5.3.4 Axial and radial forces
You can obtain the permissible values for axial and radial forces by contacting the Siemens
Service Center or referring to the machine catalog.
NOTICE
Damage to bearings or the shaft
Large output masses and their centers of gravity outside the shaft extensions can lead to
resonance in operation. This can result in damage to the bearings and shaft.
Ensure that the permissible loads for the forces on the shaft extension are adhered to in
accordance with the catalog data or configuration data.
5.4 Cooling water supply for machines with water cooling
Seen from the shaft extension, connection of the water is possible from the right and from the
left.
NOTICE
Cooling water connection pipe
If the cooling water cannot flow freely, the machine will not be cooled properly. The machine
will overheat, which could result in material damage or even a write-off.
● Remove the flange cover plate.
● Insert the gaskets correctly.
1. For the pipes, select materials with the required chemical composition in accordance with
the water conditions. Also consider the pressure load and compatibility with the materials
from which the cooler is made.
2. Route and support the water pipes so that the connecting flanges are not exposed to
excessive stress or strain or vibration loads.
3. Rinse out the water circuit before you connect the cooling water supply to the motor. This
removes deposits and foreign bodies so that they cannot make their way into the cooling
circuit.
4. Should there be a possibility of the cooling water containing dirt and foreign bodies, install
suitable filters in the cooling-water feed pipe.
5. Connect the cooling circuit to the machine.
