| Strong points: | Application: | Size Range | Note: |
| 1. 23% lighter than steel ball, which means less centrifugal force and less friction on the groove during high speed and acceleration. | ZrO 2 ball is mainly used for valve ball, full ceramic bearing, metering ball, track ball, and precision grinding ball; it can be used in fields requiring chemical resistance, high temperature,electronic insulation,magnetic insulation, non-lubrication. ZrO 2 ball is an idea substitute for steel ball in chemical corrosion application. As valve ball, ZrO 2 ball is now successfully used in high pressure homogenizer, diaphragm pump, metering pump, oil well pump, high pressure sprayer etc | 0.4mm~50.8mm (1/64"~2") with different gauge | 1) white color as standard, yellow ZrO 2 ball could be supplied upon customer requirement. 2) plenty of stock. 3) non-standard size could be supplied. 4) thermal expansion coefficient of ZrO 2 is 10.5*10 -6 /°C, similar to that of steel, which means ZrO 2 has well fitting with metal. However, it also results in larger size change with temperature fluctuation. Also, ZrO 2 fractures in rolling-failure, thus it is less stable than Si 3 N 4 in key application. |
| 2. Smaller friction coefficient, more freely rolling. | |||
| 3. Can be used at higher temperature up to 750ºC. | |||
| 4. Never rust, and can roll without lubrication. | |||
| 5. More corrosion resistant than steel | |||
| 6. No metal contamination. | |||
| 7. Non-magnetic. | |||
| 8. Electric isolation. |
