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 is required for an IP65 rating or greater.
IMPORTANT
The shaft seal is not required 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, as paint can decrease the life of the shaft seal.

Required Tools
Use these tools to install a shaft seal:
•
Insulated, small, flat-head screw driver
•
Rubber/wooden mallet or a metal hammer and wooden work piece
•
Socket, pipe, or tube (various sizes)
•
Abrasive cloth to remove any nicks or burrs from the motor shaft
Shaft Seal Kits for Kinetix TLC Servo Motors Installation Instructions
Required Supplies
Lubricant - Grease, industrial grade, suitable for applications with speeds up to 6000 RPM, and –10…+80 °C (14…176 °F) temperature range.
Remove the Shaft Seal
ATTENTION: To avoid injury or damage to the equipment, remove power from the motor before removing the shaft seal.
Follow these steps to remove the shaft seal.
1. Remove power to the motor before removing the shaft seal.
2. Remove the shaft key (if present) from the motor shaft.
3. Remove the old seal.
a. Place the insulated screw driver on the inside diameter of the shaft seal outer lip as shown.
b. Carefully lift the seal, work your way around the seal lift a little at a time.
c. When you can grasp the seal, slightly rotate it while pulling it out of the front-end bell.
ATTENTION: Avoid damage to the motor.
• Do not pry against front-end bell or shaft.
• Do not hammer the shaft or body of the motor when changing the shaft seal.
Outer Lip
Do not pry against front-end
bell or shaft.
Do not remove
screws.
4.
Inspect and clean the shaft and seal surfaces as necessary.
Use an abrasive cloth to remove any nicks or burrs from the motor shaft.
Replace the Shaft Seal
Follow these steps to replace the shaft seal.
1. Apply tape to the keyway so the edges do not damage the seal lip.
IMPORTANT
2.
Cover the sharp edges of the keyway with tape to protect the shaft seal lip from damage.
Lubricate the motor shaft and the inner and outer lip of the shaft seal.
IMPORTANT
Shaft seals require a lubricant to reduce wear. Lubricate only the inner and outer lip of the shaft seal. Do not lubricate the motor bore or outside
diameter of the seal.

Center the shaft seal on the mounting surface of the motor and slide the shaft seal evenly onto the motor shaft.
See Shaft Seal Installation Clearances on page 3 for the correct installation clearance of the shaft seal you are installing.
Press the shaft seal into the seal bore by applying one of the Shaft Seal Installation Methods on page 3.
Visually inspect for irregularities in the shaft seal or an uneven alignment where the shaft seal contacts the motor.
Verify that the outer and inner circumference of the shaft seal is fully seated into position.
Verify that the shaft seal is installed to the correct installation clearance.
• If the shaft seal is installed too deep, it can become 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.
For motors with a keyed shaft, replace the shaft key.

Shaft Seal Installation Methods
ATTENTION: Do not hammer directly on the shaft seal. Gently tap the socket, pipe, or tube evenly around the outer edge of the shaft seal until the
shaft seal is pressed into place. Make sure the socket, pipe, or tube you use does not contact the shaft seal lip. Permanent damage to the shaft seal
can occur.
