The hybrid ceramic bearing has steel inner and outer rings with ceramic balls, as for the full ceramic bearing; the inner, outer rings and the balls are made of ceramic. There are many kinds of ceramic materials, the most common ceramic materials are Si3N4 that stands for the silicon nitride ceramic material and is black colored, SiC stands for the silicon carbide material and also is black colored. and the ZrO2 that stands for the zirconium dioxide, also known as zirconia or zirconium oxide, they are white colored, a ZrO2 ball looks exactly like a pearl. the ceramic material is not stronger than steel, but ceramic bearing are lighter and have lower friction than steel, that makes ceramic bearing go faster with lower heat generated.
A Ceramic Hybrid Ball Bearing is a precision bearing in which one or all of its components are made of ceramic elements from silicon nitride. Silicon nitride is a highly processed silica and ceramic material, similar to the heat absorbing, highly resilient tiles on the Space Shuttle. These tiles are used to line the heat shield of the Space Shuttle, as they protect it from the 2500 plus degrees F. extremes of re-entry into the earth's atmosphere. The use of Ceramics for bearing components results in a far superior product over traditional all steel ball bearings.
There are basically three types of Ceramic Ball Bearings;
Ceramic "Hybrid" Ball Bearings; Where the rolling elements, or balls, are ceramic, but the inner and outer rings are still conventional steels.
"Partial" Ceramic Ball Bearings; Where the rolling elements, and the inner ring are ceramic, but the outer ring is still made of steel.
"Full" Ceramic Ball Bearings; Where the rolling elements, inner, and outer rings are made of silicon nitride.
