I ordered some Post for my PGM (stripped other pair) and I got my bearings and o-rings out. In my bearing (de shielded), on the edge I found this

It is clear small and round. It sticks to a pin and flings up when the need puts pressure on it. Could this be Dried lube? There where a few other small ones in the bearing.

It’s a YYF Hubstack A bearing.

Are you wondering if you should keep it or something?

It’s just debris - possibly some dry sili. Throw it out and throw your yoyo.

Keep it no, I was just curious. I did have it in a yoyo at one point because I stripped my post.
