The drive shaft end must be free
from dirt, oil and grease
Fit the coupling and prepare as
described above. If specified, set the
mounting dimension of the coupling
in accordance with the dimension
sheet. Tighten clamp screw.
Install lantern and tighten
screw(s).
The coupling can be tightened on
the motor side through the bore at
the top. It is recommended to turn
the lantern such that this bore is
located on the side of the terminal
box of the motor.
The mounting dimension of the coupling to the gearbox is stated in the corresponding dimension sheet. If
nothing to the contrary has been stated there, push the coupling onto the shaft until it rests against the shaft
shoulder.
After tightening the coupling, place the motor lantern in position and screw it tight, ensuring that the bores
provided for tightening the clamp screws on the coupling are located on the same side as those on the motor.

b. Mounting the Motor
Preferred installation in the vertical position. Always position the motor shaft with the gear shaft such that it is in
alignment with the coupling. The metal bellows of the coupling must be neither bent nor axially compressed
during assembly. Do
not
drive in the motor with a hammer, but use suitable bores and threads on the gearbox
and motor to allow it to slide into position with assembly screws into the centring seat until the motor is in close
contact; then tighten the coupling on the motor side.
There must be no distortion of the bearings or coupling.
After tightening the clamp screws, insert plug into the bore.
Attention
gearbox damage:
Due to incorrect assembly the coupling can become compressed or bent!
Due to the bearings becoming distorted, overheating of the same may occur
which then causes damage to the bearings ending in blockage.
The shaft seal rings and the running surfaces of the shafts must not be damaged
when fitting the coupling parts. Otherwise leakages may occur!
Other coupling types and versions can also be installed on request!
As a matter of principle, we refer to the assembly and operating instructions of the respective coupling
manufacturer!
