yes and no.....thin plated bearings...gray bearings go with worn/used

hubs.



Grade 5 go with above average hubs or as new hubs...grade 5 runs new

longer than gray bearings.



The new ball bearings were very shiny when I put them in, and sort of
grey

when I examined them a few days later to see why the hub hadn't stayed

adjusted for long.



All the shinyness had become little shiny flecks in the grease.

cccccccccccccccccx

haven't seen that but my hubs aren't inspected at short run times. Use a
looser assembly tightness, red Loctite one side n blue ;lock the other
side suaully the drive side. Be very clean with paper towel thinner
cleaning, 2x...followed by CHOH cleaning of the thinner residue. Let the
assembly cure for 3-4 days in warmth/sunshine before using.

CBA with all that - as I've already used PTFE grease, threadlock compounds
wouldn't do anything anyway.

As long as the cones are set OK on the Freecycle wheel, I'll just stick it
in the bike and use it.

If it ain't broke, don't fix it.

That would be evidence for them being plated, not through-hardened.



As you found out, under stress, a plated ball will shed it's plating,

at which point it becomes birdshot in grinding paste.

The second bit is pretty much the same as my own opinion - the first bit I
what I said in an email to the shop I bought them from.

Several weeks later - still waiting for any reply.

I'd have thought it would be essentially impossible to buy soft but plated steel balls, when one asked for ball bearings.

Well, I've given a URL for the reputable supplier I use.
OK, the prices I gave were for bags of 500,

And I might have contacted them to place an order - but meanwhile I
scrounged a wheel on Freecycle.

If I get that desperate, I can rummage the junk box for motorcycle engine
cartridge bearings and find out which ones contain the ball size I need.

Then you'll probably get caught out just like I did.

If you've used soft plated balls a couple of times then tthere's a very good chance that those balls deformed and knackered the hub cups too. I hope that's not the case and that the installation, proper lubing of them, and the proper adjustment of the cones takes care of the problem of the cones loosening. BTW, you might want to check both tthe threads on the cones and locknut and the ones on that axle in case either are worn and thus not holding things tight after being put in use. Cones should not loosen in use and the facttthat they do is indicative that something is seriously wrong somewhere. You sure don't want to break an azle out in the sticks and have to walk home.

Cheers

Does someone actually make plated bearings for sale to the public?
My uncle worked at a bearing factory and he once mentioned that they
were making some gold plated bearings for NASA some sort of space
thingy, but I don't believe I ever encountered a plated "ball bearing"
for general use.
