Self Aligning Full Ceramic Bearings

Full Ceramic Self Aligning Bearings are made entirely of ceramic material and are superior to common steel 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. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), Alumina Oxide (Al2O3) or Silicon Carbide (SiC.)

A Full Ceramic Self Aligning Bearing has two rows of balls and one, concave spherical raceway in the outer ring. As a result the bearing is self-aligning and insensitive to misalignments of the shaft in relation to the housing. Full Ceramic Self Aligning Bearings are particularly suitable for applications where considerable shaft misalignment is to be expected. Full Ceramic Self Aligning Bearings also have the lowest coefficient of friction of all rolling bearings so it is capable of running cooler at higher temperatures. The Boca Bearing Company specializes at miniature and ceramic self aligning bearings.
