JConcepts wheels for RC10 Goldtub
 

Offhand does anybody know what bearing sizes fit these wheels? The wheel part ref is JCAF and they are a 5-spoke design. The bearings my RC10 came with (fitted into the original 3 piece wheels) have an OD that is too big although they do fit B4 wheels nicely.

The wheels arn't made by JConcepts, they are JC Racing wheels ;)

The old alloy tub cars used to use flanged bearings, then from the B2 onwards they have been the same 3/16 x 3/8.

Hi, are these the rims? These are the JC racing ones - very happy with them so far.

Do note, however, that the offset is a bit different to those of your original wheels, and that the wheel wil run a bit closer to your a-arm than it had done. It's not so serious as to cause interference with most tyres, but if you have the stock arms and try to run a wide tyre like the proline wide ribs - you will have probs.

Yes, your old bearing is 3/16" ID x 5/16" OD with a 3/8" flange. The ones you need are 3/16" ID x 3/8" OD with no flange, as Richard pointed out.

I ran into this same problem when I was getting these new wheels for the RC10... If you'd like, I have four brand new bearings that would help you out. PM me if you're intersted.

Cheers,
Ty

Oops, quite right thats my inexperience assuming JC stood for JConcepts - I guess the CML branding all over the header card should have given the game away.

Tymill, you have PM.

Oh dear, the new bearings I got from Ty don't fit, not too bothered though as they do fit other cars I've got. I've attached a photo of the wheel with the wrong bearings to show the sizing difference.

Ideas?

You'll need the flanged ones for those then I think.

Yeah, Dan's right - sorry I didn't realise that your rims are different to the ones I have. It seems you'll need 4 bearings similar to the one shown sitting on the three-piece wheel in my photo. I'm not entirely sure where the best source for them is in the UK, but it seems you can still get them throuhgh CML:

Pricey though. Hmm.

The RC10 6-gear transmission is full of these bearings too, so they must be pretty common. I might have one or two extra used ones if you're really desperate to find some. Let me know.

Blimey those are expensive. Have a look here for steel or here for ceramics. He also does cheaper ABEC3 rated ones.
