3.969mm Zirconia Ceramic Ball Hip ZrO2 high precision
Ø3.969mm Hip-ZrO2 Ceramic Ball With G5-G10 Grade For Ceramic Bearings
Description of Ø3.969mm Hip-ZrO2 Ceramic Ball:
Are made by highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material, 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, and our design annual output of Ø3.969mm Hip-ZrO2 Ceramic Ball can reach millions of pieces, which are suitable material for ceramic bearings with high precision.
