Center Trac bearing is a designation for a concave bearing from Yoyofactory.
This is a non-responsive bearing. This means that with it, the yoyo returns to a trick called BIND (not a twitch) and is suitable for more advanced tricks.
The great advantage of concave bearings is the profile, which is curved, so it keeps the strings always in the middle and the yoyo brakes less.
The package contains only 1 bearing.
- size C or “large bearing” – fits the vast majority of yo-yos. If you don’t know how to choose a size, size C is probably what you’re looking for
- size A or “small bearing” – fits only in a few yo-yos, such as Loop360 or Freehand Zero.
