1 Properties of full ceramic materials
Ceramic Bearings including components made from ceramic have the special properties that steel bearings do not have such as being non-magnetic or insulating. They can be used in new applications where conventional bearings have not been practical.
Ceramic Bearings are highly heat resistant enabling a rolling bearing to be practical in a high temperature environment. The low density of ceramic decreases the centrifugal force induced by rolling elements (balls or rollers) contributing to an increased speed of the apparatus.
2 Structure of full ceramic Bearings
Full ceramic (All-ceramic) bearing of Si3N4 material
Full ceramic bearing made with Si3N4 have some better performance than ZrO2 the rings and balls made by full ceramic material:Si3N4 as a standard construction the cage made by PTFE Compares than the material of ZrO2 The SiN4 ceramics bearings could endure heavier load and could be used in higher temperature environment.
