Cylindrical Roller Bearings are manufactured in a number of designs; the predominant type being the single row roller. The roller and cage assembly are guided axially by the integral flanges (ribs) on one of the bearing rings. This design facilitates ease of mounting and dismounting, particularly where both races are an interference fit on their seating. Roller bearings with flanges (ribs) on one race only do not provide any end location.
Various Roller Bearings with ribs on both races provide axial location. They are also capable of carrying light or intermittent axial loading. These patterns are of the NJ, NUP, NJ and HJ types. The contact between the flanges (ribs) and the roller ends is that of a sliding bearing if used for axial location and light axial loads. Since it is not that of a rolling bearing, lubrication is of paramount importance. Double row and full complement Cylindrical Roller Bearings are also manufactured .
