R4 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.
R4 full ceramic High-corrosion resistant bearing are quite useful in applications where normal bearings are not enough. Ortech series Ball Bearings can be used in a variety of applications as they are self-lubricating. Hence they are perfect for corrosive environments and non-magnetic applications right from normal atmosphere to vacuum.
