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.

这可以提高轴承的刚度，和主轴精密的径向引导，对于特别的运用，密排的圆柱滚子轴承被运用，圆柱轴承的图样在图。20和1.21展示圆柱滚子轴承图样由挡边的不知来区分，图样NU(图1.21b)在外圈有两个挡边，内圈无挡边，在图样N中内圈有两个挡边，外圈无挡边，图样NU和U所示的圆柱滚子轴承可制作浮动轴承因为滚子能够在轴向无挡边环上自由的移动，圆柱滚子轴承NG在外圈上有两个挡边，内圈上有一个，它们能够在某个方向上承受轴向力，图样NUP（图1.21d）被用来安装在一个保持经常扭转轴向力的固定轴承上。

In this time, we can recognize the number image depending on the location of the end-point. If the y-coordinate of the end-point is bigger than half of the height of the number image, the recognized result is 6. Else the result of recognition is 9. Then if there are two end-points and there is no trifurcate point, the possible recognition result of the number image is 2, 3, 5 or 7. Here, we need to recognize the number image by dint of the end-point directions and locations.

最后，我们根据特征提取的结果进行分类识别，如果没有端点、没有三叉点，则识别结果为0；如果无端点，两个三叉点，则识别结果为8；如果只有一个端点、一个三叉点，则识别结果可能为6或9，这时只需考虑端点的位置，即可将6和9区分开来；如果有两个端点、无三叉点，则识别结果可能为2、3、5、7，这时需要加入端点的位置和方向辅助判断。
