Product Overview: The NJ 212 Cylindrical Roller Bearing
The NJ 212 is a high-performance, single-row cylindrical roller bearing with principal dimensions of 60x110x22mm. As a key component in our NJ 200 Series, this bearing is engineered to accommodate heavy radial loads and high-speed operation. Its distinctive design features two integral flanges on the outer ring and a single integral flange on the inner ring. This configuration allows the bearing to provide axial location for a shaft in one direction, making it an excellent choice for applications requiring both radial support and unidirectional axial guidance. Part of our comprehensive Cylindrical Roller Bearings range, the NJ 212 is manufactured to precise standards, ensuring reliability and longevity in demanding industrial environments.
Key Features of the NJ 212 Bearing
- High Radial Load Capacity: The line contact between the cylindrical rollers and raceways provides a large contact area, enabling the bearing to support heavy radial forces.
- Single-Direction Axial Location: The flange arrangement allows the bearing to accommodate axial loads in one direction, effectively locating the shaft.
- Separable Design: The inner ring can be separated from the outer ring and roller assembly, which simplifies the mounting and dismounting process, especially in tight-fit applications.
- High-Speed Performance: Engineered with low-friction geometry, the NJ 212 is suitable for applications involving high rotational speeds.
- Enhanced Rigidity: Provides a high degree of stiffness to the bearing arrangement, which is critical for applications requiring precise shaft guidance and minimal deflection.
- Durable Construction: Manufactured from high-purity, through-hardened bearing steel for superior wear resistance and a long service life under tough conditions.
Common Applications for NJ 212 Bearings
