Si3n4 Zirconia Ceramic Balls Grinding Media Rollers G5 G40 Grade
Zirconia Ceramic Beaing Balls/Rollers Of Customized Size With High Precision
Description of Zirconia Ceramic Balls/Rollers:
Our zirconia ceramic balls/rollers 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. At present, our company has two production lines specializing in the production of high-precision ceramic balls, and can produce customized zirconia balls or rollers, which are used as ceramic bearing balls., whose accuracy level shall reach to G3, G5 and G10 or quality is equivalent to ASTM F2094 F2094M-08 grade I and II materials. Our producible size range of ceramic balls and ceramic ball valves is from 1.588mm to 60mm.
