Product Overview: The N 409 Cylindrical Roller Bearing
The N 409 is a single-row cylindrical roller bearing engineered to handle high radial loads and operate at high speeds. With principal dimensions of 45mm Bore Diameter, 120mm Outer Diameter, and 29mm Thickness, this bearing is a crucial component in heavy-duty industrial applications. As part of our N 400 Series, the N 409 is a member of the broader Cylindrical Roller Bearings family. The 'N' design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it an excellent choice for non-locating bearing positions.
As a leading supplier of industrial components, we ensure our N 409 bearings meet stringent quality standards, delivering reliability and performance. The separable design, where the inner ring can be mounted separately from the outer ring and roller assembly, greatly simplifies installation and maintenance procedures.
Key Features of the N 409 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Accommodation: The flangeless outer ring allows for axial movement of the shaft in both directions, compensating for thermal expansion.
- Separable Design: The inner ring is separable, which facilitates easier mounting, dismounting, and inspection routines.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and a long operational life.
- Dimensional Stability: Precision-engineered to standard dimensions for interchangeability and consistent performance.
