How to Remove Friction Rings from a Flex Shaft

If you’ve damaged your flex shaft and need to repair it, don’t worry—it’s a straightforward process. In this quick guide, we’ll walk you through how to remove the friction ring (also known as the sleeve bearing) from your flex shaft, so you can shorten the sleeve and get back to work with minimal downtime.

Step-by-Step Instructions

1. Cut the Damaged Section
Start by cutting off the damaged part of your flex shaft. Use an angle grinder to make a clean, straight 90-degree cut.
Tip: Avoid welding the shaft—this process is not necessary and can complicate the repair.

2. Remove the Compression Spring and Shaft Lock
Next, remove the compression spring and the shaft lock. These components come off easily by hand or with the help of basic tools.

3. Unscrew the Friction Ring (Sleeve Bearing)
Now locate the friction ring at the end of the sleeve. You’ll notice a small area where you can grip it securely.
You can use pliers for a better hold if needed. Twist the friction ring to unscrew it from the sleeve.

4. Adjust the Sleeve Length
With the friction ring removed, you can now shorten the sleeve to the desired length.

5. Reassemble
Once you’ve trimmed the sleeve, screw the friction ring back into place. Then reattach the shaft lock and compression spring.

6. You’re Done!
Your shaft is now repaired and ready for action again.

Repairing a flex shaft by removing the friction ring is a quick and easy process that doesn’t require any welding or specialized equipment. With just a few basic tools, you can extend the life of your shaft and save yourself time and money.
