Product Overview: The NJ 409 Cylindrical Roller Bearing
The NJ 409 is a high-capacity single-row cylindrical roller bearing, expertly designed to handle substantial radial loads while allowing for axial displacement in one direction. With key dimensions of 45x120x29mm (Bore x Outer Diameter x Thickness), this bearing is a crucial component in our NJ Series and the broader Cylindrical Roller Bearings collection. Its unique design features two integral flanges on the inner ring and a single flange on the outer ring. This configuration allows the bearing to locate the shaft axially in a single direction, making it suitable for applications requiring precise shaft guidance under heavy radial stress.
As a leading supplier of industrial components, we ensure our NJ 409 bearings are manufactured for reliability and performance. The separable design, where the outer ring can be mounted independently from the inner ring and roller assembly, simplifies both installation and maintenance procedures, a significant advantage in complex machinery. Explore our complete range of NJ 400 Series bearings to find the ideal solution for your high-performance industrial needs.
Key Features of the NJ 409 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
- Single-Direction Axial Location: Designed to guide and locate a shaft axially in one direction, acting as a one-way locating bearing.
- Separable Design: The inner ring, with its roller and cage assembly, can be mounted separately from the outer ring, simplifying installation and inspection.
- Low-Friction Operation: Optimized internal geometry minimizes friction and heat generation, enabling higher operational speeds and efficiency.
- High Rigidity: The robust construction ensures high stiffness, making it suitable for precision applications like machine tool spindles.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life under demanding conditions.
