Product Overview: The NJ 2208 Cylindrical Roller Bearing
The NJ 2208 is a high-performance single-row cylindrical roller bearing with principal dimensions of 40x80x23mm. As a key component in our Cylindrical Roller Bearings category, it belongs to the versatile NJ Series and the robust NJ 2200 Series. The NJ design is characterized by two integral flanges on the outer ring and a single integral flange on the inner ring. This configuration allows the bearing to accommodate high radial loads and locate the shaft axially in one direction, making it an excellent choice for applications requiring precise shaft guidance.
Manufactured to exacting industry standards, the NJ 2208 bearing features a separable design, where the inner ring can be mounted independently of the outer ring and roller assembly. This simplifies installation, inspection, and maintenance procedures. Its robust construction and low-friction characteristics ensure reliable performance and a long service life, even in high-speed and demanding industrial environments.
Key Features of the NJ 2208 Bearing
- High Radial Load Capacity: Engineered with line contact between rollers and raceways to support heavy radial forces.
- Single-Direction Axial Location: The flange arrangement provides precise axial positioning for the shaft in one direction.
- Separable Design: The inner ring can be dismounted, facilitating easier mounting and maintenance operations.
