Standard fitting procedure for 2-part shrink discs:
1. Remove the cover if present
2. Loosen the tensioning bolts of the shrink disc but do not remove them. Tighten them gently by
hand until there is no play between the flanges and the inner ring.
3. Push on the shrink disc up to the specified position (refer to the specific dimension sheet for the
order).
4. The solid shaft of the machine must be completely de-greased prior to assembly.
a. Do not apply grease to standard hollow machine shafts.
b. In the case of special hollow shafts with a bronze bushing, the solid shaft of the machine must
be greased in the area which will later come into contact with the bushing in the hollow shaft of
the gear unit (Figure 12). It is essential that the tensioning seat of the hollow shaft is free of
grease.

5. The hollow shaft of the gear unit and its bushing must be completely de-greased in order to avoid
accidental greasing in the area of the shrink connection.
6. Insert the solid shaft of the machine into the hollow shaft so that the area around the shrink
connection is completely filled.
7. Evenly tighten the tensioning bolts of the shrink disc in sequence in the clockwise direction in
several stages.
