I need grade 25 1/4" bearings, 50 or 100. What's a good place to
order from? thanks

Isn't there a "Bearing Engineering" in Emeryville? IIRC it's near the
I 80. There is also a pretty good LBS on Telegraph. (I forget the
name) I think it's < a block north of University, on both sides of
Telegraph. Retail sales on the west nside. Parts & repair on the east
side.
Good luck, John

Missing Link on Shatuck. I don't know what they have for sale.
Velo Sport moved from MLK to University at California. They only sell
loose bearings, not packaged.

I don't know any more, about 3 different frames worth. A lot of the use on

There are 'many' cup and cone hubs on the market currently. Many
people, myself included, prefer them.
IMO, sealed cartridge bottom brackets are a decidely 'mixed blessing'.
I will continue to use C&C BBs on my personal bikes as long as
possible.

I recently sent a 20 year old Phil BB back for rebuilding. It was about
1/2 the price of a new one. I'm still riding another Phil BB from the mid
70s.
Loose bearing setups are rather crude devices dependent upon the quality
and pitch of the threads on the shafts, how well the cups and cones are
ground and so on.
The tolerance of .0001 between individual balls would be quite large for
better quality sealed ball bearings but is not a big issue for loose ball
arrangements.
At the rotational speed of ball bearings on a bike, most people could get
by with sleeved bearings and not notice any difference. ;-)

Dear Ron,
Forget all that spoke-tension nonsense! A hub full of Babbitt metal is
the only way (patented!) to secure spokes:
http://i17.tinypic.com/53ruw3m.jpg
"In constructing the wheel the ends of the spokes are inserted into
the perforations of the hub and then the filling is poured in in a
molten condition, and adhering to the spokes secures them firmly in
place . . . The inner ends of the spokes may be roughened or serrated
. . . and these ends may be tinned, if desired, before putting them in
place, for the purpose of causing a greater adhesion between the
spokes and the [hub] filling; or, if desired, the spokes may be bent .
. . as an extra precaution against their working loose in the
filling."
http://i11.tinypic.com/4m8ldeg.jpg
You may wish to adapt my method for preserving the proper tune of
stringed instruments. Once the correct note has been achieved, filling
the peg-box with Babbitt metal should eliminate the need for any
future re-tuning.
Cheers,
Louis J. Crecelius

HOW TO MEASURE BEARING WEAR.
Noooooooooooooooooooo problem!
Compare the used bearings to a an unused bearing of the same batch.
The duller the used bearing, the more out of round it is.
Say, does anyone have the address for the roman stone ball machine

That last bit, regarding grease, is something easily overlooked, but
critical. I'm glad Sheldon mentioned it.
Also, if a bearing ball drops to the floor, just dump it, IMO (unless
your shop floor is atypically clean!).

Ozark is absolutely right here. I'll add the cleaning issue: it is
most important that everything be clean and as free of grit as
possible. You can look at the cones and cups, with a magnifying glass
if necessary, and verify their condition. You can't reliably do that
with bearing balls, because there's no way to know that you have
actually seen every side of each ball, since they all look the same.
Also, don't use grease from a tub for this, use grease from a tube or
grease gun, so you know the _grease_ is also clean and un-
contaminated. Tub grease is fine for lubricating screw threads, cable
guides and the like but not for ball bearings.

The molehills are getting bigger here. My point, quite simply, is a
recommendation to use Grade 25 bearing balls for their uniformity and
'roundness', replacing them routinely and *not sweating* the bearing
ball hardness/polish/etc. issues.
Like effective grease, good quality bearing balls are a cheap
commodity.

future projections and averages divided by murphy's law governs.
200s/300s wear the cones
25 rocket science chromium does not.
so go cheap-replace cones
go a couple bucks more for the topend 25s and save yourself time and
labor
unless murphy's law intervenes-which it does right?
but averaging on the long run IF you run long the expensive metal
standard not racing asphlat bike component is the best deal
I ahve an exception: pedals. buying inexpensive pedal then maintaining
is two for one on the next $$$ level up. but it diesn't look like your
getting more mileage tho slightly less overall friction from the $$$
pedals.

