What is the use value of ceramic bearings?

Bearings are an important basic component of mechanical machines, etc. However, bearings also have many materials, and the mechanical equipment suitable for different materials will have certain differences. Maybe you don't know much about ceramic bearings, so let's introduce ceramic bearings to you.

What is the use value of ceramic bearings?

1. ceramic bearings have the advantage of zero corrosion. It can be used without hindrance even in unsatisfactory corrosive working environments.

2. No matter whether the temperature suddenly rises or drops suddenly, the ceramic bearing can also not be affected by any.

3. The biggest feature of ceramic bearings is that they will not be deformed by force, because the elastic modulus of the bearing is higher than that of steel.

4. The density of the ceramic rolling ball is much lower than that of steel, so the weight is naturally much lighter, so the centrifugal friction of the outer ring can be reduced, and the service life of the natural ceramic bearing will be longer.

What are the characteristics of ceramic bearings?

(1) High-speed bearing: It has the advantages of cold resistance, small force elasticity, high pressure resistance, poor thermal conductivity, light weight, and small friction coefficient. It can be used in high-speed spindles from 12000 rpm to 75000 rpm and other in high-precision equipment;

(2) High temperature bearing: The material itself has a high temperature resistance of 1200 °C, and is self-lubricating, and the operating temperature is between 100 °C and 800 °C without expansion due to temperature difference. It can be used in furnaces, plastics, steel and other high temperature equipment;

(3) Corrosion-resistant bearings: The material itself has the characteristics of corrosion resistance, and can be used in strong acid, strong alkali, inorganic, organic salt, seawater and other fields, such as: electroplating equipment, electronic equipment, chemical machinery, shipbuilding, medical equipment, etc.

What are the raw materials of ceramic bearings?

Zirconia

All-ceramic bearings have the characteristics of anti-magnetic and electrical insulation, wear resistance and corrosion resistance, oil-free self-lubrication, high temperature resistance and high cold resistance, and can be used in extremely harsh environments and special working conditions. The ferrule and rolling element are made of zirconia (ZrO2) ceramic material, and the cage is made of polytetrafluoroethylene (PTFE) as a standard configuration. Generally, glass fiber reinforced nylon 66 (RPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.

Silicon Nitride

Silicon nitride full ceramic bearing rings and rolling elements are made of silicon nitride (Si3N4) ceramic materials. Generally, RPA66-25, PEEK, PI, and phenolic cloth bakelite tubes can also be used. Compared with ZrO2 materials, all-ceramic bearings made of SiN4 can be used for higher speed and load capacity, as well as for higher ambient temperature. At the same time, it can provide precision ceramic bearings for high-speed, high-precision and high-rigidity spindles, and the highest manufacturing accuracy is P4 to UP.
