Wheel Hub Question

[CTX-SLPR]

Howdy,



I'm not sure this is the exactly right subforum to put this in but a search for bearings seemed to localize to the Wheel section.

With modern sealed hub bearings like those found on the C4-C7 Corvette, 4th and 5th Gen F-bodies, and even the ZQ8 Blazer applications do the bearings get stronger when you run some form of stub through the middle of them like on an FWD/AWD or IRS RWD application? I know there was some discussion about not running rear C5 bearings on the fronts because they would pull apart or something. Is this largely superseded by improved bearing designs since the SKF C5/6 bearing can be run front and back with no stub for the fronts?

Just wondering,

Interesting question.
I don't have much knowledge on this subject but I'll add to the conversation anyway...

The older cars that use a bearing attached to the spindle, obviously they need the spindle snout to be there, because it has no other support.
On a C5+ application, the bearings are mounted solid to the hub, and the hub to the upright. So there's no need for a center piece (cv) to give it strength.
All of the C5 stuff I've seen and even the CTSV have a splined front hub from the factory, I wasn't aware that they used to not have the same bearing assembly (if that's what you're insinuating).
Having no hole or having a cv shaft inside of it theoretically would keep it from collapsing- but the loads on the bearings are more so lateral rather than radial.. So I don't think that'd help out.
It's my understanding that the ZR1 bearings are physically larger, so more surface area everywhere to help the strength...
I'm not an engineer.. Hope someone chimes in that is!

Also, not too sure why you have this concern. Lol.

I've been running the SKF front bearing in the front and they are fine...Although, I suspect that having a shaft in the middle might make them stronger, but I have no empirical evidence to support that claim.

Thanks guys,

Reason I ask is because of the weight of my '64 Riviera, I'm looking at bearings from heavy SUV's like the Jeep Grand Cherokee. The early WJ (99-04) 2WD had stub shafts in them but at some point they seemed to have stopped that. The WK (05-10) I can't find evidence that they had or did not have the stub shafts. The later WK2s (11-16?) don't have the stub shafts on the 2WDs.


I've been picky about getting a set from a 2WD with the stub shafts but it seems that they aren't really necessary.

Ok, heavily caveated question...

WITHIN A GIVEN BRAND, BETWEEN DIFFERENT APPLICATIONS
1. Is a more expensive bearing a higher capacity bearing?
2. Does a taller bearing IN GENERAL result in a stronger bearing?
3. Which makes a stronger axial load bearing, ball or tapered?

Thanks,
