We are one of the few bearing specialists that have the ability to custom build ceramic bearings in our own "In-House" bearing lab in CHINA. Nowadays, everyone serious about performance is using ceramic ball bearings.

What is a Ceramic Hybrid Ball Bearing?

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.

Ceramic Balls run at lower vibration levels with less heat build up.

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.
