Types of misalignment
~~
There are two basic types of misalignment, angular and parallel. Within
each of these basic types of misalignment there are combinations of
both. These are the most common combinations:
w Vertical/angular misalignment (Figure 10-2
w Vertical/parallel misalignment (Figure 10-3)

w Horizontal/angular misalignment (Figure 104)
w Horizontal /parallel misalignment (Figure 10-5)
w Combined angular and parallel misalignment

Coupling with Bore Not Perpendicular
Excentric Bore to Face

Figure 10-6 and Figure 10-7 Misalignment can be transmitted through the couplings and
couDlina faces.
