Ceramic bearings are comprised of ceramic rolling elements (balls) enclosed in a ferrous

(typically steel) inner and outer race. Since these bearings are constructed from many

materials, they often operate in hybrid capacities. We also build ceramic bearings (i.e.,

bearings with ceramic races), but they are not as common because they are less durable.

Reduced rolling resistance mainly results from the ceramic balls’ increased smoothness,

dimensional stability, and increased uniformity over steel ball bearings. These properties

ensure that applied loads are uniformly distributed over all rolling elements. Additionally,

ceramic materials have a significantly lower coefficient of friction (~20–30 times less) than

steel ball bearings with standard seals and lubrication. This reduced friction results in

reduced rolling resistance and faster rotational speeds.
