I had the idea to put electrical heatshrink around the bearings. I found one case were a person tried it, they said the issue was that the shrink moved around on the bearing as his shrink wasn't wider than the bearing so the plastic didn't go around the edges of the bearings and didn't holding them in place.
I have a dumb question for my first post on this forum. Instead of trying to wrap the bearing surface, how about applying a strip of PVC electrical tape to the extrusion surfaces that the bearings roll on? If it is durable enough, it could address the extrusion wear and possibly the metal-on-metal noise issue as well.....
