120 FLUDEX 90° to the threaded hole
Table5-3: Position of the parallel keyway
Applicable standards
• Machine the parallel keyway according to DIN6885/1ISOJS9 .
• If you want to mill a parallel keyway that does not correspond to DIN6885/1, please con-
sult Flender.
5.1.3 Machining an axial locking mechanism5.1 Preparatory work
The coupling part is secured by a set screw or an end plate to prevent axial movements.
