Jewel Bearings

Synthetic sapphire and ruby, because of their hardness and ability to accept a high polish, are recognized universally as the ideal jewel bearing material for instruments, meters, control devices and other precision mechanisms where low friction, long life and dimensional accuracy are important. 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
