4.2 Advice regarding finish bore
STOP
D A N G E R !
The maximum permissible bore diameters d
1max
and
d
2max
(see RADEX
®
-N catalogue) must not be
exceeded. If these figures are disregarded, the
coupling may tear. Rotating particles may cause
danger to life.
Hub bores machined by the customer have to observe
concentricity or axial runout, respectively (see
illustration 4).
Please make absolutely sure to observe the figures
for Ø d
1max
and Ø d
2max
.
Carefully align the hubs when the finish bores are
drilled.
Please provide for a setscrew according to
DIN EN ISO 4029 with cup point or an end plate for
the axial fastening of the hubs.

4.3 Displacements - alignment of the torque measuring shaft
The displacement figures shown in table 4 provide for sufficient safety to compensate for external influences like,
for example, heat expansion or foundation settling.
!
C A U T I O N !
In order to ensure a long service life of the measuring shaft the shaft ends must be
accurately aligned. Please absolutely observe the displacement figures indicated (see
table 4). If the figures are exceeded, the measuring shaft with coupling will be damaged.
Please note:
The displacement figures given in table 4 are maximum values. They cannot occur at the same time.
When radial, axial and angular displacement occurs simultaneously, these values must be reduced (see
illustration 6).
Please inspect with a dial gauge, ruler or feeler whether the permissible displacement figures of table 4 can be
observed.
