Product Description

Silicon Nitride Precision ceramic balls have excellent properties such as high strength, good wear resistance, corrosion resistance, high temperature resistance, electrical insulation, and non magnetic properties that metals do not possess. They are ideal products for use in the bearing industry, chemical industry, and valve industry.

 

Features
* High hardness, goodresistance, and long service life
* High temperature resistance, maintaining high strength and hardness even at a high temperature of 1200
* Low density and high densification
* Self-lubricating never rusting
* Low coefficient of themal expansion, high thermal shock resistance
* Anticorrosion of acid and alk

* Nonmagnetic and electrical insulation
* At high temperatures, it does not adhere to the metal and hardly reacts

 

Our Silicon Nitride Ceramic Ball size is from 0.5mm to 38mm( from 8/5" up to 2-1/4" ) and there are many Size and Grade for choose, such as G5 , G10, G100 and so on. Many Sizes are stock have, so the lead time is very short. Silicon Nitride Ceramic Bearing Balls are widely use in oil industry, copper tube manufacture , hybrid bearing and full ceramics applications.
