Shaft extensions with feather key
To maintain the balancing quality, you have the following options:
● If the transmission 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
transmission element in order to maintain the balance quality.
● If the output element is mounted up to the shaft shoulder for motors with full-key balancing
"F", or if the output element is longer than the motor shaft extension, then when balancing
the coupling or belt pulley, take into account that the feather key does not completely fill
the slot in the hub.
WARNING
The feather key can fall out
The feather keys are only locked against falling out during shipping. If a machine with two
shaft extensions does not have an output element on one shaft extension, the feather key
can fall out during operation.
Death or serious injury can result.
● Do not operate the machine unless the transmission elements have been pulled on.
● On shaft extensions without output element, make sure that the feather key cannot fall
out and shorten it by approximately half for balance type "H".
Note
Type of balancing
In the case of shaft extensions with feather keys, the type of balancing is also included on the
rating plate next to the CE mark.
5.2.5 Lifting and transporting the machine

transport frames using a fork-lift truck or a crane with slings. Use a crane or fork-lift truck
suitable for the load.
● When lifting the machine, use only approved and undamaged sling guides and spreaders
of sufficient rated capacity. Check the lifting equipment prior to its use. The weight of the
machine is shown on the rating plate.
