Ceramic sleeves is a ceramic connector for industry parts, They are used for wear resistance, high temperature, and corrosion resistant properties.

In the moving parts, because of long-term friction caused by the wear of parts, when the shaft and hole clearance wear to a certain extent must be replaced parts, so the designer in the design of the lower hardness, better wear resistance material for the shaft sleeve or bushing, so as to reduce the wear of the shaft and seat.s
