Product Overview: The NUP 409 Cylindrical Roller Bearing
The NUP 409 is a single-row cylindrical roller bearing engineered for high-performance industrial applications. With key dimensions of 45x100x25mm, this bearing is a crucial component in our NUP 400 Series. 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 positions.
As a key part of our Cylindrical Roller Bearings range, the NUP 409 is designed to handle high radial loads and operate at high speeds. The separable nature of its components—where the inner ring, rollers, and cage assembly can be mounted independently of the outer ring—greatly simplifies installation and maintenance procedures. This bearing is manufactured to precise tolerances, ensuring reliable performance and a long service life in demanding environments.
Key Features of the NUP 409 Bearing
- Bi-Directional Axial Location: The flange arrangement allows for the axial location of the shaft in both directions, providing excellent stability.
- High Radial Load Capacity: The line contact between rollers and raceways provides a high degree of stiffness and is ideal for accommodating heavy radial loads.
- Separable Design: The inner and outer rings can be mounted separately, simplifying the assembly and dismounting process.
- High-Speed Capability: Engineered for low friction and optimal roller geometry, making it suitable for high-speed operations.
- Durable Construction: Manufactured from high-quality, clean bearing steel for superior durability and resistance to wear and fatigue.
- Precision Engineering: Adheres to strict industry standards for dimensional and running accuracy, ensuring consistent and reliable performance.
