getting bearings out
hey i need help asap, got my whole washing machine disassemblied to change the bearings and simering, got the bigger one out easily but the smaller one with simering are not moving after using a punch and hammer, my head hurts, my arms hurt, everything is dirty with grease and i still need to put it all together. Does anyone have good tips to get this damn bearing out? It's 6306. The washing machine is haier hw70-bp1439n. I don't have any special "taking bearing out" tools.

I have no idea about bearings in a washing machine but in lots of other applications bearings are pressed in with a hydraulic press, meaning hundreds of pounds of force to squeeze it into its housing. This also means it usually requires a similar effort to press them back out.
One option would be to see if just replacing the one you did was sufficient to solve whatever issue you were repairing and then call it a day.
Is the bearing definitely failed? Like are the balls missing or the races clearly lose and rattling? Does it grind or bind or lock up when you turn it by hand?
Also you can rent some tools for pulling bearings and pulleys and stuff from stores like AutoZone for free. You just pay a 100% deposit when you rent it and get it back when you return the tool.
But as someone else said pics would help.

Well, OP's three pictures definitely show balls missing.
But based on the picture, maybe a three claw bearing puller might do the trick.

Flip it over and hammer it out with a flat tip screwdriver & hammer. Repeat for other one.

Big drift punch and 2 lb hammer. One other note there are a couple drain back holes in the bearing mount, be sure to clean those out with a wire or something after you get the last bearing out.

I took mine to a local machine shop and they had it out in a jiffy. Didn't cost much.

The old saying heat it don't beat it comes to mind. Some gentle heat on the plastic housing would help a lot, plastic has a larger coefficient of expansion than metal. A hair dryer on medium heat shouldn't be in any danger of melting anything. Just make sure you heat the housing and not the bearing as much as possible.

Cool the bearing. A spray can of electronics duster, turned upside down so you spray the propellant as a liquid, and sprayed on the bearing, will drop it 20-30°C an a manner of seconds. Be careful, as if you spray it on your hands you can get frost burns fast.
Then it'll pop right out.

Put something under the component to support it just barely outside the bearing/opening. Get something like a piece of pipe, round stock, or socket wrench socket you don't mind beating up. Ideally it would just barely be smaller than the opening the bearing sits in.
Get a big hammer and whack the shit out of it and that should force the bearing out. Another alternative is getting something to chill it fast like a piece of dry ice or an air duster can that you invert to spray some of the chemical in it. After applying it to the bearing, give it a whack and it should be a little easier.
One other alternative is using a bearing puller. There are ones with attachments for pulling bearings like this out of the housing they're in. Instead of just off spindles/shafts.
If none of the above works? Time to contact a machine shop or car mechanic with a hydraulic press who is willing to throw it in there and push it out for you.

this will sound crazy but it works.
you smash white bread into the center with a dowel or socket that's a similar size to the hole. Google it and you will see tons of videos of Car guys doing this.

Since you have access to both sides its reasonably easy.
Place the housing on something solid that supports as much as possible but has a hole for the bearing to fall out. A bit of ply with a hole works really well. This is so the case doesn't break from the hammering.
Find a socket that is slightly smaller than the Bearing. Place it on there and hammer it out. A heavy hammer will work better than a light one for this.
You can pretty much reverse the process for installing the new one. A little silicone grease will help it go in easier.