IME, if the bearing balls are routinely replaced during periodic
maintenance, the 'longevity' of the bearing balls is not an issue.
Grade 25 means uniform and 'round', making good bearing adjustment a
snap. For bicycle applications they are, or at least should be, cheap,
making routine replacement the sensible course of action.

IME, it just makes sense to replace the bearing balls during an
overhaul. At $0.05 (or less) each for Grade 25s, why not??? Sure, you
can pay more and, *maybe* get longer-lived bearing balls, but what's
the point? Instead of pulling 'em, cleaning 'em and putting 'em back,
just use new ones.

i'm simply saying that from an engineering perspective, it's pointless.
if the same logic were applied to frames, we'd replace them every 6
months in case of fatigue. but we don't do it because they're expensive
and we can see cracking with a naked eye. bearing ball replacement is
little more than "feelgood" in the absence of replacement of other
bearing elements also - with no visual feedback, we attribute other
presumed benefits.

well, i'm not an engineer like beam but i take it apart and put it
abck together X times.
with shimano equipment, wood or fl grease, and harris 25 rocket
science bearings coupled with a 'normal' preventive maintenance
schedule:
rear hub goes 2 bearing replacements per cone then the hub is worn out
after the second cone so 3 bearing repacks. HD commuting/touring-
shopping at 60-70 pounds rear rack.
the ritchey headset is 4 repacks new bearings-no visual wear on the
crown race
original BB's Harris 25's 5 repacks and worn out-15K miles?
P. wood and finish line cycle grease with walmart castrol marine
grease when the cones get rough.
I don't see any reason for cone replacement before at least 2 repacks.
is there friction gain over the repacks and no cone? not noticeable
compared to installing a caged bearing set after loose bearings.
i gotta go rebuild the rear wheel with a new deore XT following an
attack from THE FRIENDS OF LEMOND.

Geez, this seems bass ackward; why use cheap (less uniform and less

What do you think has a tougher duty cycle, a bicycle hub bearing or a
boat trailer wheel bearing? IME, marine grease, packed and priced like

bearings.

This is exactly why it makes sense to replace the bearing balls whilst
overhauling the component. A through cleaning means removing the
bearing balls anyway; instead of cleaning 'em, just replace 'em.

indeed. marine grease is ideal for bikes - the moisture resistance does
make a difference to bearing life.

there's some truth in that.
but the best solution is high quality sealed bearings. headsets, hubs,
bb's - in each instance where i have high quality sealed bearings, i've
had zero maintenance issues. avoid cheapo "low drag" bearings sold for
bike applications - their seals are useless and bearing life is
compromised accordingly.

IMO, buy Grade 25 bearing balls (for their uniformity and 'roundness')
and replace the balls when you overhaul the component. Grit is a great
cause of wear; thoughly removing grit means removing the bearing balls
and cleaning everything. Why not just replace the bearing balls at
that point?

like spokes and their resistance to fatigue being a function of material
quality, the same applied to bearings. you can give an inferior
material a "grade 25" spherodicity, but it won't last as long as that
made of superior material. without testing or metallography, you can't
tell the difference - all you can do is perhaps note whether the bearing
balls are "ep" or not. if you're cheaping out on material, you'll also
presumably be cheap on the extra machining required for that final
polish - but it won't be definitive.

