상품 특징

• Size：Zirconium Oxide Solid Ball diameter 3.175 mm/0.125 in, precision grade G10, Error ± 0.25 μm, density 6.00g/cm³; package includes 6 pcs zirconium oxide solid balls, with regular spherical shape and smooth surface without defects
• Material：Ceramic ball made of high-purity zirconia ceramic (ZrO2), HRC hardness up to 71, far exceeding ordinary bearing steel, but its density and weight is lower than steel, make small centrifugal force during rotation, enabling high-speed operation of equipment
• Stable Performance：The zirconium oxide balls, have stable chemical properties, hardly reacting with any substances, won't be corroded in daily environments; excellent heat resistance—strength and size remain at 600℃ high-temp; non-magnetic and with good electrical insulation, well stable performance
• Self-Lubricating：The zirconia ceramic ball is smooth and low friction coefficient, featuring excellent self-lubricating performance, no additional lubricant needed, maintain the equipment cleanliness and save the cost also
• Applications：Zirconia ceramic balls can serve in full ceramic bearings, composite bearings, pumps and valves, check valves, precision instruments, LCD manufacturing equipment, semiconductor, ; also applicable in harsh or vacuum environments
