Product Overview

Description

Product Description
Zirae ZSN-1 Silicon Nitride SI3N4 Ceramic balls

Silicon Nitride has the most versatile combination of mechanical, thermal, and electrical properties of any technical ceramic material. It is a high performance technical ceramic that is extremely hard and has exceptional thermal shock and impact resistance. It surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance and high strength. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications. Zirae ZSN-1 Silicon Nitride is an excellent choice when high-temperature and high-load abilities are needed.

Differences

1. What is the difference between Si3N4 and ZrO2 material?

Main Differences:
--Density: Si3N4 (3.2 g/cm3 ) Ceramic Bearing is lighter than ZrO2 ( 6g /cm3 )
--Using Temperature: Si3N4 1000°C, ZrO2 800°C
--Hardness: Si3N4 1700, ZrO2 1300.

2. What is the advantage using the ceramic bearing compare to standard steel bearings?
--Ceramic Ball Bearing can be in a high temperature(Si3N4 1000°C, ZrO2 800°C) working condition and dimention stability is very good. But stansard steel bearing can not work in a high temperature more than 200°C, and dimention stability is not good.
--Hardness: Si3N4 1700, ZrO2 1300, GCr15 800
--Corrossion Resistant: Ceramic Bearing is very very good and can work in a acid alkali environment. But standard steel bearings are always east to get rusty.
--Density: ceramic bearing is much lighter than steel bearings.
--Ceramic bearing : oilless self-lubrication

Application

suitable for automotive,Balls & Bearings,Electrical & Electronics
