    Fixing to the machine:
    Fixed to the machine with n°3 M5 cheese head Allen screws (position 9 in the drawing), DIN 912.

    Graduated flange:
    The standard numbering on the scale ring goes from 0 to ) with 10 graduations for each unit, (total of 100 graduations). For a minimum quantity of 30 pieces numbering can be executed to customer's specifications.

    Locking shaft to control knob:
    The shaft is coupled to the knob by means of the shaft with keyway. Caution! For technical reason the keyway is very small. See attached diagram for bore/shaft dimensions. (DIN 6885-2).

    The bore of the insert is executed with H7 tolerance. It does not require a side bore for fixing. The diameter of the bore is fixwd and cannot be varied or enlarged.

    On request the cover cap ca be provide in the colours specified in the colour table page [pageTitoloTabellaColori.
    Upon requestand for sufficient quantities (30 pieces) the numbering on the scale ring can be customized.

    The main feature of this product is the possibility of making a continuous adjustment of the machine shaft to which it is attached and of maintaining the selected position. The special clutch, the heart of the mechanism, permits very small continuous movements and therefore the possibility of making precision adjustments in both directions. Once the desired position is reached, the clutch prevents any rotation caused by small vibrations or movements arriving from the shaft. The use of this system prevents accidental or involuntary rotation of the shaft.

    The clutch is not sufficient to block any movements caused by strong vibrations. Moreover the control knob is not capable of withstanding the weight of the shaft, therefore it does not replace the normal support systems ( bearings, flanges, etc...). The control knob cannot be used with motor drive systems.
