Application Notes
Rexroth IndraDyn A
The machine elements to be driven must additionally be secured in the
axial direction via the centering hole in the front of the shaft.
Note:
Avoid strong reversing operations. Deformations to the keyway
can lead to breakage of the shaft.
The motor is balanced with a half key. The mass relationships are similar
to those for a plain shaft. Inserting a complete key results in an imbalance
that must be compensated on the machine element that is to be driven.
The hub of a machine element that is to be driven (pinion, pulley, etc.)
should correspond to the key length.
Note:
If the hub is shorter, use a graduated key.
The motor is balanced using the included key. Hence, the machine
element to be driven must be balanced without a key. The keyway length
in the hub is independent of the length of the key.
Modifications to the key may be made only by the user himself
and on his own responsibility. Bosch Rexroth does not provide any
warranty for modified key or motor drive shafts.
Output Shaft with Seal
If the IndraDyn A motor is ordered with the optional radial shaft seal
according to DIN 3760 – Design A, they can be mounted to transmissions
with oil bath or circulating-oil lubrication, applied dusty environments, or
operated in moist rooms.
Note:
In case of open, oil-lubricated gearboxes, excessive mist or
speeds above 4000min
-1
, we recommend an additional
labyrinth sealing which can be ordered and retrofitted as an
accessory (refer to Chapter 7 “Accessories”).

Radial shaft seals are friction seals. Hence, they are subject to
deterioration and generate frictional heat.
