Product Overview: The NJ 308 Cylindrical Roller Bearing
The NJ 308 Cylindrical Roller Bearing is a high-capacity component engineered to manage significant radial loads and locate the shaft axially in a single direction. With principal dimensions of 40mm bore diameter, 90mm outer diameter, and 23mm thickness, this bearing is a robust choice for demanding industrial applications. As a key part of our NJ Series, the NJ 308 features two integral flanges on the outer ring and a single flange on the inner ring. This design allows it to accommodate axial displacement of the shaft relative to the housing in one direction, making it an excellent shaft-locating bearing.
As a premier supplier of Cylindrical Roller Bearings and other mechanical parts, we ensure our NJ 308 bearings are manufactured to the highest industry standards. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies both installation and maintenance procedures. This makes it a practical and reliable solution for a wide variety of heavy-duty machinery.
Key Features of the NJ 308 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways allows for the accommodation of very high radial forces.
- Axial Location in One Direction: The single flange on the inner ring enables the bearing to guide and locate the shaft axially in one direction.
- Separable Design: The inner ring is detachable from the outer ring and roller cage assembly, facilitating easy mounting and dismounting.
- High-Speed Performance: Engineered with low friction characteristics, making it suitable for applications with high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life under tough conditions.
- Enhanced Rigidity: Provides a high degree of stiffness, which is crucial for applications requiring precise shaft support.
