
If the clamping bolt [H
1
] is loosened too far or removed, the clamping ring [I] can rotate on the
clamping hub. Align it so that the clamping bolt [H
1
] is in the keyway of the clamping hub (see
table "Tbl-10").

For certain motor shaft diameters and applications, a slotted bushing needs to be installed in
addition.

For the version with clamping bolt, eccentrical [H
1
]:
The slot of the bushing (if present) and the clamping hub must be flush with the groove (if
present) of the motor shaft; see Table "Tbl-10".
For the version with
clamping bolt, centrical [H
2
]:
The slots of the bushing (if present) and clamping hub have to be aligned with the keyway (if
present) of the motor shaft and rotated 90° from the clamping bolt, see Table "Tbl-10".

No gap is permitted between the motor [D] and the adapter plate [B].

Apply threadlocker (e. g. Loctite
®
243) to the four screws [F].

Fasten the motor [D] onto the adapter plate [B] with the four screws. Evenly tighten the screws
crosswise with increasing torque.

If the gearbox is a single-stage gearbox (MF1) , coat the clamping bolt [H] with threadlocker
(such as Loctite 243).

Tighten the clamping bolt [H] of the clamping hub [C].

The value for the tightening torque can also be found in Chapter 10.1 "Specifications for
mounting to a motor".

Screw the locking screw [A] into the adapter plate [B].

For screw size and specified tightening torque, see Table "Tbl-11".
5.4 Mounting the gearbox on a machine

Center the gearbox in the machine bed.

Apply threadlocker (e. g. Loctite
®
243) to the fastening screws.

Mount the gearbox so that the identification plate can still be read.

The specified screw sizes and tightening torques can be found in Chapter 10.2 "Specifications
for mounting to a machine".
