few questions regarding different bearings and their performance whats the difference between ceramic bearings and normal ones? konkave vs center trac vs normal bearings? difference between yyj speed bearings and yyj bearings? would a konkave or center trac fit a yyj yoyo? what are yoyo expert replacement bearings? ---

Also, with ceramic bearings, there’s people saying to clean, or not to clean… and ceramic is supposed to, spin longer as a result of less friction, and as an extension of that, also last longer than the average bearing. Not even sure if all those claims are true, and the extra spin time probably isn’t that much better. P.S. I personally wouldn’t get any of those bearings. I prefer to use the 10 ball… which isn’t mentioned here at all. 10 balls are a lot smoother to me, quieter, and also have a longer spin time. HOWEVER, normal bearings should serve you fine, and you probably shouldn’t need to buy new ones. I probably wouldn’t, but all my YYJ bearings died on me… they’ve rusted, gone clunky, and barely spin. All other bearings I have do not do this however. ---

Oh, from what I know, Ceramic bearings are built to last long. They’re like long term investments. Buy one expensive one, and it lasts like, very long. ---

I have a yoyo from 1998 and the same bearing works fine right now. It is just a cheap steel bearing.
