Product Overview: The NJ 228 Cylindrical Roller Bearing
The NJ 228 bearing is a high-performance cylindrical roller bearing with dimensions of 140x250x42mm. As a key component in our Cylindrical Roller Bearings category, it belongs to the versatile NJ 2200 Series. This bearing is engineered with two integral flanges on the outer ring and one on the inner ring, allowing it to locate a shaft axially in a single direction. Its design is ideal for applications requiring high radial load capacity and moderate axial guidance. The separable nature of the bearing, where the inner ring can be mounted independently of the outer ring and roller assembly, significantly simplifies installation and maintenance procedures.
Key Features of the NJ 228 Bearing
- Single-Direction Axial Location: The flange arrangement provides reliable axial positioning of the shaft in one direction.
- High Radial Load Capacity: Designed with line contact between rollers and raceways, it can support heavy radial loads.
- Separable Design: The inner and outer rings can be mounted separately, which simplifies installation, inspection, and maintenance routines.
- High-Speed Capability: The low-friction design and precision manufacturing make it suitable for high-speed rotational applications.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life.
- Reduced Edge Stresses: The logarithmic profile of the rollers minimizes stress concentrations at the roller ends, enhancing reliability under load.
Common Applications
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Pumps and Compressors: Used to support rotating shafts, ensuring efficient and reliable operation under demanding conditions.
- Electric Motors and Generators: Ideal for supporting motor shafts, accommodating high speeds and significant radial loads.
