Ceramic bearings are made from a compound called Silicon Nitride. 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. These bearings operate at an 80% faster speed than that of standard bearings and they also self lubricate. They are made to not only withstand extreme physical impact, but also to perform exceptionally when under harsh circumstances, such as high temperatures, lack of lubrication, and in high corrosion environments.
