I think that’s what I’m going to end up doing - I can get 26mm and 28 OD bearings pretty easily, if I can find them with 12mm ID it should be easy to turn a sleeve.
Do you know, off the top of your head, if I remove the set screw from the axle if it will just slide out? Or is it threaded internally and the set screw is a rotational lock?
Ive never had an issue with the 10-pack amazon bearings. I always pack mine with white lithium grease. I like to change them out every 4-5 months, or more often when winter riding when they get wet so i refuse to buy expensive bearings
The axle is pressed in, with an additional set screw as safety. If you want to remove the axle you’ll also destroy the ID of the hanger bore, which is why just turned some sleeves instead of replacing the axle. Both is possible though.
It took a couple of tries but I managed to get a sleeve together. I also made it thicker to take up the excess length of the truck axle. Here are some pictures
That looks sketch, i’d prefer you get the correct OD bearing that fits into the hub perfectly, and then get a steel/aluminum machined spacer that is for the ID of the bearing.
The problem is the sleeves would have to be so thin (probably less than 020) and I can’t turn something that thin. The next option would be to remove the axle, press a thick piece on and turn it down, but I can’t remove the axle without a lot of drama.
These sleeves are Delrin, so super tough, so I think I’ll be ok. If not I’ll report back here from the hospital bed
