Product Overview: The NJ 224 Cylindrical Roller Bearing
The NJ 224 is a high-capacity single-row cylindrical roller bearing with principal dimensions of 120x215x40mm. As a key component in our Cylindrical Roller Bearings range, it belongs to the versatile NJ 2200 Series. The NJ design features two integral flanges on the outer ring and one integral flange on the inner ring, enabling it to accommodate axial displacement of the shaft in one direction while providing axial location. This makes it ideal for applications requiring heavy radial load support and precise, single-direction shaft positioning.
Engineered for reliability in demanding industrial environments, the NJ 224 bearing's line contact between the rollers and raceways provides a high degree of stiffness and superior radial load-carrying capacity. Its separable design, where the inner ring can be mounted separately from the outer ring and roller assembly, simplifies installation and maintenance procedures. Trust our expertise as a leading supplier to provide high-quality mechanical components for your most critical machinery.
Features of the NJ 224 Bearing
- High Radial Load Capacity: The cylindrical rollers and raceways provide line contact, allowing for the support of heavy radial loads.
