This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.
