5*8*2mm ZrO2 full ceramic Bearing MR85
Because of its high compressive strength, contact fatigue resistance that is superior to chrome steels, electrical resistivity and low coefficient of friction versus bearing steels, silicon nitride ceramic bearings can be widely used in aviation, aerospace, marine, petroleum, chemical, automotive, electronics, metallurgy, electric power, textile, pumps, medical equipment, scientific research, national defense, military and other domains.
They can be used as high-speed bearings, high temperature bearings, corrosion-resistant bearings, shielded bearings, electrical insulation bearings and so on.

Granite Roll is used in old type machine, it is not very popular now, but there is still some old machines need granite roll as spare part in case of original granite roll damage. There is two kinds of granite roll, one is Natural Granite Roll and the other is artificial granite roll. These two types plays the same role. Usually, we suggest customers to install artificial granite roll, as this kind of granite roll can be repaired. But for natural granite roll, once there is any breaks on surface, then the whole roll can not be used anymore.
