Product Overview: The NJ 208 Cylindrical Roller Bearing
The NJ 208 is a high-performance, single-row cylindrical roller bearing designed to handle heavy radial loads and high-speed applications. As a key component in our Cylindrical Roller Bearings category, this bearing is part of the versatile NJ 200 Series. Its specific design features two integral flanges on the outer ring and a single flange on the inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in one direction, while also providing axial location for the shaft in the other direction. With standard dimensions of 40mm bore diameter, 80mm outer diameter, and 18mm thickness, the NJ 208 is a reliable choice for a wide array of industrial machinery.
Features of the NJ 208 Bearing
- NJ Type Design: Features two flanges on the outer ring and one on the inner ring, enabling single-direction axial location.
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial forces.
- Separable Components: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and maintenance.
- High-Speed Performance: Engineered with optimized internal geometry to reduce friction and support high rotational speeds.
- Durable Construction: Manufactured from high-quality bearing steel for enhanced durability and a long operational lifespan.
- Axial Displacement Accommodation: Allows for thermal expansion or minor misalignment of the shaft in one axial direction.
