Product Overview: The NJ 210 Cylindrical Roller Bearing
The NJ 210 is a high-performance single-row cylindrical roller bearing, engineered with principal dimensions of 50x90x20mm. As a key component in our Cylindrical Roller Bearings range, this model is part of the versatile NJ 200 Series. Its specific design features two integral flanges on the outer ring and a single flange on the inner ring. This configuration allows the bearing to accommodate heavy radial loads while also locating the shaft axially in one direction, making it ideal for applications requiring both robust support and controlled shaft movement.
The separable nature of the NJ 210, where the inner ring can be mounted independently from the outer ring and roller assembly, significantly simplifies the installation and maintenance process. Manufactured to precise industry standards, this bearing ensures high stiffness, low friction, and a long operational lifespan, even in the most demanding industrial environments. For applications requiring axial location in both directions, it can be used in conjunction with an angle ring (HJ type).
Key Features of the NJ 210 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways allows it to support heavy radial loads.
- Axial Location: Provides axial shaft location in a single direction, preventing unwanted movement.
- Separable Design: The inner ring can be removed, facilitating easier mounting, dismounting, and inspection.
- High Stiffness: Its robust construction offers excellent rigidity, essential for precision machinery.
- Low Friction Operation: Engineered for minimal friction, which reduces heat generation and improves efficiency.
- Durable Construction: Made from high-quality bearing steel for superior wear resistance and long-term reliability.
