CUP JEWEL BEARINGS
Cup jewel bearings have the advantages of abrasion resistance,low friction torque and high compressive strength, thus are widely applied to precision instrument industry, such as supporting the movable parts of electricity meter, water meter, high sped centrifuge,high speed energy storage flywheel,compass, meteorological instrument and aviation/navigation instrument, etc, having the feature of long life, high speed, high abrasion resistance and high sensitive.These cup jewels contain three types: conical bearings, single cup on double surfaces bearing and double cups on one face bearing.
