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, flange hub or 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 hubs 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 or L
Z
(see table 1 and 3) is
kept to ensure that the elastomer part can be moved axially.
Disregarding this hint may cause damage on the coupling.
Applying for type HEW-ZS only (size 100 to G 125)!
Screw the flange hub (component 4.2) to the additional flange (component 4.1) at the tightening torques T
A
mentioned in table 7.

Assemble the hub, flange hub or adaptor flange onto the shaft of driving and driven side.
Shift the power packs in axial direction until the installation dimension L
HEW1
, L
HEW2
or L
HEW-ZS
has been
achieved.
If the power packs have already been firmly mounted, the mounting dimension has to be adjusted by shifting
the hub, flange hub or coupling flange axially on the shafts.
Fasten the hub, flange hub or coupling flange by tightening the setscrews DIN EN ISO 4029 with cup point
(tightening torque see table 5).
Applying for type HEW-ZS only!
Put the hub spec. (component 2) in front of the hub ZW (component 3) and screw the components at the
tightening torques T
