Hi folks! I am looking for a ball bearing assembly that can be easily taken apart and re-assembled. I'm trying to test some ball bearings (the balls themselves) so its advantageous to have a housing that I can easily take apart and reload with a different type of ball without damaging anything. The best option I've come across so far is a cup/cone adjustable bicycle hub. Does anyone know of something similar to that, but as a stand-alone assembly? I've searched around google a bit but have come up empty.
