In the dimensional plans, several outside diameters and width dimensions are assigned to each bearing bore diameter (Figures 1.761.78 and Table 1.9).

在尺寸方案，几个外径和宽度尺寸被标示为每个轴承孔直径(数字1.761.78和表1.9)。

In this way, code NU2308 is obtained for a cylindrical roller bearing with a 40 mm bore diameter (Section 1.6).

用这种方法，获得了NU2308为代码的孔直径40毫米的圆柱滚子轴承(16节)。
