Those bearings are really common. You can get them make McMaster-Carr or Fastenal.
Whoever made that pusher tube should have cut the diameter down. You could have it 0.030" less than the axle diameter, so it's a sloppy fit.
The STEEL axle should a close sliding fit within the bearings.
I currently have the keeper bolt with washer as well; to keep the axle in place. I went by a machine shop today and he said my axle is a high quality alloy.
For fun, here’s a pick of my pusher rod stuck on the bearing. This is what was giving me grief. You can see the “tapered” end that slides inside my axle to help align and push it out.
Now I need new bearings so I’m on the hunt.

Maybe a thick wall 4130 steel would do the trick. You might need to get a smaller inside “keeper bolt” with thick washers. I did this to my Q when it was still a tail stagger. The keeper bolt that goes through the center of the axle might have been 1/4” or maybe 5/16”. It bares no load except to keep the axle centered. I had to cut mine out years ago also when still a tail stagger.
Glad you got the assembly off
Now you can beat on it on the bench and not wreck the wheel mount.
The idea of banging on that still inside the wheel pant gave me the heebeegeebees

Merry Christmas and Happy New Year!. It occurs to me that the issue may have been that the axle was slightly bent, maybe from a hard landing or other torque, so cutting it off was probably a good strategy regardless. Glad you got it out (or soon will) and will get your airplane functional again in the new year. Send us pics of your updated panel.
Christmas shenanigans got in the way until this morning and I was able to get it out….sort of. Freezing/shrinking didn’t work, tapping from all sides and techniques didn’t work, working lubricant in didn’t work, in the end I cut it off as close to the wheel pant as I could and was able to shove the steel push rod into the wheel pant enough for the tire to fall down and out.
Now I just have to take part the wheel and remove the bearing (which is what it is stuck on) and steel push rod and throw them as far as I can into the woods; never to be seen again.
Did you ever get that out or did Christmas get in the way?
Definitely lubricate it as you get it going
Hopefully the lubricant works it's way into the wheel
You may have to tap it back and forth a lot.....a little at a time, like rocking a stuck car back and forth

Maybe get someone to tap once on the outside and then tap the inside to see if that will loosen it. You could use propane to super freeze the tube and see if it can make it shrink enough to move it. Don’t smoke!

> Typos corrected: I’ve always had a bit of a headache removing the axle when needing to remove the tire. In one of the pics below, the darker steel rod is what I use to slide in and tap out the axle (which is the other pic). The axle will easily pull out from the position in the pic. However, the rod I use to tap out the axle is stuck and won’t move back out or further in.
