Can I use this bearing?

The roller next to your finger appears to have a problem. Maybe just grease but I can't tell by the photo. If that is just grease, I see nothing wrong. You would do well to clean them better then work completely clean and inspect them again.

I saw this too, right next to his thumb. Hopefully grease. I used compressed air to blow out all of the old grease that will come out, then wash them in a container with mineral spirits. I have a real nice Graymills parts washer but it need a complete refill and that has become too expensive, so I just buy mineral spirits at Wal-Mart in the paint section (cheaper than Home Depot or Lowes) and use that. Once I have managed to swish all the grease out of the bearing (technically a "cone"), I blow it dry (don't spin it) and if it and the race (technically a "cup") are good, then I repack it.
