Product Overview: The NJ 306 Cylindrical Roller Bearing
The NJ 306 is a high-capacity cylindrical roller bearing with principal dimensions of 30x72x19mm. As a key component in our Cylindrical Roller Bearings range, this bearing belongs to the versatile NJ Series and more specifically the NJ 300 Series. Its design features two integral flanges on the outer ring and a single flange on the inner ring, enabling it to accommodate high radial loads while also locating the shaft axially in one direction. This makes the NJ 306 an excellent choice for applications requiring robust support and precise shaft positioning.
The separable design of the NJ 306, where the inner ring can be mounted separately from the outer ring and roller assembly, greatly simplifies installation and maintenance procedures. Manufactured from high-grade bearing steel, it is engineered for durability and reliable performance in demanding industrial environments. This bearing is essential for machinery that operates under heavy loads and at high speeds, offering a perfect blend of load capacity, rigidity, and axial control.
Features of the NJ 306 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows for the support of heavy radial loads.
- Single-Direction Axial Location: The flange arrangement enables the bearing to fix the shaft's position axially in one direction.
- Separable Design: The inner ring can be removed, which simplifies the mounting and dismounting process.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high-speed applications.
- Robust Construction: Made from premium bearing steel for exceptional durability and long service life.
- Enhanced Rigidity: Provides strong, rigid support for shafts, minimizing deflection under load.
