Product Overview: The NUP 309 Cylindrical Roller Bearing
The NUP 309 is a high-performance single-row cylindrical roller bearing, engineered to handle heavy radial loads and provide precise axial location for shafts in both directions. With principal dimensions of 45mm bore diameter, 100mm outer diameter, and 25mm thickness, this bearing is a robust solution for a wide range of industrial applications. As a key component in our Cylindrical Roller Bearings category, the NUP 309 belongs to the versatile NUP 300 Series. Its unique design features two integral flanges on the outer ring and a single integral flange on the inner ring, with a separate, loose thrust collar. This configuration allows the bearing to function as a locating bearing, fixing the shaft's position relative to the housing axially.
Key Features of the NUP 309 Bearing
- Double-Direction Axial Location: Designed to locate the shaft axially in both directions, providing excellent positional control.
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very high radial forces.
- 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 Capability: Engineered for low friction and optimal roller geometry, making it suitable for applications requiring high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability, wear resistance, and a long service life.
- Rigid and Stable: Provides high stiffness and running accuracy, which is critical in precision machinery like machine tool spindles.
