Application of Ceramic Balls :
Ceramic ball can be used in all bearings with special requirement, metering ball , valve ball, track ball, and precision grinding ball; it can be used in fields requiring chemical resistance, high temperature, electronic insulation, magnetic insulation, non-lubrication. It is an idea substitute for steel ball in chemical corrosion application.
Material: Zirconia, Alumina, Si3N4
Size Range: 1mm - 30mm.
Grade: G3 - G20

6004 1300 Centigrade High Temperature Silicon Carbide Ceramic Ball BearingIf you are interested in our products and want to know more details,please leave a message here,we will reply you as soon as we can.
6205ZZ bearing size 25*52*30mm ,with ceramic balls and high temp alloy steel material,and we packed with Japan grease DOWCORNING grease can used in high temp area such as Waffle Roasting Machinery .
6203 high temperature bearings mainly refer to the common bearing structure, using high temperature resistant materials, such as high temperature grease; and the bearing clearance is much larger than ordinary bearings , so it is usually not suitable for high speed operation, it is a high temperature low speed bearing. High temperature bearings are widely used in high temperature operation machinery such as metallurgy, kiln, glass, blast furnace, painting equipment.
6316 Ball Bearing size is 80*170*39mm,we use high quality material alloy and Ceramic and packed with JAPAN brand grease DOW CORNING can work at temperature moer than 500 ° C。
