The NJ Series NJ344 rollers in a single row cylindrical roller bearing are always guided between the integral 'open' flanges on one of the rings. These 'open' flanges combined with the specially designed and surface finished roller ends, provide improved lubrication, reduced friction, and consequently lower operating temperature. The ring with the integral flanges together with the cylindrical roller and cage assembly can be separated from the other ring. This results in easy mounting and dismounting, particularly where the load conditions are such that interference fits are required for both rings. Single row cylindrical roller bearings can accommodate heavy radial loads and high speeds.
