Bearings
Properties of Full Cearmic 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.
