2x KBC 6205-2RS $3.72 each
1x SMT 5205-2RS $13.84 each
1x seal 32x52x7 B $3.50 each

shipping: $4.05: total $28.83.
Can't recommend the owner, Steve Stormont enough, answered lots of e-mails. KBC is korean, I've used them on many bikes. SMT is Japanese.

You've installed them and you are good to go? And which bike do you have (model/year... there is some variance)?

I have a 2004 SXC but the wheel in question is a cush 2001 LC4e. Yes
good to go. It's all standard stuff. Plenty of people have used 5205-ZZ
and posted about it, no rocket science.

Is the sprocket carrier bearing the same OD as the 6205 wheel bearings... 52mm? (bike's not handy to check).

I can't get a 3205 or 5205 here. Can get a 4205 though: 25x52x18. [edit]4205 is wrong, see later post.[/edit]

The bearing CAN be sourced from bearing suppliers. Here in Australia the bearing suppliers unit is half price of what KTM are asking. Mine collapsed somewhere between 36k and 40k (and took the chain with it ). Not a cheap exercise that one. The bike still rode fine, funnily.

[edit]
WRONG!!! The bearing is actually 25x52x20.6 (angular contact ball bearing, double row, seals on both sides)... likely an SKF "3205 A-2RS1/MT33", should be available, will check on Monday.

The product lists I was reading previously did not include the angular contact bearings.

It is NOT an SKF 4205 ATN9, a deep groove ball bearing double row
[/edit]

So it looks like the first digit of the code can vary depending on the market/supplier, as someone alluded to earlier. In this instance, it could be a 3205, 5205 or 6205 !!!

no!!!!! bearings come pre packed with a sufficient amount of grease. packing in a whole whack more could cause an overheating condition and failure. you may get lucky and heat the bearing up resulting in liquid grease pouring out... but the result will be similar... no grease... you will likely have a failure.

To get good high speed bearings try an independent alternator rebuilder. Even small shops like mine have over 100 #'s in stock. Most cost $3-$8.
I have never seen a wheel bearing # I didn't stock.

Guys, I am an idiot but I pulled my sprocket carrier bearing cause it was running rough, after I knocked it out(propane torch to heat gently), I washed it out after popping the seals and then packed the piss out of it(basically filled it full, left some small room for expansion) with the above grease(I packed every other bearing on the bike with this same grease, swing arm, steering head, all wheel bearings-front and rear wheels, pivot, etc.) I even put some under the front fork trash seals ala Creeper...then I rode the bike to Seattle, shipped it to Russia rode to Mongolia(Gobi desert for two weeks, temps around 110F.) and then to Europe. Around 10K miles was gravel sand dirt.

My sprocket carrier bearing still runs rough, I plan to repack it this winter. For now, still the same grease.
When I left for Seattle miles were 14K, now 35K or more.
You will not liquify this grease, it is designed for disc brakes running hot.
Pop the seals with a pocket knife. Just do it.

Ok, an update.

KTM specifies a 3205B-2RSR. The one in my bike is one of those (I think, the top half of the writing is rubbed off) but it also has "6205 RSR" in big letters on the bearing seal.

FAG/INA do a 3205-B-2RSR-TVH. Talking to my SKF chap, he says SKF are replacing all the "B" series with "A"s, only very minor differences between the two. So the SKF equivalent is 3205 A-2RS1, A for Angular contact.


If I was in the USofA I'd just buy them from Stenhouse Racing...

[bmwktmbill]

This friggin question won't die, to my mind only FAG makes the correct bearing, I bought a spare to carry just for that reason...when I checked with Colin@Stenhouse he was not selling the FAG bearing.
Maybe he is now.

I replaced my sprocket bearing eons ago with a NSK unit that I picked up at bearing supplier... The # on the box is 3205B-2RSRTNGC3....

Most of the answers to my questions were earlier in the thread. Dunno why I missed them

I know for a fact that Loaded specializes in pre-lubed fagina bearings...
