Information

1. Transmission device in high temperature equipment
 Si3N4The excellent high temperature resistance of ceramics makes its strength and hardness almost unchanged at 800°C, while the hardness of bearing steel decreases significantly when it exceeds 120°C.

2. High-speed operation field, high-speed electric spindle bearings, machine tool spindle bearings, dental drill bearings, instrumentation bearings
Si3N4The density of ceramic is3.20g/cm3,Much lower density than bearing steel 7.85g/cm3,Therefore, the ceramic rolling elements can effectively resist the centrifugal force generated by high-speed rotation and reduce the load of the rolling elements. At the same time, the rotation and sliding between the rolling element and the raceway can be reduced, and it has a beneficial effect on preventing surface damage. Ceramic ball bearings do not need to add lubricating grease frequently, and the characteristics of sensitive rotation, fast starting, good inertia and long life are fully reflected.

3. Aviation and aerospace fields
 Si3N4The coefficient of linear expansion of ceramic is3.2*10-6/K,Almost of bearing steel1/4,and so Si3N4Ceramic bearings are more stable when used in environments where temperature changes. For example, in the ultra-low temperature environment, ceramic materials exhibit excellent performance and are a candidate material for a new generation of hydrogen engine bearings.

4. Chemical machinery and equipment, food, marine and other fields
Ceramic bearings can solve the corrosion problem.

5. High vacuum field
Using the self-lubricating properties of Si3N4 ceramics can solve the vacuum pollution caused by the use of lubricating media in steel bearings.

6. Strong magnetic field environmentIn a strong magnetic field environment, the metal micropowder worn down by the steel bearing itself is firmly adsorbed between the rolling elements and the raceway surface, which will cause early spalling damage and increased noise of the bearing. The solution is to use ceramic bearings.

7. Civil products such as bicycles, roller skates, model airplanes and electric toys
Ceramic bearings are widely used in bicycles, roller skates, model airplanes and electric toys with their advantages of being lighter, more wear-resistant and faster, and are especially popular among top players in these fields.
