Loose Ball Bearings

          Found in virtually all moving mechanisms, bearings are hardly given a thought until something starts to grind -- or falls apart. Unlike caged or roller bearings, which are enclosed in a casing, loose ball bearings float freely between metal cups, or "races." Most are commonly found in older applications, loose bearings are used to maintain proper tolerances between two or more moving pieces of a rotating part, such as steering mechanisms or wheels. Since they are not secured inside a housing, loose bearings must be inserted one at a time.

           Loose Ceramic Ball Bearing, We have 2 types of ceramic bearing, hybrid ceramic bearing and full ceramic bearing, 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.
