Mounting Instructions:
The split-hub design allows for a easy assembly. Further simplification during installation
is provided because one half of the split hub is put onto the shaft. This allows that the
coupling can rest on the two shaft ends. The second half of the split hub can then be
mounted to the coupling by screwing it on from below with the specified tightening
torque. This feature makes “one man assembly” possible.

Important: the distance between the shafts must be bigger than ‘g’!

order example:
KGH – VA 200 / 4W – D1 = 32 G7 D2 = 35 G7 – stainless steel screws
KGH – VA 50 / 2W – D1 = 16 G7 D2 = 19 G7 – coated screws
