Mounting Instructions:
The split-hub design allows for easy assembly. Further simplification during installation is provided because one half of the split hub can be put onto the shaft. 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 a “one man assembly” possible.

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

order example:
KPH 80 – D1 = 24 G7 D2 = 30 G7
KMH 400 – D1 = 38 F6 D2 = 48 F6
