Product Overview: The NUP 308 Cylindrical Roller Bearing
The NUP 308 bearing is a high-performance single-row cylindrical roller bearing engineered for demanding industrial applications. With dimensions of 40x90x23mm (Bore x Outer Diameter x Thickness), this component is a key part of our NUP 300 Series within the broader Cylindrical Roller Bearings collection. The unique '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 the bearing to locate a shaft axially in both directions, making it an excellent choice for applications requiring precise shaft positioning under heavy radial loads.
As a specialist supplier of industrial components, we ensure our NUP 308 bearings are manufactured to rigorous standards, offering exceptional reliability and a long service life. The separable design simplifies mounting and dismounting, which is particularly beneficial during maintenance or assembly of complex machinery. Explore our extensive range of cylindrical roller bearings to find the optimal solution for your mechanical needs.
Features of the NUP 308 Bearing
- Bi-Directional Axial Location: The NUP design securely locates the shaft in both axial directions, preventing movement.
- High Radial Load Capacity: The line contact between rollers and raceways provides high stiffness and accommodates heavy radial loads.
- Separable Design: The inner ring, outer ring, and roller assembly can be mounted separately, simplifying installation and inspection.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, making it suitable for high-speed operation.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for superior wear resistance and longevity.
- Precision Engineering: Adheres to strict industry standards for dimensional and running accuracy, ensuring consistent performance.
