The displacement figures specified in tables 6 and 7 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 and avoid dangers with the use in
potentially explosive atmospheres, the shaft ends must be accurately aligned.
Please absolutely observe the displacement figures specified (see tables 6 and 7). If the
figures are exceeded, the coupling will be damaged.
The more accurate the alignment of the coupling, the longer is its service life.
If used in potentially explosive atmospheres for explosion group IIC, only half of the
displacement figures (see tables 6 and 7) is permissible.
Please note:
•
The displacement figures specified in tables 6 and 7 are maximum figures which must not arise in parallel. If
radial and angular displacement arise at the same time, the permissible radial displacements of the coupling
halves have to be reduced as follows:
Ww
Kw

The displacement figures specified are general standard figures that apply up to an ambient temperature of
80 °C, ensuring a sufficient service life of the

coupling.
Displacement figures between the speeds specified have to be interpolated accordingly. If necessary, ask
about the displacement for the corresponding coupling type.
•
Please inspect with a dial gauge, ruler or feeler whether the permissible displacement figures of tables 6 and 7
can be observed.
