1) Please make absolutely sure to adhere to the distance dimension E specified for the various types, specifically with radial and angular
displacement (see tables 1, 3, 5 and 7).
!
In order to ensure a long service life of the coupling the coupling must be aligned to at least
20 % of the displacement combinations that may arise during operation (see illustration 27
and 28). Please absolutely observe the displacement figures specified (see table 11). If the
figures are exceeded, the coupling will be damaged.
In order to improve the lubrication effect of the coupling, a minimum angular displacement
of 0.1° per displacement level must be observed.
Misalignment of the coupling components versus one another may have been generated by incorrect alignment
with assembly or operation of the machine (thermal expansion, shafts bending, elastic machine mounts, etc.).
The displacement figures specified in table 11 are maximum figures which must not arise in parallel.
If radial and angular displacement arises at the same time, these values must be reduced (see illustration 28).
