Description: Bearing size: 9mm(ID) x 22mm(OD) x 7mm(W) Balls: Si3N4 Silicon Nitride ceramic balls Type: Deep groove ball bearing Cage: Nylon high speed balls retainer Closures: 2 x rubber sealedThis list for one ceramic bearing. 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.
