6.10 Fitting of assemblybalanced couplings
On couplings which have been assemblybalanced each individual coupling component must be marked
on the outside diameter of the flange with a fourdigit number (Figure 20, "AAAA"). When assembling, care
must be taken that only coupling parts having the same numbers on the outside circumference of the flange
are bolted together. The coupling parts must be arranged so that the numbers are in line and can be read
from one direction (see figure 20). Only in this way will the balancing condition meet the requirements!
