Regarding synthetic sapphire bearings and ruby bearings, their hardness and ability can accept a high polish. They are recognized universally as the ideal jewel bearing material for instruments, meters, control devices and other precision mechanisms where low friction bearings, long life, and dimensional accuracy are needed. Ranking next to diamond in hardness, synthetic sapphire is identical in chemical composition to natural sapphire but is a far superior jewel bearing material because impurities and flaws are eliminated. Jewel bearings are used in a range of industrial applications.