it may be "nice", but as far as the races are concerned, the components
that really determine life in bike bearings, it's pretty much a
pointless exercise - won't make the slightest difference to whether they

rs-
track the maintenance with a log and repack in a year or two which
ever is convient.
300's will do it. with wood or finish line teflon at Florida temps,
occasional rain, the grease absolves and washes out so that after a
year its shot and into a grinding compound downward spiral.
Which is the problem, I'm told: dirt.
Beam sez spalling but the degrading takes place on a microscopic level
with the metal getting ground off not lubed with clean grease.
so if the bearing lacks ultimate rocket science chromium content
hardness like the 300's, the bearing goes out of round to ellipsoid
and instead of rolling, begins slamming around in there like a hammer
pounding the grinding compound, and less of it every day, into the
cone. bummer!
by the way, finish line teflon 'seams' to have an edge on procrastin
nation repacks with some impressive lube power at very low film
quantities.
that's a good link but it doesn't tell you what you're buying.
i can't compare caws I went to cartridge BB, haven't redone the asian
25 bearing headset with low chromium content nor the deore rear hub.
inbetween. I'll get back to you on it. I'll shout from the bypass!

So does it make much difference whether we use Asian bearings or what
Sheldon sells? I can't make microscopic measurements on bearings, but
the races/cones (when failed) are "naked eye" failures. I would think
that the bearings are so much harder than the races that the bearings
are always going to outlast the race.

Repacking bike bearings falls somewhat below rearranging my sock drawer on
the desirable activities scale.
I switched to sealed bearings on a lot of components years ago and never
looked back.
Campy Record/SR hubs are my one throwback. I love the look and feel of
them.
I had several front wheels that hadn't been repacked in at least 10 years.
They ran really smooth but I could hear the bearings loosely rolling
around because the grease was so old.
I had an envelope of 7/32" grade 25 chrome steel bearings that was about
25 years old. I cleaned the hubs and components with solvent and repacked
them with Park grease. After careful adjustment they were rougher feeling
than the old bearings. I checked out some new bearings from the pack with
a 10x magnifier and found organic looking rust trails on the surface. They
looked like tiny brain corals. Clean and rebuild a second time with new
bearings....
Morale: check the bearing first!

The wheel I did yesterday wasn't running smooth. There was no grease
left, and several the bearings had split.
Unfortunately, I did use grease from a new tub, applied with a
chopstick. I'll do the tube thing next time.
While no one would ever buy a bike these days without sealed bearings,
there are still a lot of older classics around that aren't sealed.

I need bearings from time to time, not a lot. One local shop had grade

I'm sure of it, but live on the other side of the country so don't know who they
are. Hit the phone book. Almost any city with any amount of industry has bearing

Which specific product from them? They have many and I would need
1/4" Grade 25 or equivelent, they have many types so which is best?

You can mix and match size to fill a minimum order...that said, I use the
1/4" grade 25 ball bearings the most since they're for the bottom bracket
area. The other size I order is for the Wheel bearings. If you can call
Bal Tec to place the order, they are more than willing to help. The min.
order is inexpensive. $15.oo and you probably have a life-time supply.
Here is their phone number (1-800-322-5832)
good luck,

I've used them for ball sizing and ball measuring balls - "They have big

Pull out your yellow pages tomorrow.

Check the yellow pages: Bearing Engineering has stores in Emeryville and
San Leandro, Kaman has a store in San Leandro too. Also, you can check
with Grainger, they have several outlets.
Bearing supply companies used to sell loose bearings in 100 pack paper
envelopes that were treated with a rust preventative, also 1000 pack
cardboard boxes.
Loose bearings in plastic condiment bottles may be coming from wholesale
bike parts distributors. Several LBSs gave me dumb or dirty looks when I
asked about buying bearings by the bottle.
Good luck,
Chas.

