are cartridge bearings better than well maintained loose ball bearings?
in hubs/h/sets, or are we just told that they are so that we throw away and buy new rather than service things.

cartridge bearings better than well maintained ball bearings?

yep, cos when loose ball bearings fall out over the garage floor...

No, they aren't any better.

Yes my view. better sealing and longer lasting. Would you want to go back to cup and cone BBs?
I have a mix of wheels and the cartridge ones all run smooth and last a long time, every time I check a cup and cone one its either rough or loose.

I think the key is 'well maintained'.
Shimano stick to cup'n'cone because they think it's a better solution engineeringly-wise for one, and like'em or loathe'em, they know they're bike stuff.
Personally I like the faff-free nature of cartridge bearings, plus they last ages (even in my non CK heaset Pete
) so they're not particularly 'throw away and buy knew'

Loose balls run as smooth and have less drag on the seal and are more adjustable/tuneable. The trick to this question was the mention of well maintained. I use king headsets, HTII bbs and hope hubs just because they're easier to live with. When the races die, the who thing goes rather than being left with a hub with knackered races.

All things being equal they're worse - having to have the extra bits of metal in the cartridge results in the balls being smaller than they might otherwise be.

You mean square taper ones? The sort which used to last for ever? Why on earth would you want to go back to that?

User error.

The square taper ones that lasted for ever were a cartridge unit. They may have had ball bearing inside, but they weren't servicable.

Old skool cup and cone BBs. Not cartridge square taper.
Not user error. I set the bearings up correctly. They will either take in muck and go gritty and tight / take in water and corrode and go notchy or wear to go loose over a period of time.
I can also change a set of cartridge bearings quicker should I need to.

My front hub is an 11 year old XT one and I think I've serviced it once. The loose-bearing BB on my commuter is about 30 years old and they are both fine, thank you.
Cup and cone is designed to take the slight lateral forces that wheels experience.

fella's, lets not argue about **** bearings, please.

I just checks a two year old XT hub. corroded bearings from the poor sealing, now will not adjust to be smooth and without play.

Cup and cone's fine, my Exages are cup-and-cone and are on (I think) their 4th set of balls, still going strong, and still spin far longer than my Pro 2s and DT240s. They go as long between services as any of my other hubs do, only difference is that the service is usually 10 minutes with some quality grease, rather than 10 minutes with some expensive new bearings.
Having said that, those are very good cup-and-cone hubs, the inferior Formula ones I had were a lot more hassle.

First time they've been serviced?

if you strip shimano cup and cone hubs when new, regrease them and set them up right they last a very long time. However, I run hopes on most bikes and they last very well too but they are noticeably more draggy than cup and cones set up perfectly.
Once again can I recommend Silkolen RG2 grease it is superb and very cheap in big tubs.

Cartridge ST are cup and cone - and there's a reason for that.

Depends on the hub in my experience. XT M765 and M756 are straightforward to service and keep just right, more recent versions of xt rear hub have been harder to get right and get moaned about a lot on here. (TJ, is yours a more recent one?)
Deore M525 good, but the cheaper M475 needs more frequent attention in my experience (probably the less good sealing). I have just serviced a set of old xtr M965 centerlok hubs for a mate and I may as well not have bothered; balls, cups, cones and grease all in excellent condition.I have had great logevity and service intervals with many shimano loose ball hubs BUT I couldn't get on with their 20mm ones which are also loose ball (in a plastic cage which you have to snap to remove and clean the insides
-I would steer well clear of these hubs, having had two that grumbled within a pitifully short time from brand new, and then would tighten up or loosen off within a couple of rides no matter what I did to them. I know it's not me as I have had no trouble with their qr hubs and will continue to buy them.

@aracer
I think he meant cup and cone as in serviceable. As far as I remember, they were/are not serviceable. None of mine were anyway.
Posted 3 months ago # -
I run loose ball hubs-on my commuter I've drilled the hub body to accept an oil can spout ALA the old Campy road hubs and they havnt been touched for 2 years continual all year round use, my Ragley has an XT rear hub that I've tapped to accept an industrial style grease nipple that I clip a grease gun onto every few months and pump a bit of grease through, Never any bearing or freehub issues.
Details are in a previous post of mine somewhere

I guess I am the only one old enough to remember servicing cup and cone BBS with screw in cups and a lockring.

