What Material Is Good For Bearing Washer

Bearing sealing washer is the main application of sealing device in industrial equipment, also known as pressure seal. It is a bearing sealing washer based on the physical principle and pressure difference principle, that is, using the sealing structure to make the pressure in the sealing chamber different from the ambient pressure. The principle of sealing gasket involves the knowledge of sealing materials, surface science, fluid mechanics, lubrication concept, thermodynamics and tribology. The structural types of seals are mainly divided into static pressure seals and dynamic pressure seals. Static pressure sealing means that the sealed surface has no relative movement. The function of sealing is to separate the two spaces and ensure that the substances in the two spaces do not exchange. As for the dynamic sealing gasket and the static sealing gasket, its surface has relative movement. It relies on the dynamic pressure effect of the fluid to separate the sealing space and the environmental space. The dynamic sealing gasket can be divided into straight seal and labyrinth seal.
