Procedure
The machine axis must be vertical when it is lifted and the flange must be parallel to the mating
flange, so as to avoid seizing and stressing. Otherwise damage to the centering will result.
1. Grease the centering flange with assembly paste to make the process easier.
2. Screw in two studs into tapped holes on opposite sides of the driven machine flange. The
studs act as positioning aids.
3. Lower the machine slowly toward the driven machine and into the centering, so that the
flanges 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
flange are central to the tapped holes.
5. Lower the machine completely onto the mating flange so that it is fully in contact; then
remove the studs.
6. Fix the machine using the flange fixing bolts.
