I have not been actively maintaining my yoyo parts recently, and now, I found a few unlabelled bearings in my collection. I am not sure what bearings they are, so I would like to inquire, how do I recognize a YYJ Speed bearing? Does it have any distinguishing features?
does it matter? a bearing’s a bearing. I honestly don’t see a noticeable difference in play from a ceramic kk to a yye bearing, or a crucial groove to a terrapin x.
While it might not matter sometimes, but it’s always a good to be able to identify and differentiate your bearings. It would help in describing your setup to others, or when selling them with your yoyos.
