Product Overview: The NJ 2212 Cylindrical Roller Bearing
The NJ 2212 is a high-capacity, single-row cylindrical roller bearing designed for demanding industrial applications. As a key component in our Cylindrical Roller Bearings range, this bearing features dimensions of 60x110x28mm and is part of the versatile NJ 2200 Series. Its specific design, part of the broader NJ Series, includes two integral flanges on the inner ring and one on the outer ring. This configuration allows the bearing to accommodate heavy radial loads while also locating the shaft axially in a single direction, making it an excellent choice for non-locating bearing positions that require some axial guidance.
Manufactured to precise industry standards, the NJ 2212 bearing ensures reliable performance and a long service life. Its separable design, where the outer ring can be mounted independently of the inner ring and roller assembly, significantly simplifies the installation and maintenance processes. This bearing is engineered to operate efficiently at high speeds, making it suitable for a wide variety of machinery.
Features of the NJ 2212 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 the bearing to guide the shaft and handle incidental thrust loads in one direction.
- Separable Design: The inner and outer rings can be mounted separately, facilitating easier installation, inspection, and maintenance.
- High-Speed Performance: Engineered for low friction and optimal roller geometry, enabling operation at high rotational speeds.
- Robust Construction: Made from high-purity, hardened bearing steel for exceptional durability and resistance to wear.
- Interchangeability: Produced to standard dimensions, allowing for easy replacement and interchangeability with other manufacturers' bearings.
Applications of NJ 2212 Bearings
- Industrial Gearboxes: Provides rigid support for gears and shafts, ensuring proper mesh and power transmission.
- Electric Motors: Used in large motors to support the rotor shaft under heavy radial forces.
- Pumps and Compressors: Ensures the stability and smooth rotation of shafts in industrial fluid machinery.
- Construction and Mining Equipment: Ideal for heavy-duty machinery like excavators, loaders, and crushers that experience significant loads.
- Vibrating Screens and Shakers: Withstands the high radial forces and vibrations common in material processing applications.
- Rolling Mills: Supports the rollers in steel and metal processing plants where loads are extreme.
- Automotive Transmissions: Used in gear systems to handle the demanding torque and speed requirements.
Benefits of Using the NJ 2212 Bearing
- Enhanced Operational Reliability: Its robust design significantly reduces the risk of premature failure in high-load conditions.
- Improved Shaft Guidance: Provides effective axial location in one direction, simplifying the overall bearing arrangement.
- Reduced Maintenance Downtime: The ease of mounting and dismounting due to its separable nature speeds up maintenance tasks.
- Increased Machine Uptime: The long service life and durability contribute to fewer breakdowns and more productive hours.
- Versatile Application Range: Combines radial and single-direction axial support, making it adaptable to various industrial needs.
- Efficient Operation: Low-friction characteristics help to minimize energy loss and heat generation during operation.
