Front (original) wheel bearings for 3/4 and 1 ton Chevy.

B-46 ------- 1.4995 --- 3.1500 ---- 1.2360 ----------------- .8510 --------------- .9170
B-45 -------- .9058 ---- 2.2503 ---- .8000 ------------------ .6900 --------------- .6590
'46 to '52
B-26 ------- 1.4060 --- 3.1500 ---- 1.2260 ----------------- .8510 --------------- .9170
B-25 -------- .8435 ---- 2.2503 ---- .8000 -------------------.6900 --------------- .6590

Unconfirmed yet somewhat possible standard off the shelf bearings that might swap with a little work

The short answer is nope no one sells one,
the tricky part is at least on the 51 the spindle isn't a size that is used on standard bearings.
You can get around that problem by making a bushing or sleeve, not hard to do if you have a lathe or a mill.
The other thing to consider is how the seal will fit.
Can be done with just a little machining.
The good news is the cups that fit in the hub are a standard size.
Maybe Whitedog will chime in with some timkin numbers.
I used 1280/1220, 2788/2720 and 55x80x8sbrm.
That will get you in the right neighbor hood in the timkin catalog, then it's measure and pick one that will work for you.

You could swap to the 53 and later spindles and they do make bearings for those. (or keep your spindles and make bushings to adapt the outer bearings to them)

Yep Grigg
That's what I did used a bearing with larger hole and made bushings, same thing for the seal to ride on.
Some day when I have more time will figure out the best combo and maybe make a kit for people.
Something only a 3600 or 3800 owner would even think to produce

But have you seen the roller bearing kits the vendors now offer?? I linked to them a couple times above.

Lucky devils with the 53-59,
not a bad price for that size bearing either.
about the same dimensions as the ones I used, the thin bushings for the outer bearing were a bit tricky to make, would use a larger bore to have a little more meat to work with.

Another option for the inners would be to use 26877/26820 or 26877/26824 inner and have your spindle machined down. You could leave a lip for the seal. Timken 472446 should do the trick. Of course there's always the outer bearing issue.

There's always options when it comes to bearings, it just matters if you want the headache and expense of a machining your spindles. Personally, I would stick with a stock type bearing like the MBS rolers or an OEM Ball. If you ever chunk one and need a new spindle. Maybe it's time for the machine shop then.

Hello, I'm new to the forum starting today. I have a 1952 3600 Chevy. I was having trouble finding inner wheel bearings for my truck. But I found them last week at "locate ball bearings.com" $31.51 for the inner bearing. Plus $15 shipping. As long as you have your part numbers they can find it. Just thought I would share the info.
