Product Overview: The NJ 2318 Cylindrical Roller Bearing
The NJ 2318 is a high-capacity single-row cylindrical roller bearing engineered for demanding industrial applications. With principal dimensions of 90mm bore diameter, 190mm outer diameter, and 64mm width, this bearing is part of the robust NJ 2300 Series. Its design features two integral flanges on the outer ring and a single flange on the inner ring, which allows it to accommodate axial displacement of the shaft relative to the housing in one direction, while also providing axial location. This makes it an excellent choice for applications requiring support for heavy radial loads and single-direction axial positioning. As a key component in our Cylindrical Roller Bearings collection, the NJ 2318 is manufactured to precise standards to ensure reliability and a long service life.
Key Features of the NJ 2318 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads and high stiffness.
- Single-Direction Axial Location: The flange arrangement allows the bearing to locate the shaft axially in one direction.
- Separable Design: The inner ring is separable from the outer ring and roller assembly, which simplifies the mounting and dismounting process.
- Low Friction: Engineered with an optimized internal geometry to reduce friction and operational temperature, enhancing efficiency.
- High-Speed Performance: Suitable for applications running at high rotational speeds due to its robust cage and precision manufacturing.
- Durable Construction: Made from high-purity, hardened bearing steel for superior wear resistance and longevity under harsh conditions.
Common Applications
- Industrial Gearboxes: Provides rigid support for gear shafts, handling the high radial forces common in gear systems.
- Pumps and Compressors: Used in heavy-duty pumps where reliable shaft support and axial location are critical.
- Electric Motors: Ideal for larger electric motors that experience significant radial loads.
- Construction Machinery: Found in equipment like excavators, cranes, and rollers where durability is paramount.
- Vibrating Screens and Crushers: Withstands the shock loads and vibrations typical in mining and aggregate processing machinery.
- Rolling Mills: Supports the rollers in steel and metal processing plants, operating under extreme loads and temperatures.
- Wind Turbines: Used in the gearbox and main shaft assemblies of wind power generation systems.
Benefits of Using the NJ 2318 Bearing
- Enhanced Machine Reliability: Its ability to handle heavy loads and provide axial stability reduces stress on other components, minimizing downtime.
- Simplified Installation and Maintenance: The separable design allows for easier handling, inspection, and fitting, reducing maintenance time.
- Extended Service Life: The combination of high load capacity and low friction operation results in a longer operational lifespan for the bearing and the entire assembly.
- Improved Operational Efficiency: Minimized friction leads to lower energy consumption and less heat generation, contributing to more efficient machine performance.
- Versatile Application Range: An effective solution for a wide variety of heavy-duty industrial machinery requiring robust performance.
- Cost-Effective Solution: The long life and low maintenance requirements reduce the total cost of ownership over the machine's lifecycle.
