The displacement figures specified in table 5 provide for sufficient safety to compensate for external influences
like, for example, thermal expansion or foundation settling.
!
In order to ensure a long service life of the coupling, the shaft ends have to be accurately
aligned. Please absolutely observe the displacement figures specified (see table 5). If the
figures are exceeded, the coupling will be damaged.
The more accurate the alignment of the coupling, the longer is its service life.
Please note:
The displacement figures specified in table 5 are maximum figures which must not arise in parallel. If radial
and angular displacements arise at the same time, the permissible displacement values may only be used
proportionally (see illustration 12).
Please inspect with a dial gauge, ruler or feeler gauge whether the permissible displacement figures specified
in table 5 can be observed.
