Zr02 Zirconium Oxide Balls 4.763mm G5-G10 Grade
ZrO2 Ceramic Ball of Ø4.763mm With G5-G10 Grade For Ceramic Bearings
Description of ZrO2 Ceramic Ball of Ø4.763mm:
Our zirconia ceramic balls are made by highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material and are processed by AP (Atmospheric Pressure) sintering and HIP (Hot Isostatic Pressure) sintering technology, so their porosity, wear resistance, impact resistance and resistance to fatigue contact life are greatly improved. At present, our company has two production lines specializing in the production of high-precision ceramic balls Because of the good properties of zirconia, ceramic balls in material of zirconia fitted in bearings can improve the bearings operating performance.
