Bearing madness

With my engine out, of course I'll rebuild the TT. So I decided to take a look at bearings available online. Hey, I don't know jack about bearings, but I found a joint out in Cali that sells TT bearings (6006ZZ, double shielded, 16k rpm - I think that works) at 10 for $39.99.
Take a look:

I don't want to volunteer to organize a group buy....well not just yet.

I will indeed start a page on my site with a complete list of alternative bearings with some information on how to replace the throw out bearing and include various suppliers for each type.

The bearings that they sell are the brand names mentioned here and elsewhere. I say they are "good" wrt the fact that they are prompt, easy to deal with, and offer a wide range of choices, including ceramic bearings.

Considering the amount of work involved changing them, I'd rather spend the few extra $ on name-brand premium bearings for the torque tube. Ditto the alternator, torque converter, front wheel bearings, power steering and air pump. In fact I can't think of a ball or roller bearing in the car that I'd consider replacing with cheap. $4/each for name-brand non-asian/central American 6006 high-speed grade 6 or higher with high-temp grease, sealed and shielded (not just shielded) is an impossibly good buy. Advice-- confirm place of manufacture, and inspect the bearing for manufacturer's name before you buy. I've purchased bearing sets that were boxed identically but had all different sources inside. Kinda like buying the aftermarket motor mounts from Rock Auto. Ya just don't know what you are getting until you get well past the name printed on the box sometimes.

MAtt, I follow DR Bob on this one
$12 for 3 bearings is definately cheap, but if there is a known better bearing then i can certianly step up my budget. I guess in all honesty $12 is almost too cheap to justify the work involved in changing them.
I need to study the specs more and see what's best.
I was kinda jumping the gun because of brendan's post, but now that he clarified that good, is more to do with service then bearings then i want to take a look at some other options.

I'm with Dr. Bob on the TT bearings.
To big of a job to use cheap bearings with the risk of having to do it all over again.
My original bearings where made by *** Germany and marked 6006 C5 and had a metal shielding on them and clearly had leaked some grease over the Years.
(C5 is the bearing tolerance and I beleive they are a little looser than C1, C3 or nothing marked for tolerance, guess it is to compensate for heat expansion)
The best alternative i could find was made by SNR France and was rubber sealed and packed with a high temp grease 6006.FT150.
https://www.snr-bearings.com/catalog...l&id=6006FT150
Maybe the 6006.FT150ZZ is even better with a higher max rpm?
Just my 2 cents.

Easy guys not everyone is out there trying to rip you off.
I have been selling the best quality SKF TT bearings for less than $30 for a while.
I can buy the lower quality ones for $3 to $4 each at wholesale - is it worth it?
I have helped people out with Flappy Bearings - best quality for less than $15 each.
I will put a list of your part numbers and some prices together.
I buy in bulk and can still make a margin and sell to you at a reasonable price - My kids do need shoes

Note about the fan bearings above...
928ntslow figured out that you don't even need the spacer with the later clutches. The clutch axle has a step where it goes through the inner bearing, and the nut holds it there. Essentially, the inner bearing acts as a thrust bearing.

If Roger has done the homework, I'll go to him and pay for the expertise. Cheap luxury to get it right.

^^^^^^^ agreed ^^^^^^^^^^
So how big of a pain in the *** is it to replace the bearings in a TT and do the work yourself as opposed to getting a rebuilt TT?
Dan the pod man, was it your site that has a write up for replacing bearings and the tool you need to rig up to act as a press? I think thats what i saw.

The ZZ in the part no denotes double shields (one on each side). Unless there's debris flying through the TT, the double seals will likely be fine (SS or FF IIRC). Your bearing supplier will remind you of which is which.
