About Shaft Seals
A shaft seal is recommended if the motor shaft and end bell are exposed to significant amounts of
containments, such as oil, fluids, or fine dust. Use a shaft seal in these environments to prolong
the life of the motor. A shaft seal and Bulletin 2090 cables with environmentally sealed
connectors are required for an IP66 rating or greater.
See Kinetix® Motion Accessories Specifications Technical Data, publication GMC-TD004
find Bulletin 2090 cables with environmentally sealed connectors for your motor.
, to
The shaft seal is not recommended in applications where the motor shaft and end bell are free of oil, fluids, or
fine dust, and a lower IP rating is sufficient.
Shaft seals are subject to wear and require periodic inspection and replacement. Replacement is recommended
every 3 months, not to exceed 12 months, depending on use.
If you paint the motor, do not get paint on the shaft seal area or the shaft. This can decrease the life of the shaft
seal.

Required Tools
Use these tools to install a shaft seal:
• Rubber/wooden mallet, or a metal hammer and wooden work piece
• Socket, pipe, or tubing (various sizes)
• Abrasive cloth (to remove any nicks or burrs from the motor shaft)
Install a Shaft Seal
ATT EN TI ON : To avoid injury or damage to the equipment, remove power from the motor before installing the
shaft seal.
Follow these steps to install the shaft seal.
1. Verify that power is removed from the motor.
2. Remove the shaft key (if installed).
3. Remove the old shaft seal (if installed).
4. Remove any dirt or grease from the motor shaft and the area around the front end bell of
the motor near the bearing.
5. Use an abrasive cloth to remove any nicks or burrs from the motor shaft.
6. Cover the sharp edges of the keyway with tape to protect the seal lip from damage.
7. Lubricate the inner and outer lip of the shaft seal with the lubricant in the kit.
Shaft seals must be lubricated. Lubricant is supplied with the shaft seal kits.
8. Position the shaft seal so that the sealing lip faces outward on the shaft.
9. Slide the shaft seal onto the motor shaft.
10. See Shaft Seal Installation Clearances
the shaft seal.
11. Use one of the Shaft Seal Installation Methods
diameter of the shaft seal into the motor.
Verify that the shaft seal is installed to the correct installation clearance.
If the shaft seal is installed too deep, it can be subject to excessive wear and require frequent
replacement.
If the shaft seal is installed too shallow, it can reduce the effectiveness of the protective seal.
