 Ceramic  Bearings Si3N4 With Ceramic Material Have Below Features:

1.Can working at high temperature 800 degree ~1300 degree

with low coefficient of friction ceramic bearing have the ability to withstand much higher speed without exceeding too high temparature than steel bearings

2.Anti coorrosion

ceramic resists acids alkali blood salt and water ,so it will not corrod or rust

3 .No grease required

Ceramic balls require less lubrication and have a greater harness than steel balls which will contribute to increase bearing life .

4. Highest spin time

Because the ceramic has low coeffient of friction ,it is good material for any application seeking to have a high RPM'S
