Zirconia Oxide Balls

Zirconia Oxide Ball (ZrO2) bearings are kept in our stock series. Zirconia has the highest strength and toughness at room temperature of all the advanced ceramic materials. ZrO2 ball offers superior load bearing capability, easily polished to finer surface finishes. Ortech Zirconia ball manufacturing capability ranges in size from 0.5mm to 38.1mm Zirconia Oxide Balls Grade Table ABMA Grade Round DIA Toler Per Ball Basic DIA Toler Surface Roughness in Micro-inches 3 .000003″ (.08) ±.000030″ (±.75) 0.5 (0.012) 5 .000005″ (.13) .000050/-.000040 ( 1.25/-1) 0.8 (0.02) 10 .000010″ (.25) .000050/-.000040 ( 1.25/-1) 1.0 (0.025) 16 .000016″ (0.4) .000050/-.000040 ( 1.25/-1) 1.0 (0.025) (microns)       Properties of Zirconia Oxide (ZrO2)
