Product Overview: The NJ 2220 Cylindrical Roller Bearing
The NJ 2220 is a high-performance single-row Cylindrical Roller Bearing designed for applications demanding high radial load capacity and moderate axial load support in a single direction. With its principal dimensions of 100x180x46mm (Bore x Outer Diameter x Thickness), this bearing is a robust component engineered for reliability in heavy-duty machinery. As part of our NJ 2200 Series, the NJ 2220 features two integral flanges on the inner ring and a single flange on the outer ring, allowing it to locate the shaft axially in one direction.
The separable design of the NJ 2220, where the inner ring with the roller and cage assembly can be mounted independently of the outer ring, greatly simplifies both installation and maintenance procedures. This feature is particularly advantageous in applications where access is limited. Manufactured from high-quality bearing steel, this component ensures durability and a long service life even under strenuous operating conditions, making it an essential part for various industrial sectors.
Features of the NJ 2220 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 configuration allows the bearing to accommodate axial loads and locate the shaft in one direction.
- Separable Design: The inner and outer rings can be mounted separately, which simplifies the assembly and dismounting process.
- High Rigidity: Engineered for high stiffness, making it suitable for applications requiring precise shaft guidance.
- Low Friction Operation: Optimized internal geometry reduces friction and heat generation, leading to improved efficiency and longer service life.
- Durable Construction: Made from premium-grade, through-hardened bearing steel for maximum wear resistance and longevity.
Applications of NJ 2220 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high loads typical in power transmission systems.
- Electric Motors: Used in large electric motors to support the rotor shaft and manage radial forces.
- Pumps and Compressors: Ensures reliable operation of rotating components in fluid and gas handling equipment.
- Rolling Mills: Capable of withstanding the extreme loads and harsh conditions found in steel and metal processing.
- Construction and Mining Equipment: Ideal for heavy machinery like excavators, crushers, and conveyors.
- Wind Turbines: Used in the gearboxes of wind energy systems to handle significant and fluctuating loads.
- Vibrating Screens and Shakers: The bearing's robust design is well-suited for high-vibration industrial applications.
Benefits of Using the NJ 2220 Bearing
- Enhanced Machine Reliability: Its high load-carrying capacity and robust design contribute to fewer breakdowns and more consistent performance.
- Simplified Maintenance and Installation: The separable nature of the bearing allows for easier inspection, replacement, and fitting.
- Improved Operational Efficiency: Low-friction characteristics help reduce energy consumption and operating temperatures.
- Extended Service Life: High-quality materials and precision manufacturing minimize wear, leading to a longer operational lifespan for the bearing and associated machinery.
- Versatile Shaft Support: Combines radial support with axial location, potentially simplifying the overall bearing arrangement in a machine.
- Cost-Effective Solution: Offers a durable and reliable performance that reduces the total cost of ownership through lower maintenance needs and longer life. A comparable alternative for pure radial load is the NU 2220.
