Product Overview: The NJ 211 Cylindrical Roller Bearing
The NJ 211 is a high-capacity single-row cylindrical roller bearing designed to handle demanding industrial applications. With principal dimensions of 55mm bore diameter, 100mm outer diameter, and 21mm thickness, this bearing is part of our robust NJ 200 Series within the broader Cylindrical Roller Bearings category. The NJ design features two integral flanges on the outer ring and a single integral 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 an excellent choice for applications requiring precise shaft guidance.
As a leading supplier, we ensure our NJ 211 bearings are manufactured to the highest industry standards, offering superior performance and reliability. The separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, greatly simplifies installation, inspection, and maintenance procedures. This versatility makes it a cornerstone component in a wide array of industrial machinery.
Key Features of the NJ 211 Bearing
- High Radial Load Capacity: Engineered with line contact between the rollers and raceways to support substantial radial forces.
- Single-Direction Axial Location: The single flange on the inner ring provides positive axial location for the shaft in one direction.
- Separable Design: The inner ring is separable from the outer ring and roller cage assembly, allowing for easier mounting and dismounting.
- Low Friction Operation: Precision engineering of the internal geometry minimizes friction, reducing heat generation and energy consumption.
- High-Speed Performance: Suitable for applications that operate at high rotational speeds without compromising stability.
- Durable Construction: Manufactured from high-quality, clean bearing steel for extended service life and excellent wear resistance.
