|In a single row cylindrical roller bearing ,the rollers are always guided between the integral "open flanges" on one of the rings. These "open flanges" combined with the specially designed and surface treated 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. They are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs.
