Protection from oil and water
When the gear box is mounted horizontally, the oil level in the gear box should always be lower
than the oil seal lip on the servo motor shaft. If it is higher than the oil seal lip, oil will enter the
servo motor, leading to a fault. Make sure there is a ventilation hole in the gear box to prevent
any pressure build up in the gear box.
The following table presents an overview of the minimum clearances between the oil level and
the servo motor shaft centre:
Servo motor Height above oil level [mm]

CAUTION:
The servo motors in the HC-MFS- and KC-KFS-Series do not have any oil seal on the
shaft. Here the sealing must occur on the gear side.