rei bearings! amazing.
we spoke on bearings several times with experience suggesting a grade
25 bearing was a duh 25 bearing. Visually 25s i n wide price ranges
are shiny and shinier like 8 then 10.
the loose screws 25 bearings are probably rei bearings-check the
prices!!
the harris bearings are rocket science bearings for BB ( ifn yawl have
a balla and cone) or HD rear hub for HD commuting/mitty racing/touring
or just for fun if you're into spending RSB's
at this time I have no way to compare the Harris 25 to the Loose
Screws 25 (maybe the bikepartsetc also-its a coastal port thing)
butbutbut each disassembly of the harris bearings was "do I need to
replace these, they look new"
while the cones (Shimano and Wheels) were degrading.
If the assembly is generic at $10-20 go for the asian 25s but if
you're repacking a $50+ assembly or in a headset where replacing the
bearing surfaces is a hassle then the rocket science bearings will pay
off.
On the other hand, just to screw you around here, frequent replacement
of 200 carbon steel bearings with woods or finish line cycle lube
could be easier on the bearing surfaces as the 200's are softer than
the 25's. maybe.
the 25 is a sphericity number for roundness not a hardness or wear
number so a 25 could be carbon steel but rounder than a 200 carbon
steel at much lower price.
which is a good reason to spend the extra dough for RSB-clears the air
without getting a degree in bearing science.
get sevral kinds and put them in the vise grips and file twice then
inspect with magnifier and bright lught?

bearings more usually fail by spalling, and that's fatigue. that is
related to high quality surface finish. "ep" [extra polish] bearing
balls, can have a much better life span because of it - that's a visible
difference you can seek for comparison.

Don't the races/cones die first usually from lack of lubrication or
water/salt seepage?

it's not usually lack of lubrication, but they do indeed fail first.
replacing bearing balls is a pointless exercise if the cones are not
replaced first.
water seepage/grit intrusion is another issue and will destroy any
bearing, regardless of quality.

I neglected to mention that headsets were the subject in my mind when I
wrote that hence the lack of lubrication comment (sweaty roadies in
particular vs. MTBers).

Wow, what a coincidence, I needed the same bearings today. I went to REI
and they sold them to me for 15¢ each. I don't know if they were grade
25 or not, but I suspect that they were.
Loose Screws is a good on-line source for that sort of thing.
I often order stuff from McMaster, and they have them too, as someone
else pointed out, 100 for $4.12 which is a good price.
Most bike shops will have these and will sell them to you.

Usually I try to put together an order of $25 to 50 bucks so the
minimum shipping charge doesn't take quit such a large percentage of
the total. I prefer buying online for bearings because there is no way
to know for sure if they are 25 grade. I figure that neither the LBS
nor the on line supplier is likely to bother to switch lower grades on
purpose, but it is very easy to accidentally switch them. It seems to
me that the less they are handled the less chance of mixing.
Also the business of not mixing batches of bearings due to different
diameters. How in Gods name does one know if they are from the same
batch even if they are in the same bag? I suspect that there are a lot
of high mileage bike bearings out there that have mixed batches &/ or
grades. I guess what I'm saying is that I buy gr. 25 batches of
bearings w/ hope they are more likely to be a matched batch & actually
gr. 25 bearings.
I like BikeToolsEtc due to their location (usually 1 day shipping, UPS
Ground),
no sales tax for Calif. & their great customer service. I support Bike
tools etc. in particular because they provide a much needed connection
to unusual bike tools & parts @ one location (& 1 shipping charge). I
also like McMaster-Carr. I could get lost in their on line catalog for
days. I've never bothered to compare prices.

You touch on some good questions. I didn't like the answers either years
ago when we changed to our present vendor for American grade 25
certified chrome steel balls. We don't pay any extra for packaging so we
take them in 25-ball sealed packs. (1/4"; some other sizes in 50pk)
Beats the heck out of trying to maintain a 'purge' routine through the
shop every time we open another sealed kilo of balls and then wonder if
some wiseacre dropped a used bearing in the container. . .
I believe most vendors sell sealed prepacks now. If some guy is counting
out ball bearings one at a time you are definitely operating on trust.
Which may be well placed. Or not.

The yuppie trap L - BS near me sells grade 200 in packs of 20 (yes, twenty) for
$3.95. Of course these are the same jack holes who said that they don't carry
rear der hanger bolts without the hanger, "bring in the bike and we'll order you
one."
Anyway, the point was, go to the real bike shop, not the one with the huge
brightly lit sales floor.
