We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft.
Please pay attention to the ignition risk in potentially explosive atmospheres!
STOP
Touching the heated hubs causes burns.
Please wear safety gloves.
!
With the assembly make sure that the distance dimension E (see table 1 and 3) is observed
to allow for axial clearance of the sleeve while being in operation.
Disregarding this advice may cause damage to the coupling.
!
With the assembly please make sure that the spline of the hub is fully covered by the
internal spline of the elastomer. (Please observe mounting dimensions L, L
HEW1
, L
HEW2
or
L
HEW - ZS
.)
Disregarding this advice may cause damage to the coupling.
If used in potentially explosive atmospheres the setscrews to fasten the hubs as well as all
screw connections must be secured against working loose additionally, e. g. conglutinating
with Loctite (average strength).
•
Valid for type HEW-ZS only (size 100 to G 125):
Screw the flange hub (component 4.2) with the additional flange (component 4.1) at the tightening torques T
A
specified in table 9.

•
Mount the hub, the flange hub with additional flange or the coupling flange onto the shaft of the driving and
driven side.
•
Shift the power packs in axial direction until the mounting dimension L, L
HEW1
, L
HEW2
or. L
HEW-ZS
has been
achieved.
•
If the power packs have already been firmly assembled, shifting the hub, the flange hub or the coupling flange
or coupling flange axially on the shafts allows for adjusting the mounting dimension.
•
Fasten the hub, the flange hub or the coupling flange by tightening the setscrews DIN EN ISO 4029 with a cup
point (tightening torques see table 7).
•
Valid for type HEW-ZS only:
Mount the hub spec. (component 2) in front of the intermediate shaft hub (component 3) and screw the
components at the tightening torques T
A
specified in table 10.
