The gas seal ring is a special bearing seal ring, which uses the pressure difference of the gas to achieve the sealing effect. The gas seal ring is suitable for high-speed rotating bearings, which can effectively prevent the leakage of lubricating oil and grease and improve the working efficiency of bearings. At the same time, the gas sealing ring can also prevent external impurities from entering the bearing interior and protect the normal operation of the bearing.

The liquid sealing ring is a bearing sealing ring that uses the viscosity and surface tension of the liquid to achieve the sealing effect. The liquid seal ring is suitable for high-speed rotating bearings, which can effectively prevent the leakage of lubricating oil and grease and maintain the lubrication state of the bearing. Compared with the gas seal ring, the liquid seal ring has a better sealing effect, but the manufacture and installation are more complicated.
