In this video i'm showing the main difference between standard steel ball bearings and full ceramic ball bearings which is the amount of friction that each has. You can immediately see the difference as soon as both are spun. I bought these in order to install them in my CNC steam turbine and see if it can actually produce more power for which i doubt that it will make a huge diffence, but we shall see;)
