Products Description

Balls & balls measuring head 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.

Cup jewels are chiefly applied to electronic meter, hot water meter, liquid measuring instrument and movement system of single-phase and three-phase 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.
