Rolling resistance is the key trump card promoted by ceramic bearing fans.
What are ceramic bearings made of.
Full ceramic bearings have races and balls that are made entirely of ceramic material and are superior to common steel bearings in many ways.
Ceramic is the perfect material for any application seeking to achieve higher rpm s reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present.

Ceramic bearings are made from a compound called silicon nitride.
A ceramic is any of the various hard brittle heat resistant and corrosion resistant materials made by shaping and then firing a nonmetallic mineral such as clay at a high temperature.
While regular bearings are made from stainless steel ceramic bearings are made from ceramic silicon nitride si2n4.
Common examples are earthenware porcelain and brick.
Full ceramic radial deep groove bearings are made entirely of ceramic material and are superior to common steel bearings in many ways.
The silicon nitride compound is far lighter than your run of the mill steel bearing 60 lighter in fact and they are significantly harder than that of their metal counterparts.
