CUP JEWELS
Cup jewels are chiefly applied to electronic meter, hot water meter, liquid measuring instrument and
movement system of single-phase and triphase KHW meter.
These cup jewels contain four types: spherical bearing, conical bearings, double cups on one face
bearing, and single cup on double surfaces bearing.
Material
sapphire/ruby , natural agate,
crystallite glass and ceramic, etc
Order
Produce according to specific requirements and drawings, and also can design products for
customers.
Specification
HOLE JEWELS
Hole Jewel contains a series of components that are chiefly applied as supporting bearings to the rotational
systems of various accurate chronographs, auto-memorizing apparatus, precise instruments (micrometer, dial
indicator) and other apparatus.
Main types: Plane straight/olive holed bearing, single-cup plane straight/olive holed bearing, double-cups
plane straight/olive holed bearing, raised olive holed bearing, and single-cup raised olive holed bearing, etc.
Material
Synthetic sapphire/ruby single
crystal α-Al2O3, natural agate,
spinel, ceramic, etc.

JEWEL ROD&PISTON
Jewel rod&piston are made of sapphire/ruby ,they are widely applied to medicine, accurate machine, accurate
measure and inspection and laser technology. They also contribute a lot in the anticorrosion, wearable and hi
gh heat conduction environments.
Main types: sapphire/ruby rods jewels, single round end rods jewels, double round end rods jewels,
jewel rotor laterl pin,etc.
Material: Synthetic sapphire/ruby single cryst
al αAl2O3, zirconia ceramic, alumina
ceramic, SiC, Si3N4 and optical glass.

BALLS & BALLS MEASURING HEAD JEWELS
Balls & balls with drlled hole jewels are made of synthetic sapphire/ruby. They are largely used in heavily
corrosive environment and optical fiber communication because of its anticorrosion, wearable and fine
transmission characteristics. Balls measuring head jewels are used as insulated measure head on precise
instruments.
Material
sapphire/ruby , natural agate, silicon
carbide, ceramic, crystallite glass , spinel,
hard alloy etc.

SAPPHIRE SUBSTRATES & WINDOWS
Sapphire Substrates & windows are applied as circuit substrates, epitaxial substrates, substrates, oiented
substrates to GaN,GaAs. And other, Sapphire possesses nice light transmission in 0.20 ~ 5.50μm wave
band, and the infrared ray transmission is hardly influenced by temperature, so the optical components
made of sapphire are fully applied to military infrared equipment, observation window for high temperature
furnaces, windows for counters, etc.
Material
Synthetic /ruby , natural agate, crystallite
glass and ceramic, BK glass ,other
ultrahard materials ,etc.

JEWEL ASSEMBLIES & NOZZLE
Jewels assemblies contains a series of products: cup jewel, flat-end surface bearing, flat surface straight
holed bearing, flat surface olive holed ring, single cup straight holed ring, single cup olive holed ring, double
cups straight holed ring, double cups olive holed ring, etc. These components are embedded with stainless
steel, aluminum alloy, brass, and red copper, etc. assemblies Jewels are intensively used as movable and
supporting parts on accurate measuring instrument and military apparatus.
Nozzle Jewels are made of sapphire/ruby and embedded with brass, red copper, stainless steel and alloy.
They are chiefly applied to accurate measuring instrument, machinery, high-pressure water, liquid cutting,
medicine and various auto-memorizing apparatuses
