4.2 Hint regarding the finish bore
STOP
D A N G E R !
The maximum permissible bore diameters d (see table 1 in
chapter 1 - Technical Data) must not be exceeded. If these
figures are disregarded, the coupling may tear. Rotating
particles may cause serious danger.
•
Hub-/coupling flange bores machined by the customer have to
observe concentric running or axial running, respectively (see
picture 5).
•
Please make absolutely sure to observe the figures for d
max
.
•
Carefully align the hub and the coupling flange when the finish
bores are brought in.
•
Please provide for a setscrew or an end plate for the axial
fastening of the hub and the coupling flange.

4.3 Assembly of the Coupling
A T T E N T I O N !
We recommend to check bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hub and coupling flange slightly (approx. 80 °C) allows for an easier installation onto the shaft.
P R E C A U T I O N !
Please pay attention to the danger of ignition in hazardous areas.
STOP
D A N G E R !
Touching the heated parts causes burns.
We would recommend to wear safety gloves.
!
C A U T I O N !
For the assembly please make sure that the distance dimension E (see table 1) is kept to
ensure that the elastomer part can be moved axially.
Disregarding this hint may cause damage on the coupling.
•
Assemble the hub and the coupling flange onto the shafts.
•
Safe the coupling hub and the coupling flange by tightening the setscrews DIN 916 with cup point or by an end
disk.
•
Put the elastomer part in front of the flange hub.
•
First hand-screw the parts.
•
Use screws of the property class 8.8 or higher.
•
Tighten the screws with a suitable dynamometric key up to the tightening torques T
A
indicated in table 4.
