The displacement figures specified in table 12 to 14 provide for sufficient safety to compensate for external
influences like, for example, heat 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 indicated (see table 12 to 14). 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 table 12 to 14) are permissible.
Please note:
•
The displacement figures specified in table 12 to 14 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 25).
•
Please inspect with a dial gauge, ruler or feeler whether the permissible displacement figures of tables 12 to
14 can be observed.
