The Full Ceramic Angular Contact Bearing series is suitable for use in many specialty applications 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. These bearings come with Zirconia Dioxide (ZrO2) races and Silicon Nitride (Si3N4) balls. The balls are held in place with a PEEK or PTFE retainer and they are offered sealed or open. The sealed bearing are sealed with either PTFE or PEEK seals.
