R188 - FULL CERAMIC 9 BALLS WHITE BEARING
This bearing features 9 ceramic white balls, white ceramic races and a beige cappuccino ceramic cage. Also, remember that this type of bearing gets better and better with time and use, since the bearing can breakdown and polish itself with use (true for any full ceramic bearing of any size). In other words, you get longer spin time with long term use. Notice that full ceramic bearings are usually not silent or smooth. They have a strong feedback.
