Product Overview: The NJ 2308 Cylindrical Roller Bearing
The NJ 2308 is a high-capacity single-row cylindrical roller bearing, an essential component within our NJ 2300 Series. Engineered with dimensions of 40x90x33mm, this bearing is designed for applications demanding high radial load support and moderate speeds. Its distinctive 'NJ' configuration features two integral flanges on the outer ring and a single flange on the inner ring, allowing it to locate the shaft axially in one direction. This makes it ideal for securing components against axial movement while accommodating heavy radial forces.
As a key part of our Cylindrical Roller Bearings collection, the NJ 2308 is manufactured to exacting standards from premium-grade steel. Its 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 bearing provides a reliable solution for a wide range of heavy-duty industrial machinery, ensuring smooth and efficient operation.
Features of the NJ 2308 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial loads.
- Single-Direction Axial Location: The flange arrangement enables the bearing to guide and locate a shaft axially in one direction.
- Separable Design: The inner ring is separable, which simplifies mounting, dismounting, and inspection processes.
- Low Friction Operation: Optimized internal geometry minimizes friction and heat generation, leading to enhanced operational efficiency.
- Durable Construction: Manufactured from high-quality, hardened bearing steel for exceptional durability and a long service life.
- High-Speed Suitability: Capable of operating at high rotational speeds, making it versatile for various dynamic applications.
