Jewel Bearing

Industrial jewels including sapphire have superior abrasion resistance, a low friction coefficient, and little heat variation, making them an optimal component for the instruments that require stable measurement over a long period of time. Many bearings made from jewels or ceramics are used for the bearing mechanisms of various measurement instruments; sapphire, ruby, ceramic, zirconia, etc. are selected according to the applicationin.

Typical Jewel Bearing Applications:

Flow Meters
Gauges,Meters, Indicators
Aircraft Instruments
Gyros
Watches, Clocks
