R188 Full Ceramic Bearing ZrO2/Si3N4 1/4" x 1/2" x 3/16" Ball Bearings

I have tried all of the ceramic bearings for hand spinners. This one is my favorite. When I put this bearing into a spinner, I get the longest spin times with that spinner ever.. Now that I found the best bearing, this is the one I will buy 4 or 5 of for other spinners.. Ceramic bearings are very noisy though. A chrome steel bearing is whisper quiet, and will still spin for a long time. If the ceramic spins for 10 minutes, the chrome would spin for 7 minutes. So there is a trade off for the longest spin time also gives you the noisiest spin..

My spin times with an Atesson spinner went from over 6 minutes average and quiet with a Coogam Hyrbrid bearing to just over 3 min average and noisy with this. I'm going to allow a break in period and see if it gets better. I will update if it does.
