Product Overview: The NUP 309NV Cylindrical Roller Bearing
The NUP 309NV is a high-performance single-row cylindrical roller bearing, engineered to manage substantial radial loads while providing precise axial location for a shaft in both directions. With key dimensions of 45x100x25mm, this bearing is a crucial component in our NUP 300 Series, a part of the broader Cylindrical Roller Bearings family. The NUP design features two integral flanges on the outer ring and a single integral flange plus a loose flange ring on the inner ring. This configuration allows it to function as a locating bearing, fixing the shaft's position axially. The 'NV' suffix typically indicates a polyamide cage, known for its low friction, high-speed capabilities, and resilience.
As a premier supplier of industrial components, we ensure our NUP 309NV bearings are manufactured to rigorous standards, delivering reliability and a long service life. This bearing's unique ability to handle both radial forces and bidirectional axial positioning makes it indispensable in a wide range of demanding industrial applications.
Key Features of the NUP 309NV Bearing
- Bidirectional Axial Location: The unique flange arrangement on the inner and outer rings allows the bearing to locate the shaft axially in both directions.
- High Radial Load Capacity: Designed with line contact between the rollers and raceways, this bearing can support heavy radial loads.
- Separable Design: The inner ring, with its loose flange ring, can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance.
- High-Speed Performance: The polyamide cage (indicated by 'NV') is lightweight and reduces friction, making it suitable for high-speed machinery.
- Durable Construction: Manufactured from high-quality bearing steel to ensure excellent durability and resistance to wear under demanding conditions.
- Precision Engineering: Adheres to strict industry standards for dimensional and running accuracy, ensuring consistent and reliable performance.
Common Applications
