Silicon Nitride Ceramic Ball:

 

Silicon Nitride Ceramic Bearing Ball is formed from a new material suitable for applications where high loads, high speeds and extreme temeratures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Silicon Nitirde is non-porous, non-magentic, non corrosive, lighter than steel and, in ball form, is harder than steel. Because ceramic balls are non-porous they are virtually frictionless and are capable of spinning faster than steel balls.

Silicon Nitride Balls Advantage:
* 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.

 

 

Our Silicon Nitrided Ceramic Balls 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.
