Product Overview: The NJ 418 Cylindrical Roller Bearing
The NJ 418 is a high-capacity single-row cylindrical roller bearing with dimensions of 90x190x43mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is specifically engineered to handle substantial radial loads at high speeds. Its design features two integral flanges on the inner ring and a single flange on the outer ring. This configuration allows the bearing to locate the shaft axially in one direction, making it ideal for applications requiring both radial support and single-direction axial positioning. Part of the robust NJ 400 Series, the NJ 418 is manufactured to precise standards, ensuring reliable and efficient performance in demanding industrial environments.
Key Features of the NJ 418 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Single-Direction Axial Location: The flange arrangement allows for the axial positioning of a shaft in one direction.
- Separable Design: The inner ring with the roller and cage assembly can be mounted separately from the outer ring, which simplifies installation, inspection, and maintenance procedures.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, making it suitable for high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for superior wear resistance and extended service life.
- Dimensional Stability: Precision engineering ensures consistent performance and interchangeability.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling high torque and radial forces.
