Replacing retainer type ball bearings with loose
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 Neptune |

Replacing retainer type ball bearings with loose
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" wrote in message ... This may have been discussed before.

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. |

Thanks Neptune 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. |

wrote: He meant to type "remove the cage and ADD one additional ball bearing". 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. |

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. |
