Campy Scirocco-new axle little thinner-play

Hey guys, I had to get a replacement rear hub axle for my wheels (messed up the freehub side, not related to this issue).

The replacement axle gave my rear wheel about maximum of 1 mm of play. There is no way to get rid of it, given not crushing the bearings with excessive preload (radial cartridge bearings). I always set the preload with wheel in frame, turning preload collar until it stops and back off 1/16 of a turn, which always resulted in no play with the old axle. Axle is heavily greased. Bearings are new, NTN LLB.

When comparing diameter of old and replacement axle with a caliper, the new one is clearly thinner, about 0,005 mm.

As I previously owned Zipp 188 hub, they had similar Issue, due to axle-bearing clearance being quite big.

Is this a problem affecting riding or bearing life?

Thanks

Only you can answer whether it affects riding.

As to bearing life, the answer is no. Since the bearing is self contained, play between it and the axle won't matter.

In any case its easily fixed, if you're concerned.

There's a specific bearing grade of Loctite made for exactly this issue. It swells as it cures, filling gaps as it secures the bearing.

There are also various paint on products which you can use to build up the axle until the bearing is snug.

Which Loctite do you mean? Would the axle be removable? I know the 243 and 638 stuff, been using it a lot.

Anyway, please tell me more details or redirect me. I hoped a heavier grease will help, but not really, it gets squized out of the clearance anyway.
