Product Overview: The NJ 2228 Cylindrical Roller Bearing
The NJ 2228 is a high-capacity single-row cylindrical roller bearing engineered for demanding industrial applications. With principal dimensions of 140mm bore diameter, 250mm outer diameter, and 68mm thickness, this bearing is part of our robust NJ 2200 Series. Its distinctive design features two integral flanges on the inner ring and one on the outer ring, allowing it to provide axial location for a shaft in a single direction. This makes it an excellent choice for applications requiring both high radial load support and precise one-way shaft positioning.
As a leading supplier of Cylindrical Roller Bearings, we ensure our NJ 2228 bearings are manufactured to the highest industry standards. The separable design, where the outer ring can be mounted independently from the inner ring and roller assembly, simplifies both installation and maintenance procedures, particularly in confined spaces. This bearing is a critical component in heavy machinery, ensuring reliability and extending operational life.
Key Features of the NJ 2228 Bearing
- Single-Direction Axial Location: The flange configuration securely locates the shaft axially in one direction.
- High Radial Load Capacity: Designed with line contact between the rollers and raceways, enabling it to support heavy radial loads.
- Separable Design: The inner and outer rings can be mounted separately, simplifying assembly and maintenance.
- High-Speed Capability: Low-friction design is suitable for applications involving high rotational speeds.
- Durable Construction: Manufactured from high-quality bearing steel for enhanced strength, wear resistance, and service life.
- Accommodates Axial Displacement: Allows for some axial displacement of the shaft relative to the housing in the opposite direction of the locating flange.
Common Applications of NJ 2228 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling significant radial forces.
- Electric Motors and Generators: Used in large motors to support rotor shafts and manage loads effectively.
- Pumps and Compressors: Ensures the stable rotation of impellers and crankshafts under heavy operational stress.
- Construction and Mining Equipment: Ideal for use in heavy machinery like excavators, loaders, and crushing equipment.
- Rolling Mills: Supports the rollers used in metal forming and processing applications.
- Wind Turbines: Utilized in gearbox and main shaft applications to handle the immense forces involved.
- Material Handling Systems: Essential for heavy-duty conveyor rollers and lifting equipment.
Benefits of Using the NJ 2228 Bearing
- Enhanced Machine Reliability: Provides stable and precise shaft support, reducing the risk of component failure.
- Simplified Installation and Maintenance: The separable nature of the bearing allows for easier mounting and dismounting, reducing downtime.
- Extended Service Life: High load capacity and durable materials result in a longer operational lifespan, even in harsh conditions.
- Improved Operational Efficiency: Low friction characteristics contribute to smoother operation and reduced energy consumption.
- Versatile Shaft Support: Combines high radial support with the ability to manage axial loads in one direction, offering a versatile solution.
- Reduced Wear and Tear: Proper axial location prevents unwanted movement, minimizing wear on the shaft and adjacent components.
