SKF does make reliable bearings, i.e. manufacture bearings, not just import and distribute bearings.

That Z designation means the bearing is enclosed on only one side and with a steel shield. ZZ means a shield on both sides.
There are shields and then there are seals - different.

Finally online I saw the characters that prodded my memory when I saw them: 2RSH
That is 2 Rubber Seals. (H? I don't know what that's for).
I always buy the bearings closed on both sides with rubber/polymer seals: So 6302 2RSH if it is an SKF. I don't play with opening them and adding extra grease. The set I have in now were installed in 2014, used under Canadian weather conditions.

This site has excellent information on the designations; easier to digest than the official SKF site.

I know about the z or zz .The ones i have ordered has a picture showing that they have metalshield on both sides even if they are named with only one z hope they just named it with one z by mistake.
the genuine yamaha rearwheel center bearing has only 1 z  6304Z but has metal shields  on both sides if i dont remeber wrong?

Yes, SKF are top-quality bearings. You won't any problems with them.

Whenever I replace a bearing, I always use the -2RS (rubber seal, both sides.) Yamaha used shielded bearings (Z or ZZ) because they are a few pennies cheaper than the sealed bearings. And if you're curious, the letter after the -2RS denotes the type of rubber used. Sometimes that matters. In our bikes... not so much.

So then i learned somthing new today too i always tought that the bearings with metalshields was better sealed than the rubbershields ones after all some are used in washinmachines

A lot of parts websites just repeat a similar "close enough" looking image to save time and some file space. 1000's of line items adds up to a lot of hours of web building time. That could explain the discrepancy. Another reason to support local outlets or at least mix it up once in a while as to where one buys things.

I was told to use NTN as those were the originals. Also cheap, I think definitely less than 10 USD for a piece if my memory is right.

The bearings arived in the store for me to pick up some days ago and they had metalshield on both sides but they where named FAG
not skf. By that time i had done some more investigation about the metalshielded  and they are not sealed against water and dirt so i
asked if they could send them back and if i could make a new order (they had same price by the way) on skf bearings with rubberseals.That was okay with the store.

The original bearings in my USA '84 were Koyo.

Koyo, right, my mistake!

I've put Koyo, not NTN.

This was informative!
But I still have a few questions..

I have 2 SKF 6302-2RSH, and it looks like they go to the front. Right?
Then I have 2 SKF 6304-2RSH, looks like it`s rear center?
Then 1 SKF 6305-2RS1, dos it go on my -87 FJ1200 anywhere?
Then I have 1 KOYO 32006J HI-CAP. Is it useful for my bike?
Then I have 1 MBS 32005X, or is it SX? Is it useful for my bike?

Appreciate good answers. The season is about to start in northern Norway..

Hei Hasse og velkommen til forumet ! Kjekt å se en nordlenning her  prøver å svare deg jeg

Then I have 2 SKF 6304-2RSH, looks like it`s rear center?
Yes but in a partscataloge https://www.cmsnl.com/yamaha-fj1200-1987-1tx-europe-271tx-300e1_model37295/partslist/0031.html i seen they are different  one outer on brakeside has rubbershields and the next nr 4 in illustration has one metalshield (Z)
don't think it matters if you use the rubber, but I'm not 100% sure i think i remember that the flange NR 3 in illustration will push on the rubber or something
Then 1 SKF 6305-2RS1, dos it go on my -87 FJ1200 anywhere?  This one goes in the rearwheel hub carrier outer left  in the catalogue it has metalshield but rubber has better protection against water
Then I have 1 KOYO 32006J HI-CAP. Is it useful for my bike? This is the lower steering stem
Then I have 1 MBS 32005X, or is it SX? Is it useful for my bike?  This must be upper steeringstem but not sure it fits

Appreciate good answers. The season is about to start in northern Norway..
