Bearing Depot & Supply stocks a full line of ceramic ball bearings for use with RC, Bicycle, and all motorsport applications.  Silicon Nitride ceramic ball bearings are superior to common steel ball bearings in many ways. Ceramics are perfect materials for any application seeking to achieve higher RPM's, reduce overall weight or for extremely harsh environments where there are high temperatures & corrosive substances. Ceramic bearings weigh 40% less, operate at higher speeds and run cooler. Will also last 3-5 times longer. Applications such as motor sport, cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics & optics. Ceramic balls have a glass-like surface - it has an extremely low coefficient of friction, high rigidity, and corrosion resistance. They are ideal for applications seeking to reduce friction and noise. Ceramic ball bearings require less lubrication and have a greater hardness than steel balls and will contribute to increased bearing life. Thermal ceramic properties are better than steel balls resulting in less heat generation at higher speeds. The Bearing Depot stocks a large line of great quality manufacturers that are trusted by our loyal customers including NTN, Nachi, FBJ, Koyo. To search our ceramic series start with "CB"
