Product Overview: The NJ 419 Cylindrical Roller Bearing
The NJ 419 is a high-capacity single-row cylindrical roller bearing designed for heavy-duty industrial applications. With dimensions of 95x240x55mm, this bearing is engineered to handle substantial radial loads while also providing axial location for the shaft in one direction. As a key component in our Cylindrical Roller Bearings collection, the NJ 419 is part of the robust NJ 400 Series. Its design features two integral flanges on the inner ring and one on the outer ring, making it ideal for applications where thermal expansion of the shaft must be accommodated. The separable nature of this bearing, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies installation and maintenance procedures.
Key Features of the NJ 419 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows for the support of very high radial forces.
- Single-Direction Axial Location: The flange arrangement enables the bearing to locate the shaft axially in one direction, acting as a locating bearing.
- Separable Design: The inner ring can be removed, which facilitates easier mounting, dismounting, and inspection.
- Low Friction: Engineered for minimal friction, ensuring smooth operation, reduced heat generation, and enhanced efficiency.
- Durable Construction: Manufactured from high-quality, clean bearing steel for exceptional durability and a long service life under demanding conditions.
- High-Speed Performance: The cage design and roller geometry are optimized for operation at high rotational speeds.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, ensuring reliable power transmission.
- Pumps and Compressors: Used in heavy-duty pumps where high radial loads are a primary concern.
- Electric Motors: Supports motor shafts, especially in large industrial motors that operate under significant loads.
- Construction Machinery: Essential in equipment like excavators, cranes, and road rollers for supporting rotating components.
- Rolling Mills: Withstands the extreme forces and high temperatures found in steel and metal processing.
- Vibrating Screens and Crushers: Ideal for mining and aggregate machinery due to its ability to handle heavy loads and vibrations.
- Wind Turbines: Used in the gearbox and main shaft assemblies to support immense operational forces.
Benefits of Using the NJ 419 Bearing
