Product Overview: The NUP 311NV Cylindrical Roller Bearing
The NUP 311NV is a high-performance single-row cylindrical roller bearing with dimensions of 55x120x29mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to accommodate heavy radial loads and high speeds. Its unique 'NUP' design features two integral flanges on the outer ring and one integral flange plus a loose flange ring on the inner ring. This configuration allows the bearing to locate the shaft axially in both directions, making it an excellent choice for fixed-end bearing applications.
Manufactured to precise industry standards, the NUP 311NV is part of the versatile NUP 300 Series. Its separable design simplifies the mounting and dismounting process, as the inner ring with the roller and cage assembly can be installed independently of the outer ring. This feature is particularly advantageous in applications requiring a tight interference fit for both rings. Trust in our expertise as a leading supplier of industrial components to provide bearings that enhance the reliability and efficiency of your machinery.
Key Features of the NUP 311NV Bearing
- Bi-Directional Axial Location: Designed to fix the shaft's position in both axial directions, providing excellent stability.
- High Radial Load Capacity: The line contact between rollers and raceways allows for the accommodation of very heavy radial loads.
- Separable Design: The inner and outer rings can be mounted separately, which simplifies installation, inspection, and maintenance routines.
- High-Speed Capability: Engineered for low friction and optimized internal geometry, making it suitable for high-speed operations.
- Robust Construction: Made from high-quality bearing steel for superior durability, wear resistance, and a long service life.
- Precision Engineering: Manufactured with tight tolerances to ensure consistent performance and reliability in demanding industrial environments.
