Yes you'll get it cheaper . Bring the bearing it has name and numbers on it. Or it will be mesured. Bike part number won't help at a bearing supplier. Tell em sealed bearing

I dont have the exact price for the bearing you want (#3205) but seeing in the shop online fiche on here that they sell the others bearings for the rear wheel(#6205) for 29$ each US. I can have this bearing (#6205) for 3.50 Canadian...So Im pretty sure it can be found cheaper.

This place:

http://www.cbrbearing.com/

Has a large selection of high quality sealed bearings. They probably have the size you need. Take some measurements of it, or read the numbers on it, and give them a call.

They've done right by me.

As a note: do ask who makes the bearings you're buying. There is a big difference between a quality ball bearing and a cheap one, and there's no way to tell by looking at them. Truth be told, price is usually a good indicator, presuming you're getting them from similar sources (industrial supply places).

I can have a 3205 bearing for around 30$ Canadian. Just called a bearing supplier.

I went to a local bearing house and got one for about $35 IIRC. I don't think it was much over $80 or $90 for all of the rear wheel bearings

When you get the new one pop a seal off one side with a small screwdriver and pack the crap out of it with your favorite waterproof grease. That is a dirtbike trick to help seal out the water and crap.

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...

Righto, today had a little chat with the warehouse manager for a local bearing supplier; he offered these points:
  • Anecdotally, 90%-odd of bearings fail due to contamination, bearings put in water are the worst. The seals are not designed for water protection.
  • Bearings do have a limited life, and sealed bearings are lubed for their expected life. Once the grease is gone, the rest of it is in need of replacement, too.
  • Pressure washers and water crossings (hot bearing into cold water, sucks the water in as the bearing cools rapidly while immersed) are the enemy of long bearing life.
  • The rule of thumb for packing with grease is no more than 30% of the cavity. This is more than the manufacturers put in there, they are more exact. Any excess is pushed out of the seals.
  • If the excess cannot be displaced, then it creates friction (drag) hence extra heat which stresses the bearing unecessarily. If you want to pack the crap out of the wheel bearings, remove the inboard seal so all the excess can be displaced happily into the hub. [Which to my mind makes it a waste of effort]
  • Although they should be greased and not rusty, steering head bearings will tend to notch as they never turn a full rotation... another case of poor conditions shortening their life. Nothing you can do about it.
Given my wheel bearings have lasted 30,000km or so, my plan is to pack 30% grease in them every 5-10,000km, as the bike does a lot of water crossings.
