Description
Zirconia balls (ZrO2 balls) for valves, ceramic bearing, measuring balls, trackballs, and precise grinding balls
The high tenacity zirconia balls (ZrO2 balls) made by Shandong EROAD uses sub-nanometer level raw material and processes by advanced technology. All the technical data has reached international advanced level and the cost performance is very competitive, which brings visible added value for users.
Production Capacity:
*Fine ceramics standard: ISO 26602-2017,ASTM F2094 F2094M-2018a
*Range:1mm-120mm.
*Grade:G10-G1000
Applications:
* Valves, ceramic bearing, measuring balls, trackballs, and precise grinding balls.
* Occasion of high temperature, anti-rust, insulation, anti-magnetism, no lubrication and etc., which is the ideal material to replace steel balls on some special occasions.
