Product Overview: The NJ 214 Cylindrical Roller Bearing
The NJ 214 bearing is a high-performance, single-row cylindrical roller bearing with dimensions of 70x125x24mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to handle heavy radial loads at high speeds. Its specific NJ design features two integral flanges on the inner ring and a single integral flange on the outer ring. This configuration allows the bearing to locate the shaft axially in one direction, making it suitable for applications requiring precise shaft guidance. Part of the versatile NJ 200 Series, the NJ 214 is manufactured to exacting standards for reliability and durability in demanding industrial environments.
Key Features of the NJ 214 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 for the axial location of the shaft in one direction, providing stability and positional control.
- Separable Design: The inner ring can be mounted independently of the outer ring and roller assembly, which simplifies the installation, inspection, and maintenance processes.
- High Stiffness: Offers a high degree of rigidity, making it ideal for applications where shaft deflection must be minimized.
- Low Friction Operation: An optimized internal design minimizes friction and heat generation, enhancing operational efficiency and extending service life.
- Robust Construction: Manufactured from high-purity, hardened bearing steel for superior wear resistance and long-term performance.
