2.4.3 Precautions for using servo motor with oil seal

This section defines the operating conditions for using the servo motor with oil seal:
2
1. In the operating environment, keep the oil level lower than the oil seal lip.
2. Do not submerge the oil seal in liquid. The oil seal can only withstand splashes of oil.
3. Do not soak the oil seal lip in oil.
4. Keep the oil level lower than the oil seal lip. If the oil level is higher than the oil seal lip, oil
may enter the servo motor and cause damage to the motor.

2.4.4 Precautions for using couplings

Caution:
It is suggested to use flexible couplings specifically designed for servo motors, especially double
spring couplings, which provide some buffer tolerance during eccentric motion and deflection.
Select couplings of appropriate size for the operating conditions. Improper use or connection
may cause damage.
1. Wipe off the rustproof coating or oil on the motor shaft.
2. If you use a servo motor with a keyway, install the attached key or a key matching the
specified dimensions on the motor shaft.
Note: when you install the key on the motor, do not apply excessive impact force to the keyway or
3. Use dial gauge or other methods to ensure the centering precision is within the specifications.
If you cannot use the dial gauge or other methods, slide the coupling along both axes and
adjust it until it does not get stuck.
