Bearings
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 ZrO2 material
Full ceramic bearing have excellence performance as special electrical and magnetism resistance wear and corrosion resistance lubrication and maintenance free when working especially high and low- temperature application .etc. could be used in awful environment and specially condition. The rings and balls made by full ceramic material: ZrO2 as a standard construction the cage made by PEFT.
