One side of fully loaded spherical all-ceramic bearing has a ball notch. Because of the non-cage structure design, more ceramic balls can be loaded than the standard structure of bearing, so as to improve its load capacity. In addition, it can avoid the limitation of cage material, and achieve the effect of corrosion and temperature resistance of ceramic cage all-ceramic bearing. This series of bearings are not suitable for higher speed, so it should be noted that the notched surface is installed at the end that does not bear axial load.
