Bent my 4th axle now, this one lasted just 10 days. I didn't even ride that hard just normal city stuff. I had changed the sealed bearings myself last year maybe that might have caused some problems. If I tighten the screws holding the axle against the bearings the wheel doesn't spin/ spins with too much resistance and if I loosen it a bit the wheel wobbles side to side. Is my hub cooked?

Ill go out on a limb and guess its freewheel equipped. The hollow axles surprisingly are more durable which might not seem the case. If you persist, then its not difficult to swap in a hollow one.
Yes. It’s cooked. Damn.
Get a new wheel.
It looks like an old solid axle, they generaly come with cup and cone system never saw them with sealed bearings, check for the quality of axles it s weird because old geniune parts are better than cheap fake parts, did happens to me on exercice bike that eats cup and cone bottom bracket i changed them oncd a week i tought i was doing some thing wrong , untill i returned to the original ones, so get a quality one or change the wheel all at once, used shimano wheels are better than keep changing parts
I would say your tyre pressure is to high for your weight.
If a tyre is over inflated the tyre does not deform to the bumps in the road, that stress is then transfered into the spokes, axle and bearings then stuff can break/bend.
The heavier you are the sooner you will break it.
Thw pressure on the side wall is your max pressure not your ideal pressure.
Replace your axle once more then try setting up your tyre pressure with this:

If you think its your hub look for any uneven seating when you put a new axle in with the bearings dry and hand tighten, it should feel like consistent friction when spinning if its straight.
Tightening the bearings on a hub to be the right friction/pressure is an experience thing and can be hard to explain/ find the sweet spot.
Maybe you need an axle like this,, look for the original axle

I m now conviced you did get the wrong axle, you style of axle in uncommun but it it exist you have a freewheel hub with sealed bearings, it looks like this look for the flat machined part of the axle where bearings is sitting

Is this setup as a singlespeed bike?
Check to make sure your hub axle isn’t broken.
Freewheel designs tend to do this. If you can find a chromoly steel or stainless steel axle, they tend to last longer.
Maybe it’s time to get creative with custom machined larger diameter axle and some cartridge bearings. Even a 10mm smooth axle made from a hardened bolt could do the trick and leave enough room for a 6000 bearing.
