Balance quality
The rotor is dynamically balanced. For shaft extensions with featherkeys, the balancing type
is specified using the following coding on the face of the drive end of the shaft:
● "H" means balancing with a half feather key
● "F" means balancing with a whole feather key.

Applies to electrical connections in which the permissible torque is normally limited by the
bolt materials and/or the current carrying capacity of the insulators, with the exception of
the busbar connections in case B.
Applies to bolts screwed into components made from lower-strength materials (e. g.
aluminum) and to bolts of strength class 8.8 to ISO 898-1.
Applies to bolts of strength class 8.8 or A4-70 to ISO 898-1, but only to bolts screwed into
components made from higher-strength materials (e. g. gray cast iron, steel or cast steel).
Note
Non-standard tightening torques
Different tightening torques for electrical connections and bolted connections for parts with
flat seals or insulating parts are specified in the relevant sections and drawings.
