3 type and size
3.1 conical shaft extension divided into A and B type two. As shown in Figure 1. According to the length of the shaft extension, and it is divided into a long series of short series two kinds.
Which are parallel to the axis of the bottom surface of the keyway.
3.2 long series of conical shaft extension should be sized in accordance with Table 1.
3.3 short series conical shaft extension should be sized in accordance with Table 2.
