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
Ring Jewels serve as radial or sleeve bearings used with straight cylindrical shafts. They offer flexibility in design through very many possible combinations with endstones.
Ring Jewels can be mounted into bushings or screws. This style can ease your mounting of the bearing into your final instrument.
Endstones find wide use as a thrust bearing in combination with a ring jewel which serves as the annular bearing.
Vee Jewels are well suited to sensitive instruments where the moving element is light.
Vee Jewel Assemblies are typically mounted in screws. This style can ease your mounting of the bearing into your final instrument.
Cup Jewels are generally used with a semi-spherical pivot or in a design that fits a ball bearing between two cup jewels.
