This may have been discussed before. On an old rear Campy Nuovo Tipo hub,
that has 1/4 in. 7 ball retainer type bearings, I can fit 11 loose balls
leaving a little slack. Any advantages or disadvantages? It would seem that
the load carrying ability would be increased, but maybe it's negligible.
Anyone have an opinion? Thanks

In the "old" days that was SOP to replace with no retainer and more balls.
Rule I think is to fill the race with balls and remove one."Neptune" <[email hidden]> wrote in message

You don't want them to touch, they will kill each other. When you put
in the axle and adjust, they travel 'up' the cup a bit and it'll be too
tight in there with 12 balls. -

it's fine - go ahead and do it provided you don't over-fill. as you
suppose, there is a small theoretical improvement in load capacity and
it's common for different manufacturers to use caged and uncaged
configurations. caged sure is a lot more convenient for manufacturing. -

He meant to type "remove the cage and ADD one additional ball bearing".
What the original question asker wrote does not make sense. There is
no way you can remove the cage and add four extra ball bearings of the
same size. There is not that much extra room. Maybe he is replacing
the 7 1/4" bearings with 11 3/16" bearings. Or maybe he mistyped and
his rear hub with the cage has 9 1/4" bearings in the cage and he can
fit 11 1/4" bearings by making them rub against each other. That is
probably true. 7 bearings on the rear hub seems a bit too few. -

No, he said, more or less, "remove the cage, add as many bearings as
the race will hold, then remove one."Cages can be constructed so as to use as few as 1/2 the full capacity
of the cage, but most I've seen seem to be about 3/4ths. Only adding
one might be the case in some circumstances, but not always.Oh, and you don't actually "add" any - you replace them all, using more
than had been there with the cage. Mixing old and new bearings isn't a
good idea unless you're forced to on the side of the Dawson highway or
something. -

You don't want them to touch, they will kill each other. When you put
in the axle and adjust, they travel 'up' the cup a bit and it'll be too
tight in there with 12 balls.Loose balls are going to touch anyway. Having to many is an other problem. I
don't remember how many I have in mine, but I have no problems with it. -

spreads them and gain more clearance as the move up the cup. Touching
doesn't hurt, it is sliding under pressure that might cause drag. If
there is insufficient clearance for that number of balls, they will
lock up when adjusting the cones, so that takes care of itself.Good bearings use a cage only for assembly purposes while cheap ones
save cost by fewer balls and easy assembly.Jobst Brandt

bit too few.You have never seen real cheap hubs, I take it. They use a cage with
widely spaced balls, (as few as five). I also don't think Campagnolo
ever made hubs with that widely spaced balls but there are such hubs
on the market.Jobst Brandt

The rule is to _overfill_ the bearing race and then to remove one ball
bearing. At least, this is the rule with headsets.- Don Gillies

Rule I think is to fill the race with balls and remove one.Your hub left Campagnolo with nine 1/4" balls on each side.
The retainer is from some other application. Campagnolo hubs did not use
retainers before the 2000 model year--
