Mac Guyver people! How do I find the right replacement part for the blower on my wood stove?

Our wood stove (made in china) has a cylinder shaped fan on it that moves the air through the stove. It’s shaped like the blades on this snowblower. https://thumbs.dreamstime.com/z/big-yellow-snowblower-cleans-snow-streets-city-146504823.jpg

We run this fan constantly. The fan works great but we need to replace the bearing that holds the other side of the fan shaft in place. That’s the part that keeps failing.

The first part actually melted through, so we don’t want to bother with buying a replacement from the company. I would like to find a permanent solution instead of having to keep reinventing the part. The part we used to replace it is a very small nylon bearing from the hardware store. We can tell from the sound of the fan that it will fail sooner or later.

The fan doesn’t get hot except for the constant rotation of the bearing at the end of the fan shaft. Maybe with the right bearing it wouldn’t get hot at all.

So my next question is what kind of bearing to get? I am guessing a very small shielded bearing would work, (it needs to be shielded because of dust). (See link) https://www.mcmaster.com/miniature-bearings/light-duty-ball-bearings/

Beyond that I’m not really sure what to get.

I’m also not sure how to go about securing it to the frame. Perhaps someone sells a bearing with a frame that can be adapted to my fan assembly?
