Single row cylindrical roller bearings 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. Cylindrical roller bearings are commonly separable and easy to mount and dismount. They can accommodate heavy radial loads and high speeds. The widely used bearings are cylindrical roller bearings with cage. The 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 treated roller ends, provide improved lubrication, reduced friction and consequently lower operating temperature.

Applications of BEART high precision single row cylindrical roller bearing: machine tool, spindle, measuring equipment.
