High Efficiency Silicon Nitride Si3n4 Ceramic Bearing

Product Description:
Silicon Nitride (Si3N4) is a widely used ceramic material in high temperature application, it has high strength in both room temperature and high temperature condition, the strength of silicon nitride can be kept up to 1200ºC; the low coefficient of thermal expansion make it a ceramic material possessing excellent thermal shock resistance; at the same time, it also has good thermal conductivity.
Features of Silicon Nitride Bearing:

a. high temperature strength
b. superior thermal shock resistance
c. excellent wear resistance
d. good fracture toughness
e. mechanical fatigue and creep resistance
f. Excellent non-wetting property with good oxidationresistance
