R22 Full Ceramic Bearings (1-3/8″ X 2-1/2″ X 7/16″)

R22 Full Ceramic Bearings are made entirely of ceramic material . Ceramic is the perfect material for any application where high temperatures and corrosive substances, High RPM’s, reduce overall weight or for extremely harsh environments. Full Ceramic bearing materials commonly used are Silicon Nitride (Si3N4) and Zirconia Oxide (ZrO2). We can custom made full ceramic bearing in Alumina Oxide (Al2O3) or Silicon Carbide (SiC). Here at Ortech, we hand make every single full ceramic bearing so that each customer can chose the ceramic material, cage/retainer, open or sealed along with the type of seal. We can also custom make the different ABEC Rating  and the clearance of each bearing. If you do not see a specific type of bearing on our website, please send us a quote request for custom bearings.
