restoring forces.
 Silent operation and noise damping.
 Backlash free, torsionally rigid and radially rigid.
 Low-maintenance, free of wear.
 Easy visual inspection.
 Fast exchange of components.
 No special tools required.
 The design is protected by international patents.
 Type approval from leading classification agencies.

016L-00050...00090-SS/FS/FF20

5 Alignment of the units being connected

IMPORTANT
 Align the units during the assembly.
 Align the units that are to be connected as accurately as possible. In this way, a
long service life for the coupling and maximum operating misalignment values can
be achieved.
The overall misalignment is composed of the misalignment and the operating
misalignment. The permissible overall misalignment values can be found in the
corresponding catalogue and must not be exceeded.
 All permissible alignment tolerances apply to arrangements at operating
temperatures.
If the arrangement would be aligned at a different temperature, there would be
additional deviations in the arrangement, which were produced by the difference
between the aligning and operating temperature.
For alignment, this has to be taken into account.
 After completion of assembly, check the alignment of the coupling again and if
necessary correct.
