Hybrid ceramic bearingsSi3N4 ceramic bearingsZrO2 ceramic bearings

 

Advantages of Ceramic Bearings

essentially increased life time

high stiffness because of high Youngs modulus,lower vibration

wear resistance and cost effective lubrication

electrical insulation and non-magnetism

high temperature resistance up to 1000oC

high corrosion resistance to most acids and alkalies

 

Categories of Ceramic Bearings

 

Silicon nitride ceramic bearings:the rings and balls are all silicon nitride ceramics with cages made by PTFE, PEEK etc.

Zirconium oxide ceramic bearings:the rings and balls are all zirconium oxide ceramics with cages made by PTFE,nylon strengthened by glass fibles.

Hybrid ceramic bearings:the balls are made by silicon nitride ceramics, rings by bearing steel or stainless steel. The bearings have the advantages of long service life,high speed and super precision.
