Ceramic bearings are generally designed with a ferrous inner and outer ring or race with ceramic balls within the place of steel. Ceramic bearings offer several positive advantages over all of steel bearings, for example higher speed and acceleration capability, increased stiffness, lower friction and much more. Ceramic balls are usually nonconductive. Ceramic bearings can be found in all standard industry configurations for example, Ceramic angular bearings, Ceramic thrust bearing, Ceramic pillow block bearing, Ceramic needle bearings, Ceramic ball bearings and ceramic roller bearings.
Because ceramic is often a glass like surface it comes with an tremendously low coefficient of friction which is suitable for applications aiming to reduce friction. Ceramic balls require much less lubrication and also have a better hardness than steel balls that will lead to increased bearing life. Thermal properties are superior to steel balls leading to less heat generation at high speeds. Ceramic Bearings or Ceramic ball bearing may have a retainer traditionally made from PEEk and PTFE.
Ceramic Bearing can continue to operate under very high temperatures and they are able to operate as much as 1800 Deg. F. Ceramic ball bearing is quite a bit lighter than steel bearing and plenty of bearings are 1/3 the weight of a similar steel bearing. Ceramic bearings are remarkably corrosion resistant and can resist most popular acids, they won't corrode in contact with water or salt water. And lastly Ceramic Bearings are non-conductive.
Ceramic Bearings are particularly suited to applications where considerable shaft misalignment is to be expected. Ceramic Bearings also provide the minimum coefficient of friction of all rolling bearings so it's capable of running cooler at higher temperatures. Many high-speed electric motors needing voltage isolation can also utilize cermic bearing.
