Right! Unscrewing you may collapse the frame in two small parts. The pitfall is 
the measure of the bolt and nut... A 12 mm diameter bolt, needs a 19 mm tool to 
loose/fasten and you'll need two tools, one for the bolt head and the other to 
the nut. As the bolt don't turns (it is a static axle), there are no 
self-loosening troubles, but for safety, I've used a "Parlock" type nut (a nut 
with an internal nylon ring which locks the thread).

If you want to know more about the angular contact ball bearings, go to 
http://www.skf.com/ -> Products -> Interactive Engineering Catalog -> Rolling 
Bearings -> Angular Contact Ball Bearings. They have drawings, calculation 
abacus and lots of good information. See below another draw about these 
bearings...
