Technical Wheel Bearings by size chart / crossover

I’m looking for a good resource to cross reference tapered wheel bearing size and races. Or to look them up by sizes.
A2 A3 and that kind of stuff stuff.
Ive got pretty good google-fu but I can’t find much of anything in usable format. As usual I’m trying to put things together that aren’t supposed to go.

Thanks !

If it will load for you page 40 starts tapered bearings numeric listing, few pages before has some info.

 

It's go down that chart that JohnLewis posted and find the right OD of the outer race and ID of the inner race and go from there.

If you have a Ford spindle Ford used about two outer wheel bearing numbers for decades. Inners changed but outers didn't.
Chevy and GM spindles you have to deal with the shape where the spindle shaft meets the spindle body. It's a nice round radius that most other bearings don't have. Us Chevy truck guys fight that going from ball to tapered cone bearings on stock axles.

 

The odds of getting a counter person that’s knows this exists? Next to none where I live.

 

Thanks John, that helped a lot.
It’s was not easy switching pages from your link though. I’m not even sure I can remember how I did it.

On page 40 I found the OD “D” of an A3 set. 1.9687 .
On page 91 I found 3/4 bore with larger OD of 1.9380 and a jump to 2.215. WTF

I need a 3/4 bore in an A3 hole.

 

Yeah I use it on computers, I can never navigate it on my phone. Timken, SKF, Etc Do the same jump up in sizing in their catalogs as well. I assume its going on a spindle? I've seen them before but have you tried looking up spindle adapters? and just adapting it to use a A3.

 

Good info. Thanks! Love the HAMB!

 

I have the advantage of having managed for the company for 6 years. But I took a interest and pride in my work. Something lacking with people in parts these days. You would be surprised how much every company offers to employees other than a electric catalog that no one knows of or utilizes.

I think these should work outside of user login, more catalogs if you want to flip through them.

 

This is excellent stuff thanks!

 

Closest I can find is a Timken 07079-07196
https://fci.thomasnet-navigator.com/cache/Geomstore/20240426-112912-07047099.pdf Still A Bit Bigger Than 3/4 Inch Though

Timken 09078-09194 has your bore, but falls alittle short of the full OD. Also I think was alittle more width. Dont know how tight your tolerances are.

 

I always find a damn rabbit hole.
Why the part numbers are “set 1, set 2, 3 and on I’m unsure of. Set 3 is smaller than set 2 but why is a set 5 bigger than set 6. Baffling

The bearing guys created over size races to allow for retro fitting and repair of hub holes. But Purposely the bearing guys skipped a size that prevents a set 2 cone in a standard set3 race hole, just below or above on the over size races. The same thing on smaller set 6 to larger set 5. Just above and just below.
There Shall be no mixing without machining.
Speaking with Timken , we did find one really really close but from a different “series”. I said what’s a different series mean exactly? He said it’s designed for something else, not automotive/agricultural. Ok,,,
He said that was definitely specially designed for something heavy duty because the specs were 3x the set 2/4 rated, and it’s around $100 a race.

I’ve got another option but need to see if I can bore it .04ish bigger for readily available conversion bearing stuff.
I’m a little Leary because it has less rollers that a regular set2 cone does

 

.

@31Vicky with a hemi is this a specific application or something your building and trying to find a bearing to fit ?

...

 

Just a caution, make sure the original bearing sizes were inch. A whole lot of them are metric, even going back into the 50s.

Not necessarily wheel bearings, but then I have no idea what your working with.

 

Very specific, very problematic, ot
used to be OEM deal, last aftermarket production run was around 1992 and it was limited.
One outfit reproduced them around 2010 and stopped.
I’ve almost got a work around.
Spindle takes set 2&6 easiest if that stays.
New hub takes set 3&5 standard

 

Ah OK, been there before with the older ford truck import manual transmission!!
