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

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.
