FLENDER N-EUPEX - Figure 5-3 Position of the Balancing Bore for Single-Plane Balancing; Figure 5-4 Position of the Balancing Bore for Two-Plane Balancing

Please note the following when balancing the coupling:
● Select the balancing quality according to the application (but at least G16 in accordance
with DIN ISO 21940).
● Observe the balancing specification according to DIN ISO 21940-32.
● Machine the balancing bore on a large radius with adequate clearance to the flexible
element webs / pockets and to the cams and the outer circumference.

Note
A better balancing result can be achieved by balancing the coupling parts (2 and 3) when they
are bolted together as an assembly. When balancing all parts together, mark the position of
the components relative to one another.
