◎ Transferring Device in High-temperature Equipment
Excellent resistance to high temperature of Si3N4 ceramics makes its intensity and hardness almost unchangeable under 800 ℃ , while the hardness of bearing steel reduces distinctly when temperature exceeds 120 ℃ .

◎ Area of High-speed Running: high-speed electric main spindle bearing, machine tool main spindle bearing, dental drill bearing, computer hard disk drive bearing and instrument and meter bearings.
Density of Si3N4 ceramics is 3.20g /cm3, much less than the bearing steel density of 7.85g /cm3. So ceramics rolling element can effectively restrain the centrifugal force produced by high-speed running, reduce the load of rolling element, and decrease the rotational slide between rolling element and rollaway nest and do good to prevent surface from being damaged at the same time. Ceramic ball bearing can fully reflect itsadvantages of sharp running, good inertia and long life needless of adding lubricating greases always.

◎ Aviation and Spaceflight Areas
Linear expansion coefficient of Si3N4 ceramics is 3.2*10-6/K, which is one-fourth less, so Si3N4 ceramic bearing is more stable and dependable used in environment with changeable temperature.

◎Machine Tool Main Spindle and Other Processing Centers
Hardness of Si3N4 ceramics is one time more than that of bearing steel, gauge high of elastic modulus is about one-third, and under conditions with same load, its elastic deformation is small, so ceramic bearing has excellent processing precision.

◎ Chemical Mechanical Equipment, Food, Ocean and Other Departments
Ceramic bearing can solve the problem of corrosion.

◎ High Vacuum Area
Utilizing self lubrication ofSi3N4ceramics can solve the vacuum pollution caused by that steel bearing uses lubricating medium.

◎ Environment with Strong Magnetic Field
Under environment with strong magnetic field, owing to metal miropowders worn by steel bearing self are firmly adsorbed between rolling element and rollaway nest face, the bearing will flake off and break down ahead of time and noises will be increased. The solution is just using ceramic bearing.

◎ Roller Skates, Aeromodelling, Electric Toys and Other Civilian Industry Products
Because of price and others, applications of full ceramic bearings in the global will suffer from many restrictions. What apply more are ceramic hybrid bearings with balls as ceramics, the ceramic hybrid bearings with metals on inner and outer rings mainly apply to high-speed and high-precision areas. The company adopts near net dimension modeling technique to greatly reduce production cost of ceramic bearing ball, making ceramic bearings not only have aforementioned applications, but also apply to civilian industry products such as roller skates, aeromedelling, electric toys and so on.
