(2) 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.
The HC-MF
HC-KF HC-AQ HC-MFS and HC-KFS series servo motor is not equipped with an oil
seal and cannot be used with the gear box as described above. Oil should be shut off on the gear box
side.
In a special specification article with an oil seal is available. Please contact Mitsubishi.
