4.4 Displacements - alignment of the couplings
Please note:
 The displacement figures specified in tables 13 and 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 14).
 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 BoWex-ELASTIC
Displacement figures between the speeds specified have to be interpolated accordingly. If necessary, please
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 13 and
14 can be observed.
