures. This feature is particularly beneficial in applications requiring frequent assembly and disassembly. Trust our expertise as a premier supplier of industrial parts to provide reliable components like the NU 312 for your most critical machinery.
Key Features of the NU 312 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the accommodation of heavy radial loads.
- Axial Displacement: The flangeless outer ring 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 easier mounting, dismounting, and inspection.
- High-Speed Capability: Optimized internal geometry and surface finish reduce friction, enabling operation at high rotational speeds.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and a long service life.
- Interchangeability: Produced to strict ISO standards, ensuring dimensional and running accuracy for global interchangeability.
