Magnetic BearingsBearingProperties of Full Cearmic MaterialsCeramic 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.Widely used in household appliances, garden machinery, outdoor vehicles, industrial production, etc. Suitable for skateboards, longboards, inline skates, scooters, robots, ship rudder axles, etc.Features: small friction, fast speed, smooth, low noise.
