Product Overview: The NUP 310NV Cylindrical Roller Bearing
The NUP 310NV is a high-performance single-row cylindrical roller bearing, a key component in our NUP 300 Series. With principal dimensions of 50mm bore diameter, 110mm outer diameter, and 27mm width, this bearing is engineered for applications requiring high radial load capacity and axial shaft location in both directions. The NUP design features two integral flanges on the outer ring and a single integral flange plus a loose thrust collar on the inner ring. This configuration allows the bearing to act as a locating bearing, effectively fixing the shaft's position against the housing axially.
Manufactured to exacting standards, the NUP 310NV is designed for reliability in demanding industrial environments. Its separable design allows the inner ring to be mounted independently of the outer ring and roller assembly, simplifying installation and maintenance. As a leading supplier of Cylindrical Roller Bearings, we offer a comprehensive range to meet the needs of various machinery and equipment.
Key Features of the NUP 310NV Bearing
- Two-Directional Axial Location: Uniquely designed to locate the shaft axially in both directions, simplifying the overall bearing arrangement.
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Separable Design: The inner ring, outer ring, and roller assembly can be mounted separately, which facilitates easier installation, inspection, and maintenance routines.
- High-Speed Capability: Typically features a robust cage (often polyamide, indicated by 'NV' in some designations) that allows for operation at high rotational speeds.
- Robust Construction: Made from high-quality bearing steel for superior durability, wear resistance, and extended service life.
- Reduced Edge Stresses: The logarithmic profile of the rollers and raceways prevents stress peaks, increasing the bearing's lifespan.
Common Applications of NUP 310NV Bearings
- Industrial Gearboxes: Provides rigid support for gear shafts, ensuring precise meshing and reliable power transmission.
- Electric Motors: Used as locating bearings on motor shafts to handle radial loads and control axial movement.
- Pumps and Compressors: Ensures the stable rotation of impellers and rotors under heavy operational loads.
- Machine Tool Spindles: Delivers the high degree of stiffness and rotational accuracy required for precision machining operations.