Oooooh, the issue sideways forces/loads on conventional cartridge bearings versus angular contact bearings (as found in shimano hubs and some old ST BB's) is another issue I haven't heard argued about on here for a while. Probably for another thread though!
[edit] TJ, I serviced a bb like that last year on a 1985 Raleigh Record Sprint, and once I'd cleaned off the thickest grease I have ever found on/in a bike, it was all well shiny and smooth. (far better than the helicomatic rear hub of similar vintage!)

I've generally one answer to this. And the answer is Yes. Cart bearings ARE ball bearings, with precisely the correct tolerances and adjustment dialed in at the factory, repeatably and easily replaced by the end user and ensuring both races can be replaced should damage occur. There's no more friction than a decent labyrinth seal on a normal cup n cone arrangement and it removes all user error from the process. THAT is an engineering solution. As mentioned above, the side forces are better dealt with by shimano style bearings but cart bearings allow the bearing to be placed further out in the hub and for larger bearings to be used if required.
Just no contest in my mind.

Nope. I still have all the tools, and somewhere I think I've probably got all the bits for one. Doesn't mean that cartridge ST BBs aren't also cup and cone - if you're going to suggest that cup and cone are inferior just because they're cup and cone, then you're going to have to explain the important functional distinction between those in a cartridge and those you can adjust. Neither have races you can replace which seems to be the main (only?) argument I can see against cup and cone.
cart bearings allow the bearing to be placed further out in the hub and for larger bearings to be used if required.
You're going to have to explain that one to me. What feature of cartridge bearings allows them to be put further out on the hub than cup and cone? For instance on a Shimano rear hub, the right hand cup/cone is pretty much as far out as it is possible to go, and significantly further out than most cartridge bearing hubs (or all - anybody got an example of a cartridge hub with the main hub bearing at the right end of the freewheel, as I can't think of one?) Meanwhile, how does the presence of extra bits of metal making up the races of the cartridge bearing - which have to also fit inside the space which might otherwise be used for balls - allow for larger bearings to be used?

Correct me if I'm wrong, but don't cup and cone bearings eventually wear the surfaces the balls run on leading to hub replacement, whereas with a cartridge the same (equivalent) surface is part of the replaceable cartridge.

Somewhere in excess of 21 years, for me.
With some hubs, you can knock out the inner race and replace- the only thing that can be fiddly is finding a suitable replacement. I've done this with an old Shimano one, no bother. Wee bit more faff than changing cartridge bearings though.
Posted 3 months ago # -
OK I reckon 21 years, effectively makes me wrong.
Posted 3 months ago # -
To be fair, they were top kit and have been very well looked after. Not sure I'd expect the same from modern ones.
Posted 3 months ago # -
And after 21 years are the races work-hardened?

Something to be said for servicing an xt hub at the cost of 10p. Set of bearings for the hope pro II is about £20 isn't it? - LBS did one for me one time and charged me rrp of £45 for them! (accept that's on me if I'm getting them to source them).
Cartridges are probably better for me as I'm not that concientious at keeping on top of the fettling. If you run a tight ship I reckon loose bearings are probably better overall - at least in hubs where the service is easy.

I thought to myself before clicking this, TJ will say cart bearings are great, PP will pop up saying cup and cone is best.
Clearly I've read too many of these threads on here.
TJ is right btw.
Although I do have one of those^ bb's on my old roadie and it's great. I can't imagine the horror of having one on a muddy wet mtb though...

I find cup and cone well set up will run smoother, quieter and with less friction than the equivalent cartridge bearing. However, they are a pain in the arse to get perfect.
There was a reason that Campag stayed with cup and cone for years, and Shimano still do!

I still have that BB on one of my bikes. The one with 27" wheels and Weinmann centre pull brakes which I use most days.

Unless you believe your as good as SKF FAG/INA with tolerances and build quality of bearings, then go with cartridge bearings.
You will be able to get cup and cone hubs to function, but getting them to the same degree of performance as a good set of hubs running top end cartridge bearings would be quite hard if not impossible for most modern
cheap shitbrands.Posted 3 months ago # -
I can't be bothered to fiddlearse around getting the lock ring and preload set perfectly therefore cartridge is better.
