Silicon Nitride Ceramic Ball:

Silicon Nitride Ceramic Ball is made of the hot isostatic pressing and sintering furnace and has the properties  including high strength,high wear resistance,high temperature,corrosion,acid and alkali resistant,long-term using in the sea,good electrical insulating ect.

 

The precision Si3N4 Ceramic Ball of Innnovacera produce is widely used in a  a variety of high-precision, high-speed / ultra-high-speed bearings, vacuumbearing, high / low temperature bearing, non-magnetic bearing.It is also as the measurement ball  used in chemical valve,high temperature valve,meter valve ect.The field of the application involve chemical, metallurgical, medical, food, oil, electronics,aerospace,ect.

 

* Fine crystalline Never rust,
* Can roll without oil or grease,
* Excellent corrosion resistance withstands attack from harsh chemicals and demanding environmental conditions,
* Lightweight: Silicon Nitride weighs 60% less than steel which reduces centrifugal force, skidding,
* Wear under high speed and acceleration.
