Product Description

Zirconia Polish Balls are developed for high-end customers. They are engineered for high temperature resistance, higher wear resistance, and better size distribution. ZrO2 Precision Balls are practical in high-speed vertical and horizontal mills. They are ideal for ultra-fine grinding of thermo sensitive material, electronic ceramics, paint, and nano-materials etc. They are corrosion resistant and longer lasting. 

Key Features:  

  • Excellent Size Range and Grade  
  • Lighter than steel ball 
  • Smaller friction coefficient
  • Can be utilized at higher temperatures
  • Roll without lubrication
  • No metal contamination
  • Non-magnetic and Electric isolation


  • Size Range: 0.4mm~80mm(1/64"~2") with different gauge.
  • Grade: G5~G60
  • Company Feature: ZrO2 density is higher than 6.05g/cm3
  • Certificate:
  • Sintech Si3n4 Ceramics has achieved ISO 9001:2015Certificate. Our ceramic bearing and ceramic ball products were recognized as Hi-Tech Project by Shanghai government respectively.

Compared with steel ball, ZrO2 ball has following advantages:

  • 23% lighter than steel ball, which means less centrifugal force and less friction on the groove during high speed and acceleration.
  • Smaller friction coefficient, more freely rolling
  • Can be used at higher temperature up to 750°C
  • Never rust, and can roll without lubrication
  • More corrosion resistant than steel
  • No metal contamination
  • Non-magnetic
  • Electric isolation


Zirconia balls are mainly used for ceramic bearing, valve ball, track ball, metering ball and precision grinding ball. Also, they are successfully used in diaphragm pump, oil well pump, metering pump, high pressure sprayer etc. 


  • White color as standard
  • Plenty of stock
  • Non-standard size could be supplied
  • Thermal expansion coefficient of ZrO2 is 10.5*10-6/°C, similar to that of steel, which, means ZrO2 has well fitting with metal. However, it also results in larger size change with temperature fluctuation. Also, ZrO2 fractures in rolling-failure, thus it is less stable than Si3N4 in key application.
