Full ceramic bearing of full complement balls of ZrO2 material has an add-ball gap on its side. Because using no cage design, the bearing able to install more ceramic balls than the standard construction, so the heavier radial load ability increased more. In addition, to avoid the limited of the cage material, this bearing same as the full ceramic bearing of ceramic cage has corrosion resistance and high temperature application. This series of bearing is not for high speed choice, it should be to install on the unforced side. As there have in the inner and out rings the bearing couldn't be used in axial load application.The highest temperature of recommendation is 500¡æ.
