Product Overview: The NJ 2204 Cylindrical Roller Bearing
The NJ 2204 is a high-performance single-row cylindrical roller bearing with dimensions of 20x47x18mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to handle high radial loads at high speeds. Its design, part of the versatile NJ Series, features two integral flanges on the inner ring and a single flange on the outer ring. This configuration allows the bearing to provide axial location for a shaft in one direction, making it an excellent choice for applications requiring both robust radial support and precise axial guidance.
Manufactured from premium-grade steel, the NJ 2204 offers exceptional durability and reliability in demanding industrial environments. The line contact between the rollers and raceways minimizes stress concentrations, ensuring a long and predictable service life. Its separable design simplifies both mounting and dismounting, which is a significant advantage during assembly and maintenance operations.
Key Features of the NJ 2204 Bearing
- High Radial Load Capacity: The cylindrical roller design provides a large contact area, enabling it to support heavy radial loads.
- Axial Location in One Direction: Features an 'L-shaped' flange arrangement that guides the shaft axially in a single direction.
- Separable Design: The inner ring with its roller and cage assembly can be mounted independently of the outer ring, facilitating easier installation and maintenance.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, making it suitable for high-speed applications.
- Durable Construction: Made from high-quality, clean bearing steel to ensure longevity and resistance to wear and fatigue.
- Reduced Edge Stresses: The logarithmic profile of the rollers and raceways prevents stress peaks, increasing the bearing's lifespan.
