Machining the finished bore

Remove the flexible elements (12).
Depreserve and clean coupling parts (2; 2/3; 4; 9).
Clamp on surfaces marked with
In case of coupling part 2/3, coupling part 4 and coupling part 9 great caution is
necessary owing to the rotating cams.
Machine the finished bore, observe maximum bore described in section 1.
Check finished bore as described in section 4.

Bore tolerance
The fit assignment m6 / H7 is particularly suitable for many applications.
Failure to observe these instructions may result in breakage of the coupling.
Danger from flying fragments!
The coupling may then become an explosion hazard.

Machining the parallel keyway

• Parallel keyway to DIN 6885/1 ISO JS9 with usual operating conditions.
• Width of parallel keyway ISO P9 with reversing operation.
Arrangement of parallel keyway:
─ with coupling part 2:
─ with coupling part 4:
─ with coupling part 9:
