6082s 608z 608rs Full Ceramic Skate Bearings Roller High Precision
608rs Ceramic Bearings With High Precision For High-End Roller Skate
Description of 608rs Ceramic Bearing:
We can produce 608rs ceramic bearing in material of silicon nitride or zirconia. Our zirconia material is highly purified, sub-micron and after Y2O3 partially stabled zirconia powder material and silicon nitride material is highly purified, submicron silicon nitride powder with an alpha phase of more than 92%, besides we can make hot isostatic pressure sintering handle to improve the propertis and compactness of races and balls according to your need.
