These full ZrO2 ceramic angular contact ball bearings are designed for exactly those conditions — delivering reliable rotary performance where conventional steel bearings fall short.\u003c\/p\u003e\n\u003cp\u003eEach bearing is constructed entirely from zirconia (ZrO2) ceramic — inner ring, outer ring, and rolling elements — with no metallic components. Available in 17 size variants spanning the 7000 and 7200 series, with bore diameters from 10 mm (0.39 in) to 40 mm (1.57 in) and outer diameters from 26 mm (1.02 in) to 80 mm (3.15 in). Angular contact geometry supports combined radial and axial loads simultaneously.\u003c\/p\u003e\n\u003cp\u003eTypical applications include CNC spindle assemblies requiring non-magnetic bearings, chemical processing pumps exposed to aggressive media, food and beverage equipment where lubrication contamination is a concern, and medical or laboratory instruments where electrical isolation is critical.
