it's seized because i can see rust even from outside.

try turning that bolt several times before pushing it out with a punch and heavy hammer.

it's just seized.

have you tried spraying with lubricant overnight? penetrating oil is good.

find a strong socket for that bolt, then an extended handle where you can gain more lever. it has to turn, there's no way it can't.

Difficult to add to what Sleepwalker has already said but just in case it helps.....

You say you have already loosened the NUT. Which end did you turn to loosen the nut?
The nut shown in your photo is a special cam adjusting device (cam washer is welded to nut) which permits geometry to be set by turning the nut, which reacts against the two metal abutment walls also seen in the picture.
I suspect that you have just managed to turn the NUT rather than the BOLT.

Using a single hex socket (gives better engagment than a 12 point, so will reduce the risk of damage if it is really tight) undo the BOLT (end not in the picture). The nut has a convential thread so you will need to turn the BOLT head anticlockwise when viewed from the head end.
Once you have managed to turn the BOLT there should be no great difficulty in getting it to come out with the help of a hammer and drift, since any corrosion between the bolt and the inside of the rubber bush tube will have been broken.
If its very tight get the penetrating oil out and leave for an hour or so before attempting again.
If you are still stuck get an impact tool (like they use on road wheel nuts at the tyre shop) to encourage the bolt to turn.

If you really can't get the bolt to turn you are going to have to drill it out.

Good Luck.
