Procedure
The machine axis must be vertical when it is lifted and the ange must be parallel to the mating
ange, so as to avoid seizing and stressing. Otherwise damage to the centering will result.
1. Grease the centering ange with assembly paste to make the process easier.
2. Screw in two studs into tapped holes on opposite sides of the driven machine ange. The
studs act as positioning aids.
3. Lower the machine slowly toward the driven machine and into the centering, so that the
anges do not quite touch. Lowering too quickly risks damaging the centering.
4. If necessary, rotate the machine into the right position so that the clearance holes in the
ange are central to the tapped holes.
5. Lower the machine completely onto the mating ange so that it is fully in contact; then
remove the studs.
6. Fix the machine using the ange xing bolts.

5.5.3 Removing the rotor shipping brace
If a rotor shipping brace is attached to the machine, remove it at the last possible moment,
forexample, when you are ready to push on the output or drive element.
Storing the rotor locking device
Store the rotor locking device in a safe place. It must be remounted if the machine is removed
and shipped on further.
5.5.4 Recommended alignment accuracy
The alignment accuracy required depends essentially on the conguration of the overall
machine train. Observe the required alignment accuracy of the coupling manufacturer in all
cases when aligning the machine.
