The untensioned clutch hub has a fitting clearance to the motor shaft of 0.01 to 0.05 mm.
As a consequence of the frictional hub-clamp connection and the axial pre-tensioning of
the conical plug-in segments, the plug-in connector works with absolute zero-backlash.
Assembly:
1. Degrease the motor shaft and the clutch hub on the motor side.
2. Put the slotted clutch hub on the motor shaft and slide it against the shaft shoulder;
check the axial position of the hub.
3. Tighten the locking screw as shown in Table 3.
Table 3: Tightening torque
4. Screw the motor to the adapter casing, tighten the fixing screws as shown in Table 3.

CAUTION
When setting the motor on the adapter casing, the plastic cams of the motor-side
hub must be carefully inserted into the corresponding recesses in the gear side
clutch bush so that the metal bellows are not compressed or bent.
