8.2.1 Removing/installing the motor
Removal
● When removing the motor, mark the original position of the components with respect to
each other (e.g. using a colored pen, scribing iron) to make subsequent installation
easier.
● Removing the encoder, see Chapter "Removing/mounting the encoder".
● Unscrew the NDE bearing shield screws and carefully remove the NDE bearing shield.
● Unscrew the bearing cap screws (see "Spare parts", item 1.02).
● Remove the grease slingers from the shaft shoulder (DE).
● Remove the rotors from the motor. Use a suitable device to remove the rolling-contact
bearings.
Mounting
● Do not reuse rolling-contact bearings that have been removed.
● Heat up the new rolling-contact bearings evenly to 80 - 100 °C and attach them. When
doing so, make sure that the bearing inner ring lies on the shaft shoulder.
● The device must not be subject to hard knocks (e.g. do not use a hammer etc.).
● Insert the motor rotor into the stator.
● Secure the bearing cap.
● Insert the NDE bearing (with shaft spring) into the NDE flange (keep the bearing straight)
and tighten the screws.
● Press on the grease slinger (gamma ring housing 9RB... without sealing lip) with a
suitable sleeve (dimension x = 0 mm (flush with cover)), see figure "Installing the gamma
ring". When disassembling, do not reuse damaged grease slingers.
With the bearing type "increased radial forces" (14th position of the Article No. = "F"), the
grease slinger must protrude 1 mm over the cover, i.e. dimension x = 1 mm.
