I opened up my YoYo Jam SPEED bearing and I noticed that it has ten balls in it. I thought the One Drop bearing was special because it has ten balls ???
I’ve also seen many SPEED bearings with 10 Balls. I want to know why too…
Within reason, the number of balls in a bearing has little affect on how it plays. Bearing quality can be felt to some extent, but if all you want is an unresponsive yo-yo then the biggest factor affecting you is the amount off oil in the bearing.
Do you know why they have 10 balls in speed bearings? ???
Because they can.
