Below is a list of Ceramic Ball Bearings manufacturers from Eden Prairie, Minnesota. Ceramic ball bearings are rolling-element bearings made from ceramic materials that provide smooth, low-friction radial or axial motion in a spinning system. Ball bearings are composed of three main parts: an inner ring, an outer ring and the balls. The rings are also called races and are what the balls travel along. Many ceramic ball bearings also have separators that keep the balls from coming into contact with each other.
