SiC Ring Outer Diameter 5mm 3 pcs

Please carefully measure the ring size of your guide. If the size is incorrect, it will not fit. If you can confirm the model number of the guide, you can determine the required size.
We offer rings in sizes 4mm, 5mm, 5.5mm, 6mm, 7mm, 8mm, 10mm, and 12mm. If you are looking for a different size, please check our other listings.

This is a SiC ring.
Please use it to repair a broken guide.
It can be attached to guides where the diameter of the ring's contact surface on the frame is 5mm.
Here's how to attach it:

1. Prepare the guide frame. The ring contact surface of the frame should be filed smooth beforehand.

2. As shown in the third picture, hold the ring vertically and try to see if it can pass through to the other side. Ideally, it should pass through with a slight push. If it doesn't pass through, file the frame with a needle file to widen the contact surface.

3. Fit the ring onto the frame. If it's tight, gently crush it with protected pliers to fit. (See the fourth picture)

4. Apply adhesive to the seam between the ring and the frame. Epoxy adhesive, which allows for some working time, is more suitable than instant adhesive.
Apply the adhesive to the tip of a needle or toothpick and coat both the back and front surfaces along the outer circumference of the ring.
A thin layer of adhesive is sufficient.

Please be aware that the ring can break if subjected to strong impact. It will break with a crisp crack, so be careful when fitting it with pliers. A set of 3 is included in case of failure.
You can also file the frame more to fit it loosely, although this will reduce adhesion strength.
If you use epoxy adhesive, it should not come off easily, so you don't need to aim for absolute perfection.

If done correctly, you can upgrade even inexpensive guides to SiC guides. If you are interested, please give it a try.
As this is a specialized item, please ask any questions you may have.
