bearing not spinning?

I have a kk that I put into my DV888 but when i throw it, the yoyo spins for about a minute and when i looked in the gap, the bearing isnt spinning (it is spinning, just that the yoyo spins around it)
what could be the cause of this?

That’s the way it’s supposed to work.

You see the bearing has two rings, the bigger outer ring and the smaller inner ring. The inner ring is what the yoyo or bearing seat is touching, so that is what is spinning. The outer ring will stay stationary while the inner ring will spin as fast as the yoyo.

In short terms jhb8426 is right

no, you’ve got it right. that is supposed to happen.
