Product Overview: The NJ 2216 Cylindrical Roller Bearing
The NJ 2216 is a high-capacity single-row cylindrical roller bearing, engineered to accommodate heavy radial loads and high speeds. With principal dimensions of 80mm Bore Diameter, 140mm Outer Diameter, and 33mm Thickness, this bearing is a vital component in a wide array of industrial machinery. As part of our NJ 2200 Series, the NJ 2216 features two integral flanges on the outer ring and a single flange on the inner ring, allowing it to locate the shaft axially in one direction. Its separable design, where the inner ring can be mounted independently of the outer ring and roller assembly, simplifies installation, inspection, and maintenance procedures. This makes it an excellent choice for applications requiring robust performance and reliability. Explore our full range of Cylindrical Roller Bearings to find the perfect solution for your needs.
Key Features of the NJ 2216 Bearing
- High Radial Load Capacity: The line contact between rollers and raceways provides excellent capacity for heavy radial loads.
