They have been using substandard bearings for some time. The AX engines have been known to eat bearings. If you want to have trouble free high quality bearings, replace with Swiss made WIB bearings. They are fantastic. My Picco .28 came with WIB bearings and my Novarossi engines have Italian made bearings (Nova has a patent on many of their bearings due to an offset inner race). Ive used numerous cheap Chinese bearings that cost $1 each and haven't had any problems from them. They actually seem to outperform the OEM units they replaced (powerwise from the engine). Heavily loaded and high rpm engines should have a phenolic ball cage though..
