Key for standard hub and clamping hub
4.4.3 Coupling hubs
General
 Note!
Standard hubs, clamping hubs and clamping ring hubs are
maintenance−free.We recommend checking the star−shaped spider and
system components when inspecting the drive.
Mounting the standard hub / clamping hub
1. Fit motor key (2).
– Fit enclosed key for drive sizes C, E, F.
2. Push the coupling hub over the motor shaft, mounting dimension m (see Fig. 2
and Tab. 2) must be observed.
3. Secure coupling hub against axial movement using the fixing screw or clamping
screw (1).
4. Lay spider in the coupling claw on the gearbox side.
5. Align claws of the motor−side coupling hub with its counterpart.
6. Slowly push on motor, and bolt on to the gearbox flange.
