To attach the motors properly and safely to the machine, Rexroth recom‐
mends the following screws and washers for attachment.
The screwed connections must be able to take up both the force
due to the weight of the motor and the forces acting during opera‐
tion.
In the standard case, use cylinder screws DIN 912 - M... x ... - 8.8 and corre‐
sponding shimmings according to DIN EN 28738. Some motors do not need
any shimmings. See table.
If the screws and washers used do not comply with this recomm‐
dation, the stability class of the screws and the hardness class
must be equivalent in order to transmit the required tightening tor‐
ques (see

MKE motors are designed for flange assembly (B05). Details on the mounting
holes are given in the corresponding dimension sheet. In general, the follow‐

Prepare the motor assembly as follows:
1. Procure tools, supplies, measuring and test equipment.
2. Check all components for visible damage. Damaged components may
not be mounted.
3. Ensure that dimensions and tolerances on the system side are suitable
for motor attachment (for details, see the dimension sheet).
4. Inspect all components, mounting surfaces and threads to ensure they
are clean.
5. Make sure that the assembly can be carried out in a dry and dust-free
environment.
6. Make sure that the holder for the motor flange is deburred.
