Where to buy quality wheel bearings in the US?

I need an unusual size for a RAD Mfg front wheel for my TR650...

ID=17mm
OD=52mm
thickness=12mm

RAD suggested I try All Balls, but they are closed for a week, and don't list this as an available size, anyway.

Any ideas?

Look up a local bearing house/supply store and give them a call.

Almost all my bearings(machine, car, truck bike, electric motor...) I get from(local to me):

Gopher Bearing Co

Address:
2490 West Territorial Road, Saint Paul, MN 55114
Phone:

Good luck. I spent three days attempting to find a non-Chinese bearing for my Elite 250.

This. Any town with industry in it will have at least one bearing supplier and all the ones I've used have been happy to deal with walk-in retail customers. Take the old one in and they'll hook you up with a good quality replacement.

I called a couple local places, and got "good luck" from them. Remember, this is NYC, haha.

The problem is, there is no old one. I'm replacing a busted cast front wheel with a spoked wheel from RAD. The axle is a weird design with a shoulder on the non-rotor side. I think the stock BMW hub must be narrower than the RAD hub, because the shoulder-part extends inside the hub. (I think the shoulder-part is there to remove the need for a spacer on that side.) The inside of the RAD hub is 52mm, while the inside of the BMW hub is 40mm, which is a more common size.
This probably doesn't make much sense without seeing it, though.

A 6203 is a common inexpensive bearing. 17mm ID x 40mm OD x 12mm W. Have a sleeve 40mm x 52mm machined and you're good to go.

Auto parts stores typically have a pretty good selection. But you have to find someone who is knowledgeable. The ones you listed are a weird size. 17x52x12. All Balls does not carry anything that size. Most of their bearings are Chinese bearings though they tend to hold up well.

I did find you spec in a 15mm thickness.

Auto parts stores (not the chains, like Autozone or Advanced, but the local guys), or industrial supply companies.

I usually bring my old bearings in and walk with new ones out. Simple.

I like SKF, and the store usually lets me sort through the bin to find one that is made in Germany. A lot of SKF stuff is now from South America and elsewhere. The German ones tend to hold up better to trail riding.

those dimensions are not listed on VXB.com

i don't think those dimensions are correct, I've never seen a bearing not listed at vxb.com

did RAD give you a bearing number? or just dimensions?

with that OD and width, vxb only lists a 28mm or 35mm id

with that ID and OD the thinnest listed is 15mm.

you have yourself a predicament...... know anyone with a lathe?

Did you try OEM??

Jeez, what a PITA finding those bearings.



How about through RAD??

http://www.radmfg.com/RAD-Front-Whee...dwk-huskyf.htm

WHY OVERSIZED BEARINGS?
The largest cause of hub failure is bearings going out and destroying the hub. RAD hubs are machined with an extra large center hole, allowing for a larger bearing with up to fivetimes the load carrying capacity of OEM bearings. This also provides lighter weight and greater torsional stability when landing big jumps in todays modern MX courses. Larger center race allows more contact between the spacers and bearings, which further increases bearing support and extends life.

RAD bearings are standard part numbers, readily available at all bearing supply stores.

most MX front axles are 20mm or larger.

That is the NY branch info. We use a NH branch at work.

But I'm with D.T., ask RAD .....

As of now, RAD isn't sure what I need to do. They said they've never seen a setup like this (which sucks, because they knew the wheel was for a TR650). As for the size... they were just guessing. The diameter of their hub is 52mm, and the diameter of the narrow part of the axle is 17mm, and the stock Husky (BMW) thickness is 12mm.
I don't know anyone with a lathe, and I'm not confident in my measuring capabilities to have a custom size made.
Thanks for the suggestions... I'm going to make some comparisons with the stock wheel and the RAD wheel and see if I can find another way around this, maybe with a custom spacer.
