2PCS  6806-2RS Stainless Steel Full sealed Hybrid Ceramic Bearing si3n4 Ball 

 
 

Description

Silicon Nitride ceramic  ball bearings are superior to common steel ball bearings in many ways.  Ceramic is the perfect material for any application seeking to achieve  higher RPM’s, reduce overall weight or for extremely harsh environments  where high temperatures and corrosive substances are present. Applications  such as cryopumps, medical devices, semiconductors, machine tools, turbine  flow meters, food processing equipment, robotics and optics.
Because ceramic ball is a glass like surface it has an extremely low  coefficient of friction, high rigidity, corrosion resistance and is ideal  for applications seeking to reduce friction. Ceramic balls require less  lubricant and have a greater hardness than steel balls which will contribute  to increased bearing life. Thermal properties are better than steel balls  resulting in less heat generation at high speeds.
