Only transfer radial or axial forces specified in the catalog to the machine bearings via the
shaft extension.
You can obtain the permissible values for axial and radial forces by contacting the Service
Center (Page 117) or by referring to the machine catalog.
Shaft extensions with feather key
The feather key data for the shaft and drive output element must match and indicate the
correct type of balancing. The drive output element must be correctly mounted.
The balance quality corresponds to vibration severity grade "A" for the complete machine;
vibration severity grade "B" is possible as an option. To ensure the required balance quality, it
must be ensured that the feather key data on the hub and machine shaft match in the case
of a shorter or longer drive output element.
• If the drive output element is shorter than the feather key with balancing type "H", then you
must machine off the section of feather key protruding from the shaft contour and drive
output element in order to maintain the balance quality.
• If the drive output element is longer than the feather key, when balancing the coupling, take
into account that the feather key does not take up all of the coupling slot.
