A Ceramic Hybrid Bearing combines ceramic balls with quality steel rings. The ceramic balls were first invented by NASA, entering widespread usage in the 1990s for use in electrical motors. The use of ceramic balls in place of steel can radically improve performance due to 60% reduction in weight, and an almost perfectly smooth surface that reduces vibration levels by 2 - 7 times. They can also operate at significantly loser operating temperatures, and lower operating temperatures extends the life of the bearing.
