Power Transmission Products 6904 6904CE Full Ceramic Bearing 20379 mm ZrO2 Material All Zirconia Ball Bearings

Bearings1 Properties of full ceramic 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.2 Structure of full ceramic BearingsFull ceramic (All-ceramic) bearing of ZrO2 materialFull 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.
